.. default-role:: fs
=========================
Building |Tesseractocr|
=========================
The Visual Studio 2008 Solution for |Tesseractocr| builds:
+ `libtesseract`
+ `tesseract.exe`
+ 9 training applications (for v3.02)
Unlike earlier Solutions only a single `libtesseract` library is
generated --- the twelve projects matching the twelve source subfolders
have been abandoned. They were deemed too complicated since they were
never (rarely?) used by themselves, but only along with the entire
library.
In addition, `libtesseract` and `tesseract.exe` can be built using four
configurations: :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug`.
Two Visual Studio Property Sheets, `leptonica_versionnumbers.vsprops`
and `tesseract_versionnumbers.vsprops`, are employed to isolate the
Solution from changes in dependency version numbers (and isolate
dependent Solutions). See :ref:`APITest's <APITest>` :ref:`LIB_Release
<apitest-lib-release>` Linker :guilabel:`Additional Dependencies`
settings for an example of what this looks like in practice. See
|Leptonica|\ ’s explanation `About version numbers in library filenames
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers>`_
for the rationale behind using Property Sheets.
Building `libtesseract` and `tesseract.exe`
===========================================
1. Open `C:\\BuildFolder\\tesseract-3.0x\\vs2008\\tesseract.sln` in Visual
Studio 2008.
You'll see the following projects in the :guilabel:`Solution
Explorer` (for v3.02)::
ambiguous_words
classifier_tester
cntraining
combine_tessdata
dawg2wordlist
libtesseract302
mftraining
shapeclustering
tesseract
unicharset_extractor
wordlist2dawg
2. Select the build configuration you'd like to use from the
:guilabel:`Solution Configurations` dropdown. It lists the following
configurations::
DLL_Debug
DLL_Release
LIB_Debug
LIB_Release
The `DLL_` configurations build the DLL version of `libtesseract-3.0x`
(and link with the DLL version of Leptonica 1.68). The `LIB_`
configurations build the static library version of `libtesseract-3.0x`
(and link with the static version of Leptonica 1.68 and the required
image libraries).
3. Build `libtesseract` by right-clicking the
:guilabel:`libtesseract30x` project and choosing
:menuselection:`B&uild` from the pop-up menu.
The resultant library will be written to the
`C:\\BuildFolder\\tesseract-3.0x\\vs2008\\<ConfigurationName>` directory
where `<ConfigurationName>` is the same as the build configuration you
selected earlier. It is also copied to the `C:\\BuildFolder\\lib` folder
to make it easy to link your own applications to `libtesseract`.
The library is named as follows (for v3.02):
.. parsed-literal::
static libraries:
`libtesseract302-static.lib`
`libtesseract302-static-debug.lib`
DLLs:
`libtesseract302.lib` (import library)
`libtesseract302.dll`
`libtesseract302d.lib` (import library)
`libtesseract302d.dll`
4. Build the main tesseract OCR application by right-clicking the
:guilabel:`tesseract` project and choosing :menuselection:`B&uild`.
The resultant executable will be written to the
`C:\\BuildFolder\\tesseract-3.0x\\vs2008\\<ConfigurationName>` directory
where `<ConfigurationName>` is the same as the build configuration you
selected earlier. It is named as follows:
.. parsed-literal::
LIB_Release: `tesseract.exe`
LIB_Debug: `tesseractd.exe`
DLL_Release: `tesseract-dll.exe`
DLL_Debug: `tesseract-dlld.exe`
Testing `tesseract.exe`
=======================
It's usually better to make a separate directory to test
`tesseract.exe`. To run tesseract, you either need to make sure your
test directory contains the `tessdata` tesseract language data folder or
you set the ``TESSDATA_PREFIX`` environment variable to point to it. See
http://code.google.com/p/tesseract-ocr/wiki/ReadMe for important
details.
For example, you can use the following directory structure::
C:\BuildFolder\
include\
lib\
tesseract-3.02\
testing\
tessdata\
Copy your tesseract executable to `C:\\BuildFolder\\testing`. If you
built a DLL version then be sure to also copy the required DLLs to the
same directory (or add `C:\\BuildFolder\\lib` to your ``PATH`` --
However, this isn't really recommended).
For example, if you are trying to run `tesseractd.exe` then you'll need
to also copy the following to `C:\\BuildFolder\\testing`::
liblept168d.dll
libtesseract302d.dll
Copy a few test images to `C:\\BuildFolder\\testing` just to make it easy
to run test commands.
Test tesseract by doing something like the following::
tesseractd.exe eurotext.tif eurotext
This will create a file called `eurotext.txt` that will contain the
result of OCRing `eurotext.tif`.
Building the training applications
==================================
The training related applications are built using the following
projects::
ambiguous_words
classifier_tester
cntraining
combine_tessdata
dawg2wordlist
mftraining
shapeclustering
unicharset_extractor
wordlist2dawg
.. note::
Currently these applications can **ONLY** be built with the LIB_Debug
and LIB_Release configurations. If you try to use a DLL configuration
you'll get "undefined external symbol" errors.
To build one of the above training applications, simply right-click one
of the projects in the Solution Explorer, and choose
:menuselection:`B&uild` from the pop-up menu.
Alternatively, you can build :bi:`everything` in the Solution by
choosing :menuselection:`&Build --> &Build Solution` (:kbd:`Ctrl+Shift+B`)
from the menu bar.
See http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3 for
more information on using these applications.
.. _building-with-vc2008-express:
Building |Tesseractocr| with Visual C++ 2008 Express Edition
============================================================
The Solution file that comes with |Tesseractocr| was created with Visual
Studio 2008, and is compatible for the most part with the free `Visual
C++ 2008 Express Edition
<http://www.microsoft.com/visualstudio/en-us/products/2008-editions/express>`_. You
might, however, sometimes see the following error message::
Fatal error RC1015: cannot open include file 'afxres.h'
.. _version-resource:
The Solution uses resource files to set application and DLL properties
that are visible on Windows 7 when you right-click them in Windows
Explorer, choose :menuselection:`Properties`, and look at the
:guilabel:`Details` tab (the :guilabel:`Version` tab on Windows XP).
.. image:: images/dll_properties_details_tab.png
:align: center
:alt: Windows 7 Properties' Details Tab
Unfortunately, the Express Edition doesn't include the Resource
Editor. So in all resource files::
#include "afxres.h"
has to be changed to::
#include "windows.h"
If someone has used the VS2008 Resource Editor to change a `.rc` file
associated with an application or DLL and forgotten to make these
changes before checking the file in, you'll see the above "Fatal error"
message. Simply manually make the change to fix the error.

==================================
Maintaining the VS2008 directory
==================================
This section is geared towards project maintainers of the
`tesseract-3.0x\\vs2008` directory, rather than users of it.
Python 2.7.x (*not* 3.x) is required for this section. The recommended
version is the `latest from ActiveState
<http://www.activestate.com/activepython/downloads>`_.
.. _tesshelper:
The `tesshelper.py` Python script
=================================
`tesshelper.py` performs a number of useful maintenance related
operations on the `tesseract-3.0x\\vs2008` directory. To run it, first
open a Command Prompt window and navigate to the `<tesseract install
dir>\\vs2008` directory.
Then entering the following command::
python tesshelper.py --help
displays the following help message::
usage: tesshelper.py [-h] [--version] tessDir {compare,report,copy,clean} ...
positional arguments:
tessDir tesseract installation directory
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
Commands:
{compare,report,copy,clean}
compare compare libtesseract Project with tessDir
report report libtesseract summary stats
copy copy public libtesseract header files to includeDir
clean clean vs2008 folder of build folders and .user files
Examples:
Assume that tesshelper.py is in c:\buildfolder\tesseract-3.01\vs2008,
which is also the current directory. Then,
python tesshelper .. compare
will compare c:\buildfolder\tesseract-3.01 "library" directories to the
libtesseract Project
(c:\buildfolder\tesseract-3.01\vs2008\libtesseract\libtesseract.vcproj).
python tesshelper .. report
will display summary stats for c:\buildfolder\tesseract-3.01 "library"
directories and the libtesseract Project.
python tesshelper .. copy ..\..\include
will copy all "public" libtesseract header files to
c:\buildfolder\include.
python tesshelper .. clean
will clean the vs2008 folder of all build directories, and .user, .suo,
.ncb, and other temp files.
Generating the documentation
============================
The source files for the documentation you are currently reading are
written in `reStructuredText
<http://docutils.sourceforge.net/rst.html>`_ and processed with the
`Sphinx Python Documentation Generator
<http://sphinx.pocoo.org/index.html>`_.
To install Sphinx, go to your `<python.2.7.x install dir>\\scripts`
directory and just do::
easy_install -U Sphinx
which will download Sphinx and all its dependencies. [Note: This might
*not* install the Python Imaging Library. If not, then also do
``easy_install -U PIL`` or download it from `here
<http://www.pythonware.com/products/pil/>`__.]
To generate this |Tesseractocr| VS2008 documentation go to
`tesseract-3.0x\\vs2008\\Sphinx` and do::
make clean
make html
Which will create a number of items in
`tesseract-3.0x\\vs2008\\Sphinx\\_build\\html`.
Copy everything there to the distribution's `tesseract-3.0x\\vs2008\\doc`
folder, :bi:`except` for::
.buildinfo
objects.inv
.. _updating-vs2008-directory:
Updating the VS2008 directory for new releases of |Tesseractocr|
================================================================
1. Change the version number strings in
`tesseract-3.0x\\vs2008\\include\\tesseract_versionnumbers.vsprops`.
#. Change the version number in
`tesseract-3.0x\\vs2008\\port\\version.h`.
#. Open up a Command Prompt window, and do the following::
cd <tesseract-3.0x install dir>\vs2008
python tesshelper .. compare
This will list all added and missing items in the `<tesseract-3.0x install
dir>` directories that are used to build `libtesseract`. For the
newly added items ignore::
api\tesseractmain.cpp
api\tesseractmain.h
ccutil\scanutils.cpp
ccutil\scanutils.h
and for the newly missing items ignore::
training\commontraining.cpp
training\commontraining.h
training\tessopt.cpp
training\tessopt.h
#. Open up the `tesseract.sln` in Visual Studio 2008 (or Visual C++ 2008
Express Edition but see :ref:`this
<building-with-vc2008-express>` first).
a. In the Solution Explorer, rename the :guilabel:`libtesseract-3.0x`
Project to the correct version number to make it obvious which
version of |Tesseractocr| this Solution is for.
#. Remove the missing items from the :guilabel:`libtesseract-3.0x` Project.
#. Add the new items to the :guilabel:`libtesseract-3.0x` Project.
If there were a lot of new items, you can use the `newheaders.txt`
and `newsources.txt` files generated by running the
`tesshelper.py` script with the ``compare`` command. Close the
Solution, and then you can directly edit
`libtesseract\\libtesseract.vcproj` to add them to the appropriate
``<Filter> ... </Filter>`` section (either ``Header Files`` or
``Source Files``).
#. With the Solution closed, use a text editor to change all the
Project's `.rc` files to reflect the new version.
If you have a program like the *non-free* `PowerGrep
<http://www.powergrep.com/>`_, you can use it to change all the
`.rc` files in one fell swoop.
Alternatively, you can edit the Version resources within Visual
Studio 2008 (but *not* Visual C++ 2008 Express Edition) and then
manually make the changes mentioned :ref:`here
<building-with-vc2008-express>` afterwards.
.. _copying_a_project:
#. If a new training application was added (edit
`tesseract-3.0x\\training\\Makefile.am` and look at the
``bin_PROGRAMS`` variable to see the list), the easiest thing to do
is copy another existing training application Project and manually
change it.
For example, assuming the new training application is
called `new_trainer.exe`, with the Solution closed:
a. Copy the `ambiguous_words` directory to a new directory called
`new_trainer`.
#. Change the `new_trainer\\ambiguous_words.rc` filename to
`new_trainer\\new_trainer.rc`.
#. Change the `new_trainer\\ambiguous_words.vcproj` filename to
`new_trainer\\new_trainer.vcproj`.
#. Edit `new_trainer\\new_trainer.rc` and change all occurrences of
``ambiguous_words`` to ``new_trainer``.
Also change ``FileDescription`` to describe the new application.
#. Open up the |Tesseractocr| Solution file and right-click the
:guilabel:`Solution:'tesseract'` in the Solution Explorer. Choose
:menuselection:`A&dd --> &Existing Project...` from the context
menu and add the `new_trainer\\new_trainer.vcproj` you just
created.
#. Right-click the newly added Project, and choose
:menuselection:`Project Dependencie&s...`.
The :guilabel:`Project Dependencies` Dialog will open. Make sure
that `libtesseract30x` is checked. If you forget this step, Visual
Studio will not automatically link with `libtesseract` and
you'll get lots of "unresolved external symbol" errors.
This actually goes pretty fast. It should only take you a minute or
so to add a new application to the |Tesseractocr| Solution.
#. (Optional?) Edit `vs2008\\Sphinx\\versions.rst` and add a new entry
describing the changes made for this new version.
#. To make your working directory suitable for reposting back to the
|Tesseractocr| SVN repository, you need to ignore all the following:
+ All `LIB_Release`, `LIB_Debug`, `DLL_Release`, `DLL_Debug`
directories
+ All `.suo` files
+ All `.user` files
+ All `.ncb` files
+ `vs2008\\newheaders.txt`
+ `vs2008\\newsources.txt`
Optionally, the `tesshelper.py` script has the ``clean`` command
which will remove the above items. To run it, open a Command Prompt
window and then do::
cd <tesseract-3.0x install dir>\vs2008
python tesshelper .. clean
The script will respond with the following::
Are you sure you want to clean the
"C:\BuildFolder\tesseract-3.0x\vs2008" folder (Yes/No) [No]? yes
Only list the items to be deleted (Yes/No) [Yes]? no
You have to answer ``yes`` and then ``no`` to the prompts. Otherwise
either the script will just exit, or only list the items that will be
removed instead of actually removing them (which is a good thing to
try first just in case).

==========
Overview
==========
The recommended audience for this document are developers who want to
use Microsoft Visual Studio 2008 with `Tesseract-OCR
<http://code.google.com/p/tesseract-ocr/>`_. If you simply want to *run*
`tesseract` or its various language training applications, then see the
`ReadMe <http://code.google.com/p/tesseract-ocr/wiki/ReadMe>`_. You'll
find instructions there on how to download tesseract's Windows
installer.
|Tesseractocr| consists of:
+ `libtesseract` -- the static (or dynamic) library that does all the
actual work. As of February 2012 it consists of 260+ `C++` files
along with 290+ header files.
+ `tesseract.exe` -- the command-line OCR engine. It's built from a
single, small `C++` file that just calls functions in
`libtesseract`. There currently isn't very much documentation on how
to use `tesseract.exe`, but you can look at what's there in the
repository's `doc
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
subdirectory.
+ Language packs -- needed by `tesseract.exe` in order to recognize
particular languages.
.. _training-applications:
+ Language training applications -- used to teach `tesseract.exe` new
languages. Each has their own (very brief) man page in the `doc
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
subdirectory and include:
+ `ambiguous_words.exe` -- generate sets of words Tesseract is likely
to find ambiguous
+ `classifier_tester` -- tests a Tesseract character classifier on
data as formatted for training
+ `cntraining.exe` -- character normalization training
+ `combine_tessdata.exe` -- combine/extract/overwrite Tesseract data
+ `dawg2wordlist.exe` -- convert a Tesseract DAWG to a wordlist
+ `mftraining.exe` -- feature training
+ `shapeclustering.exe` -- shape clustering training
+ `unicharset_extractor.exe` -- extract unicharset from Tesseract
boxfiles
+ `wordlist2dawg.exe` -- convert a wordlist to a DAWG
Their use is described in the `TrainingTesseract3
<http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3>`_
Wiki page.
This document explains how to:
+ :doc:`Setup <setup>` the proper directory structure required to use
the supplied Visual Studio 2008 Solution
* :doc:`Build <building>` `libtesseract`, `tesseract.exe`, and the
training apps
* :doc:`Write <programming>` programs that link with `libtesseract`

=================================
Programming with `libtesseract`
=================================
To use `libtesseract` in your own application you need to include
|Leptonica|\ ’s `allheaders.h`, and |Tesseractocr|\ ’s `baseapi.h` and
`strngs.h`.
|Tesseractocr| uses `liblept` mainly for image I/O, but you can also use
any of |Leptonica|\ ’s *many* image processing functions on ``PIX``,
while at the same time calling ``TessBaseAPI`` methods. See the
`Leptonica documentation <http://tpgit.github.com/UnOfficialLeptDocs/>`_
for more details.
There doesn't seem to be any documentation on `api\\baseapi.h`, but it
has extensive comments. You can also look at the :ref:`APITest` and
:ref:`APIExamples` projects.
See the :ref:`APITest` project for an example of which compiler and
linker settings you need for various build configurations. The easiest
way to begin a new application is to just make a copy of the `APITest`
directory. See :ref:`this step <copying_a_project>` for detailed
instructions (skip the last step about adding :guilabel:`Project
Dependencies`).
If you want to manually set the required settings, then here's the list
of things to do:
1. Add the following :guilabel:`Preprocessor Definitions` when compiling
any files that include `baseapi.h` and you are linking with the
static library versions of `libtesseract`::
USE_STD_NAMESPACE
If you are linking with the DLL versions of `libtesseract` instead
add::
USE_STD_NAMESPACE;TESSDLL_IMPORTS;CCUTIL_IMPORTS;LIBLEPT_IMPORTS
#. Be sure to add the following to :guilabel:`Additional Include
Directories`::
C:\BuildFolder\include
C:\BuildFolder\include\leptonica
C:\BuildFolder\include\tesseract or
<tesseract-3.0x dir> (all its sub-directories that contain header files)
#. Add `C:\\BuildFolder\\lib` to your :guilabel:`Additional Library
Directories`.
#. In the `C:\\BuildFolder\\include` directory are two Visual Studio
Property Sheet files::
tesseract_versionnumbers.vsprops
leptonica_versionnumbers.vsprops
Using `tesseract_versionnumbers.vsprops` (which automatically inherits
`leptonica_versionnumbers.vsprops`) can make it easier to specify the
libraries you need to import. For example, when creating a staticly
linked debug executable you can say::
zlib$(ZLIB_VERSION)-static-mtdll-debug.lib
libpng$(LIBPNG_VERSION)-static-mtdll-debug.lib
libjpeg$(LIBJPEG_VERSION)-static-mtdll-debug.lib
giflib$(GIFLIB_VERSION)-static-mtdll-debug.lib
libtiff$(LIBTIFF_VERSION)-static-mtdll-debug.lib
liblept$(LIBLEPT_VERSION)-static-mtdll-debug.lib
libtesseract$(LIBTESS_VERSION)-static-debug.lib
to make your application less dependent on library version numbers.
To add the Property Sheet to a Project, open its :guilabel:`Properties
Pages` Dialog, and set the :guilabel:`Configuration Properties |
General | Inherited Project Property Sheets` item to::
..\..\..\include\tesseract_versionnumbers.vsprops
Choosing :menuselection:`&View --> Oth&er Windows --> Property
&Manager` from the menubar will let you see the Properties attached
to each Project's configurations.
.. note::
The DLL versions of |libtess| currently only export the
``TessBaseAPI`` C++ class from `baseapi.h`, there is no C function
interface yet.
.. note::
The DLL versions of `libtesseract` currently only export the
``TessBaseAPI`` and ``STRING`` classes. In theory, all you need is
are those classes. However, if you find yourself having to manipulate
other "internal" tesseract objects then you currently have to link
with the **static library** versions of `libtesseract`.
.. warning::
The Release versions of |liblept|, by design, *never* print out any
possibly helpful messages to the console. Therefore, it is highly
recommended that you do your initial development using the Debug
versions of |liblept|. See `Compile-time control over stderr output
<http://tpgit.github.com/UnOfficialLeptDocs/leptonica/README.html#compile-time-control-over-stderr-output>`_
for details.
<<<Need to add the URL of the zip file that contains include & lib
directory contents for those people who don't want to build libtesseract
themselves>>>
Debugging Tips
==============
Before debugging programs written with `libtesseract`, you should first
download the latest Leptonica sources (currently
`leptonica-1.68.tar.gz`) and VS2008 source package (`vs2008-1.68.zip`)
from:
+ http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68.tar.gz
+ http://code.google.com/p/leptonica/downloads/detail?name=vs2008-1.68.zip
Unpack them to `C:\\BuildFolder` to get the following directory structure::
C:\BuildFolder\
include\
lib\
leptonica-1.68\
vs2008\
tesseract-3.02\
vs2008\
testing\
tessdata\
(see `Building the liblept library
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-liblept.html>`_
for more information)
|Tesseractocr| uses |Leptonica| "under the hood" for all (most? some?)
of its image processing operations. Having the source available (and
compiling it in debug mode) will make it easier to see what's really
going on.
You might want to add
`C:\\BuildFolder\\leptonica-1.68\\vs2008\\leptonica.vcproj` and
`C:\\BuildFolder\\tesseract-3.02\\vs2008\\libtesseract\\libtesseract.vcproj`
to your solution by right-clicking it and choosing :menuselection:`A&dd -->
&Existing Project...`. This seems to make VS2008's Intellisense `work
better
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-other-programs.html#intellisense-and-liblept>`_
when finding "external" source files.
Definitely create a ``TESSDATA_PREFIX``x environment variable so that it
contains the absolute path of the directory that contains the
``tessdata`` directory. Otherwise you'll have to put a ``tessdata``
directory in every temporary build folder which quickly becomes painful
(especially since tessdata has gotten very big --- 600MB!).
.. _APITest:
APITest Sample
==============
The :guilabel:`APITest` Solution contains the minimal settings needed to
link with `libtesseract`. It demonstrates the typical situation, where
the "external" application's source files reside *outside* of the
`tesseract-3.0x` directory tree.
To build the `vs2008\\APITest` Solution, first copy it to your
`C:\\BuildFolder` directory. This should now look like::
C:\BuildFolder\
include\
leptonica\
tesseract\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll-debug.lib
libjpeg8c-static-mtdll.lib
liblept168-static-mtdll-debug.lib
liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtesseract302.dll
libtesseract302.lib
libtesseract302d.dll
libtesseract302d.lib
libtesseract302-static.lib
libtesseract302-static-debug.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
tesseract-3.02\
APITest\
baseapitester\
baseapitester.cpp
baseapitester.rc
baseapitester.vcproj
resource.h
stdafx.cpp
stdafx.h
targetver.h
APITest.sln
The :guilabel:`APITest` contains just the :guilabel:`baseapitester`
project. This was created using the VS2008 :guilabel:`Win32 Console
Application` Project Wizard and then just copying most of
`tesseractmain.cpp` and making minor edits. Its settings correctly refer
to the "public" `include` and `lib` directories using relative paths.
It assumes that the `C:\\BuildFolder\\include` directory has been
properly setup. See :ref:`this <copying-headers>` for more details.
The `C:\\BuildFolder\\lib` directory will automatically get
`libtesseract` copied to it whenever it is built.
The `include\\tesseract_versionnumbers.vsprops` Property Sheet is used
to avoid explicit library version number dependencies. Precompiled
headers are used. :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug` build configurations

|Tesseractocr| preprocessor definitions
=======================================
``HAVE_CONFIG_H``
Only defined when building under Linux. This causes the inclusion of
`config_auto.h`, which is only auto-generated during the `./configure`
process and thus *not* visible on Windows.
This is what sets the ``VERSION`` macro (and lots of other
configuration related macros).
``TESSDLL_EXPORTS``
Only used when *building* DLL versions of |libtess|.
``TESSDLL_IMPORTS``
Should be defined when building apps that link to a DLL version of
|libtess|. Used as follows in `baseapi.h`::
#ifdef TESSDLL_EXPORTS
#define TESSDLL_API __declspec(dllexport)
#elif defined(TESSDLL_IMPORTS)
#define TESSDLL_API __declspec(dllimport)
#else
#define TESSDLL_API
#endif
If you don't define this then you'll get "undefined external symbol"
errors.
``TESSDLL_API``
Used to mark classes for export (visibility) in DLL versions of
|libtess|. Currently *only* used with the ``TestBaseAPI`` class.
``CCUTIL_EXPORTS``
Only used when *building* DLL versions of |libtess|.
``CCUTIL_IMPORTS``
Should be defined when building apps that link to a DLL version of
|libtess|. Used as follows in `strngs.h`::
#ifdef CCUTIL_EXPORTS
#define CCUTIL_API __declspec(dllexport)
#elif defined(CCUTIL_IMPORTS)
#define CCUTIL_API __declspec(dllimport)
#else
#define CCUTIL_API
#endif
If you don't define this then you'll get "undefined external symbol STRING"
errors.
``LIBLEPT_IMPORTS``
Should be defined when building apps that link to a DLL version of
|Leptonica|. Used as follows in environ.h::
#if defined(LIBLEPT_EXPORTS) || defined(LEPTONLIB_EXPORTS)
#define LEPT_DLL __declspec(dllexport)
#elif defined(LIBLEPT_IMPORTS) || defined(LEPTONLIB_IMPORTS)
#define LEPT_DLL __declspec(dllimport)
#else
#define LEPT_DLL
#endif
If you don't define this then you'll get "undefined external symbol"
errors.
``USE_STD_NAMESPACE``
Causes the following to be done::
#ifdef USE_STD_NAMESPACE
using std::string;
using std::vector;
#endif
``_WIN32``
Used to indicate that the build target is Windows 32-bit or
64-bit (``WIN32`` and ``WINDOWS`` are also added by the New Project
Wizards).
See `C/C+ Preprocessor Reference | The Preprocessor | Macros |
Predefined Macros
<http://msdn.microsoft.com/en-us/library/b0084kay(v=vs.90).aspx>`_ for
the complete list for Visual Studio 2008.
``_MSC_VER``
Used to check specifically for building with the VC++ compiler (as
opposed to the MinGW gcc compiler).
``_USRDLL``
Only defined when building the DLL versions of `libtesseract`.
``_MBCS``
Automatically defined when :guilabel:`Configuration Properties |
General | Character Set` is set to :guilabel:`Use Multi-Byte
Character Set`.
``DLLSYM``
`Obsolete
<http://groups.google.com/group/tesseract-dev/msg/5e0f7f7fab27b463>`_

===========================
Setting up |Tesseractocr|
===========================
The Visual Studio 2008 Solutions included with |Tesseractocr|, rely on
*relative paths* to reference files and directories --- including
locations that are *outside* of the `tesseract-3.0x` tree. It is
therefore vitally important to correctly set up the directories for the
various components. This section describes how to do this.
.. _directory-setup:
Initial "Build" directory setup
===============================
First create an empty directory where you will unpack all the required
downloads. Assume you call this directory `C:\\BuildFolder`.
.. _download-leptonica:
1. Download the |Leptonica| 1.68 pre-built binary package
(`leptonica-1.68-win32-lib-include-dirs.zip`) from:
http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68-win32-lib-include-dirs.zip
and unpack it to `C:\\BuildFolder`.
2. |Leptonica|, even on Windows as of v1.68, still requires a few unix
utilities (like `rm`, `diff`, `sleep`). The easiest way to deal with
this is to follow the instructions at `Installing Cygwin coreutils
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html>`_.
At this point, if all you want to do is link with `libtesseract` you can
`download <http://code.google.com/p/tesseract-ocr/downloads/list>`_ the
file that just contains the "public" |Tesseractocr| headers along with
the precompiled library binaries for Windows. Unpack it to
`C:\\BuildFolder` and you'll now have::
C:\BuildFolder\
include\
leptonica\
tesseract\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll-debug.lib
libjpeg8c-static-mtdll.lib
liblept168-static-mtdll-debug.lib
liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtesseract302.dll
libtesseract302.lib
libtesseract302d.dll
libtesseract302d.lib
libtesseract302-static.lib
libtesseract302-static-debug.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
and you can skip the rest of this page and go directly to
:doc:`programming`.
The recommended action, however, is to download the |Tesseractocr|
sources and build them yourself. Therefore...
3. Download the |Tesseractocr| Visual Studio 2008 source files from the
`downloads page
<http://code.google.com/p/tesseract-ocr/downloads/list>`_. If, for
example, you'd like to build v3.02 you would use the following link:
http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-3.02-vs2008.zip
Unpack the file to `C:\\BuildFolder`
You would now have the following directory structure::
C:\BuildFolder\
include\
leptonica\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll-debug.lib
libjpeg8c-static-mtdll.lib
liblept168-static-mtdll-debug.lib
liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib

tesseract.sln
tesshelper.py
4. Download the |Tesseractocr| source files for the same version as the
VS2008 files you just unpacked. In this case, the proper link would
be:
http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-3.02.tar.gz
Unpack the file to `C:\\BuildFolder`
This will add a bunch of directories to your already existing
`C:\\BuildFolder\\tesseract-3.0x` directory. You should now have (for
v3.02)::
C:\BuildFolder\
include\
leptonica\
lib\
tesseract-3.02\
api\
ccmain\
ccstruct\
ccutil\
classify\
config\
contrib\

dict\
doc\
image\
java\
image\
neural_networks\
tessdata\
testing\
textord\
training\
viewer\
vs2008\
wordrec\
.. _copying-headers:
If you are planning on writing applications that link with
|Tesseractocr|, and you don't want to add all the `tesseract-3.0x`
directories to your project's list of ``include`` directories, then do
this additional step:
5. Copy all the required headers to the "public" include folder.
If you already have a `C:\\BuildFolder\\include\\tesseract`
directory you should delete it in case some of the files have been
removed.
Then use the python `tess-helper.py` script to copy (possibly updated
versions of) the required headers by doing::
cd C:\BuildFolder\tesseract-3.02\vs2008
python tesshelper.py .. copy ..\..\include
See :ref:`tesshelper` for more details.
You are now ready to :doc:`build <building>` |Tesseractocr| using Visual
Studio 2008.
.. _using-latest-sources:
Using the latest |Tesseractocr| sources
=======================================
If you'd like to try the absolute latest version of |Tesseractocr|,
here's how to download the source files from its SVN repository:
1. Follow Steps 1 and 2 :ref:`above <directory-setup>`.
#. `Checkout <http://code.google.com/p/tesseract-ocr/source/checkout>`_
the |Tesseractocr| sources to a directory on your computer. This
directory should :bi:`not` be `C:\\BuildFolder`!
If you are unfamiliar with `SVN <http://subversion.apache.org/>`_,
the easiest way to do this is to first download and install
`TortoiseSVN <http://tortoisesvn.net/>`_ and then:
a. Right-click the (empty) directory where you want the working copy
and choose :menuselection:`SVN Chec&kout...` from
the pop-up menu.
#. Enter ``http://tesseract-ocr.googlecode.com/svn/trunk/`` for
:guilabel:`&URL of repository`. You can keep all the other
settings at their defaults.
.. image:: images/tortoisesvn_checkout.png
:align: center
:alt: TortoiseSVN Checkout Dialog Box
#. Click the :guilabel:`&OK` button to commence downloading the
|Tesseractocr| sources to your computer. This might take a while as
the language data in the `tessdata` directory is quite large. As
of February 2012, about 335MB needs to be transferred for the
initial checkout. The total size of the resulting working copy is
about 1.2GB.
#. Keeping your working copy up to date after this is as simple as
right-clicking its directory and choosing :menuselection:`SVN
&Update`. Unlike the initial checkout, this will usually finish
very quickly.
#. Copy the :bi:`contents` of your working directory, except for the
`tessdata` directory, to `C:\\BuildFolder\\tesseract-3.0x`, where
``x`` should probably be the latest stable release + ``alpha``,
``beta``, etc.
#. Optionally, follow Step 5 from :ref:`above <copying-headers>`.
#. You'll probably want to set an environment varible named
``TESSDATA_PREFIX`` to point at your working copy directory (since
that now contains the latest `tessdata` directory).
#. If someone hasn't already done so, you have to proceed to
:ref:`updating-vs2008-directory`. You can skip all the steps that
relate to updating the version number. Otherwise, depending on how
many changes have been made since the last stable release, you may
have little or no work to do.

Handy free tools
==================
`TortoiseSVN <http://tortoisesvn.net/>`_
----------------------------------------
The |Tesseractocr| source lives in an SVN repository at `Google Code
<http://code.google.com/p/tesseract-ocr/source/checkout>`_, so to
:ref:`build the latest versions <using-latest-sources>` you'll need to
know SVN. For newcomers (or not), TortoiseSVN (http://tortoisesvn.net/)
is a great alternative to the SVN command line interface.
"TortoiseSVN is an easy-to-use SCM / source control software for
Microsoft Windows and possibly the best standalone Apache Subversion
client there is. It is implemented as a Windows shell extension, which
makes it integrate seamlessly into the Windows explorer. Since it's not
an integration for a specific IDE you can use it with whatever
development tools you like."
`JP Software TCC/LE <http://jpsoft.com/tccle_cmd_replacement.html>`_
--------------------------------------------------------------------
Instead of using Windows' plain old Command Prompt window --- and less
intimidating than using the bash shell from `cygwin
<http://cygwin.com/>`_ or `MSYS <http://mingw.org/wiki/msys>`_ --- the
"TCC/LE - Windows CMD Replacement Command Console" by JP Software is
definitely worth trying. It is available at
http://jpsoft.com/tccle_cmd_replacement.html.
For example, to look for all the settable options in |Tesseractocr|,
try::
C:\BuildFolder\tesseract-3.02\
ffind /s/v/c/t"_MEMBER" *.cpp | list/s
and you'll get something that looks like this in the `list` viewer::
---- C:\BuildFolder\tesseract-3.02\ccmain\tesseractclass.cpp
: BOOL_MEMBER(tessedit_resegment_from_boxes, false,
BOOL_MEMBER(tessedit_resegment_from_line_boxes, false,
BOOL_MEMBER(tessedit_train_from_boxes, false,
BOOL_MEMBER(tessedit_make_boxes_from_boxes, false,
BOOL_MEMBER(tessedit_dump_pageseg_images, false,
...
double_MEMBER(segsearch_max_char_wh_ratio, 2.0,
double_MEMBER(segsearch_max_fixed_pitch_char_wh_ratio, 2.0,
BOOL_MEMBER(save_alt_choices, false,
413 lines in 7 files
(Press the :kbd:`Escape` key to exit the `list` viewer).
The equivalent(?) Linux incantation, copied and slightly modified from
the grep info, is::
find . -name '*.cpp' -print0 | xargs -0r grep -H '_MEMBER' | less
Note: You can also do this directly in Visual Studio 2008, by choosing
:menuselection:`&Edit --> &Find and Replace --> F&ind in Files`
(:kbd:`Ctrl+Shift+F`), so maybe this wasn't the best example:
.. image:: images/find_in_files.png

`Cygwin <http://cygwin.com/>`_
------------------------------
"`Cygwin <http://cygwin.com/>`_ is a collection of tools which provide a
Linux look and feel environment for Windows."
|Leptonica| actually still requires a few unix utilities (like `rm`,
`diff`, `sleep`) for some operations and might silently fail if it they
not present (as of v1.68). The easiest way to deal with this is to
`install Cygwin
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html>`_
or MSYS (see the next section).
`MSYS <http://mingw.org/wiki/msys>`_
------------------------------------
"`MSYS <http://mingw.org/wiki/msys>`_ is a collection of GNU utilities
such as bash, make, gawk and grep to allow building of applications and
programs which depend on traditionally UNIX tools to be present. It is
intended to supplement MinGW and the deficiencies of the cmd shell."
WinDiff
-------
An important phase of testing `tesseract` is checking how its output
compares to previous runs (or ground-truth files). A visual diff program
can make that easier.
Microsoft's WinDiff doesn't seem to come with Visual Studio
anymore. However it can still be downloaded from `Grig Software
<http://www.grigsoft.com/download-windiff.htm>`_ (without having to get
all the other stuff in the `Windows XP Service Pack 2 Support Tools
<http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=18546>`_.
Other options are `KDiff3 <http://kdiff3.sourceforge.net/>`_ and
`ExamDiff <http://www.prestosoft.com/edp_examdiff.asp>`_ (`ExamDiff Pro
<http://www.prestosoft.com/edp_examdiffpro.asp>`_ is also recommended
but it's not free).
KDiff3 doesn't seem to correctly auto-detect UTF-8 encodings so choose
:menuselection:`&Settings --> &Configure KDiff3...` from the menubar and
set the :guilabel:`Regional Settings` tab as follows:
.. image:: images/kdif3_settings.png
:align: center
:alt: KDiff3 Regional Settings
Also on the :guilabel:`Integration` tab, make sure that :guilabel:`Quit
also via Escape key` is turned on (checked). Since IrfanView also quits
when you press the :kbd:`Esc` key, this just makes it easy to dismiss
both applications with the same key.
Here is KDiff3 showing the (slight) difference in OCR results after
deskewing a grayscale image:
.. figure:: images/sample_diff.png
:height: 512
:align: center
:alt: Diff in OCR after deskewing image
:target: _images/sample_diff.png
`Click for larger image <_images/sample_diff.png>`__
`IrfanView <http://www.irfanview.com/>`_
----------------------------------------
You need some program to view the images you are trying to OCR and since
|Leptonica| uses IrfanView (http://www.irfanview.com/) to `automatically
display images <http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-irfanview.html>`_,
you might as well use it also.
"IrfanView is a very fast, small, compact and innovative FREEWARE (for
non-commercial use) graphic viewer for Windows 9x, ME, NT, 2000, XP,
Vista, Windows 7."
Pressing the :kbd:`I` key while viewing an image with IrfanView, will
bring up a dialog box that shows most of its important properties (like
bits/pixel and DPI).
`Aware Systems AsTiffTagViewer <http://www.awaresystems.be/imaging/tiff/astifftagviewer.html>`_
-----------------------------------------------------------------------------------------------
This utility, available at
http://www.awaresystems.be/imaging/tiff/astifftagviewer.html, let's you
easily determine TIFF image file properties.
"Whenever a customer reports your software doesn't handle this or that
particular TIFF, use AsTiffTagViewer and discover why."
`Dependency Walker <http://dependencywalker.com/>`_
---------------------------------------------------
If you're having problems with missing module runtime errors, the
Dependency Walker (http://dependencywalker.com/) usually can help track
down the problem.
"Dependency Walker is also very useful for troubleshooting system errors
related to loading and executing modules. Dependency Walker detects many
common application problems such as missing modules, invalid modules,
import/export mismatches, circular dependency errors, mismatched machine
types of modules, and module initialization failures."
You probably want the 32-bit version even if you are running on a
Windows 64-bit platform, because the current VS2008 Solution for
|Tesseractocr| by default builds a 32-bit app. From the `FAQ
<http://dependencywalker.com/faq.html>`_
"There are 32-bit and 64-bit versions Dependency Walker. All versions
are capable or opening 32-bit and 64-bit modules. However, there are
major advantages to using the 32-bit Dependency Walker to process 32-bit
modules and the 64-bit Dependency Walker to process 64-bit modules.
This is especially true when running on a 64-bit version of Windows,
which allows execution of both 32-bit and 64-bit programs. The 32-bit
subsystem on 64-bit Windows (known as "WOW64") has its own private
registry, "AppPaths", "KnownDlls", system folders, and manifest
processing. Only the 32-bit version of Dependency Walker can access
this 32-bit environment, which is needed to accurately process a 32-bit
module. Likewise, only the 64-bit version of Dependency Walker can
fully access the 64-bit environment, so it should always be used for
processing 64-bit modules."

The above image shows Dependency Walker used on
`tesseract-dlld.exe`. The panes show the `DLL`\ s that it is dependent
on, the methods it actually uses from `libtesseract302d.dll`, and all
the exported methods from `libtesseract302d.dll`. Using this it's easy
to see that only the ``TessBaseAPI`` and ``STRING`` classes are exported
as mentioned in :doc:`programming`.

-------------------------------------------------------------------------------------------
Another essential program to help figure out what your program is doing
is Process Explorer
(http://technet.microsoft.com/en-us/sysinternals/bb896653).
"The unique capabilities of Process Explorer make it useful for tracking
down DLL-version problems or handle leaks, and provide insight into the
way Windows and applications work."
`VMware Player <http://www.vmware.com/products/player/>`_
---------------------------------------------------------
VMware Player (http://www.vmware.com/products/player/) can be used to
install, for example, `Ubuntu 11.10 <http://www.ubuntu.com/>`_ in a
virtual machine on Windows and see how the other half lives. It also
helps when trying to figure out if the Windows version of `tesseract`
acts the same way as the "original" version.
"VMware Player is the easiest way to run multiple operating systems at
the same time on your PC. With its user-friendly interface, VMware
Player makes it effortless for anyone to try out Windows 8 developer
release, Windows 7, Chrome OS or the latest Linux releases, or create
isolated virtual machines to safely test new software and surf the Web."

Version Notes
===============
3.02 -- February ??, 2012
=========================
+ Created a completely new Visual Studio 2008 solution from scratch.
+ Added 64 new source files and removed the following deleted files
(relative to v3.01):
+ ccutil\memblk.cpp
+ ccutil\memblk.h
+ ccutil\memryerr.h
+ wordrec\pieces.h
+ wordrec\tally.cpp
+ wordrec\tally.h
+ Created :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug` build
configurations.
+ Created a single `libtesseract` library and removed generation of the
twelve sub-libraries.
+ Used references to `leptonica_versionnumbers.vsprops` and
`tesseract_versionnumbers.vsprops` Property Sheets, which define
version number "user macros", in all Visual Studio Projects. These are
also copied to `C:\\BuildFolder\\include`, so you can refer to them in
your own projects. By using the new ``*_VERSION`` macros, you'll be
isolated from worrying about version number changes in the library
filenames.
See :ref:`APITest's <APITest>` :ref:`LIB_Release <apitest-lib-release>` Linker
:guilabel:`Additional Dependencies` settings for an example of what
this looks like in practice.
See |Leptonica|\ ’s explanation `About version numbers in library
filenames
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers>`_
for more details.
+ Added a :ref:`Version Resource <version-resource>` to all DLLs and
applications.
+ Removed inclusion of the |Leptonica| libraries. They now have to be
:ref:`downloaded separately <download-leptonica>`.
+ Changed to a :ref:`Build directory structure <directory-setup>` that
is compatible with |Leptonica| and allows the building of
|Tesseractocr|\ -based applications using only the `include` and `lib`
directories.
+ The `libtesseract` libraries are now named as follows:
static libraries:
+ libtesseract302-static.lib
+ libtesseract302-static-debug.lib
DLLs:
+ libtesseract302.lib (import library)
+ libtesseract302.dll
+ libtesseract302d.lib (import library)
+ libtesseract302d.dll
+ Used compiler and linker settings based on the |Leptonica| `VS2008
Developer package
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/index.html>`_.
+ Removed all preprocessor defines of ``__MSW32__`` which is no longer
needed.
+ Removed `vs2008\include\stdint.h` which is no longer required to build
|liblept|.
+ Removed `vs2008\include\inttypes.h` which isn't needed to build
|liblept|.
+ Turned off the following compiler warnings::
/wd4005: 'snprintf' : macro redefinition
/wd4018 'expression' : signed/unsigned mismatch
/wd4099 type name first seen using 'class' now seen using 'struct'
/wd4244 conversion from 'double' to 'float', possible loss of data
/wd4267 conversion from 'size_t' to 'type', possible loss of data
/wd4305 truncation from 'type1' to 'type2'
/wd4355 'this' : used in base member initializer list
/wd4566 character represented by universal-character-name x cannot
be represented in the current code page
/wd4800 forcing value to bool 'true' or 'false' (performance warning)
/wd4996 'function': was declared deprecated
+ Used the "C7 Compatible" Debug Information (/Z7) compiler switch,
which puts the debugging information in the .obj files. That way we
don't have to worry about also supplying `.pdb` files. See `/Z7,
/Zi, /ZI (Debug Information Format)
<http://msdn.microsoft.com/en-us/library/958x11bc(VS.90).aspx>`_ for
more information.
+ Added Projects for the following new :ref:`training applications
<training-applications>`:
+ ambiguous_words
+ classifier_tester
+ dawg2wordlist
+ shapeclustering
+ Moved `mathfix.h` from `vs2008\\include` to the `vs2008\\port`
directory.
+ Removed Visual Studio 2010 support. See :doc:`vs2010-notes` for the
rationale.
+ Created a python script called :ref:`tesshelper.py <tesshelper>`, that
eases some maintenance tasks related to releasing future VS2008
Solutions.
+ The list of "public" header files that are required to build
"external" applications is now limited to the following 13 files::
api\apitypes.h
api\baseapi.h
ccmain\thresholder.h
ccstruct\publictypes.h
ccutil\errcode.h
ccutil\fileerr.h
ccutil\host.h
ccutil\memry.h
ccutil\platform.h
ccutil\serialis.h
ccutil\strngs.h
ccutil\tesscallback.h
ccutil\unichar.h

Using Visual Studio 2010
==========================
There currently isn't an analogous `VS2010` sub-directory for
|Tesseractocr|. However, you should be able to adapt the instructions at
http://tpgit.github.com/UnOfficialLeptDocs/vs2008/vs2010-notes.html to
convert the VS2008 solution.

/*
* sidebar.js
* ~~~~~~~~~~
*
* This script makes the Sphinx sidebar collapsible.
*
* .sphinxsidebar contains .sphinxsidebarwrapper. This script adds
* in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
* used to collapse and expand the sidebar.
*
* When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
* and the width of the sidebar and the margin-left of the document
* are decreased. When the sidebar is expanded the opposite happens.
* This script saves a per-browser/per-session cookie used to
* remember the position of the sidebar among the pages.
* Once the browser is closed the cookie is deleted and the position
* reset to the default (expanded).

<h1>Building <strong>Tesseract-OCR</strong><a class="headerlink" href="#building-tesseractocr" title="Permalink to this headline"></a></h1>
<p>The Visual Studio 2008 Solution for <strong>Tesseract-OCR</strong> builds:</p>
<ul>
<li><p class="first"><span class="filesystem">libtesseract</span></p>
</li>
<li><p class="first"><span class="filesystem">tesseract.exe</span></p>
</li>
<li><p class="first">9 training applications (for v3.02)</p>
</li>
</ul>
<p>Unlike earlier Solutions only a single <span class="filesystem">libtesseract</span> library is
generated &#8212; the twelve projects matching the twelve source subfolders
have been abandoned. They were deemed too complicated since they were
never (rarely?) used by themselves, but only along with the entire
library.</p>
<p>In addition, <span class="filesystem">libtesseract</span> and <span class="filesystem">tesseract.exe</span> can be built using four
configurations: <em class="guilabel">LIB_Release</em>, <em class="guilabel">LIB_Debug</em>,
<em class="guilabel">DLL_Release</em>, and <em class="guilabel">DLL_Debug</em>.</p>
<p>Two Visual Studio Property Sheets, <span class="filesystem">leptonica_versionnumbers.vsprops</span>
and <span class="filesystem">tesseract_versionnumbers.vsprops</span>, are employed to isolate the
Solution from changes in dependency version numbers (and isolate
dependent Solutions). See <a class="reference internal" href="programming.html#apitest"><em>APITest&#8217;s</em></a> <a class="reference internal" href="programming.html#apitest-lib-release"><em>LIB_Release</em></a> Linker <em class="guilabel">Additional Dependencies</em>
settings for an example of what this looks like in practice. See
<strong>Leptonica</strong>’s explanation <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers">About version numbers in library filenames</a>

<h2>Testing <span class="filesystem">tesseract.exe</span><a class="headerlink" href="#testing-tesseract-exe" title="Permalink to this headline"></a></h2>
<p>It&#8217;s usually better to make a separate directory to test
<span class="filesystem">tesseract.exe</span>. To run tesseract, you either need to make sure your
test directory contains the <span class="filesystem">tessdata</span> tesseract language data folder or
you set the <tt class="docutils literal"><span class="pre">TESSDATA_PREFIX</span></tt> environment variable to point to it. See
<a class="reference external" href="http://code.google.com/p/tesseract-ocr/wiki/ReadMe">http://code.google.com/p/tesseract-ocr/wiki/ReadMe</a> for important
details.</p>
<p>For example, you can use the following directory structure:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\
include\
lib\
tesseract-3.02\
testing\
tessdata\
</pre></div>
</div>
<p>Copy your tesseract executable to <span class="filesystem">C:\BuildFolder\testing</span>. If you
built a DLL version then be sure to also copy the required DLLs to the
same directory (or add <span class="filesystem">C:\BuildFolder\lib</span> to your <tt class="docutils literal"><span class="pre">PATH</span></tt> &#8211;
However, this isn&#8217;t really recommended).</p>
<p>For example, if you are trying to run <span class="filesystem">tesseractd.exe</span> then you&#8217;ll need
to also copy the following to <span class="filesystem">C:\BuildFolder\testing</span>:</p>
<div class="highlight-none"><div class="highlight"><pre>liblept168d.dll
libtesseract302d.dll
</pre></div>
</div>
<p>Copy a few test images to <span class="filesystem">C:\BuildFolder\testing</span> just to make it easy
to run test commands.</p>
<p>Test tesseract by doing something like the following:</p>
<div class="highlight-none"><div class="highlight"><pre>tesseractd.exe eurotext.tif eurotext
</pre></div>
</div>
<p>This will create a file called <span class="filesystem">eurotext.txt</span> that will contain the
result of OCRing <span class="filesystem">eurotext.tif</span>.</p>
</div>
<div class="section" id="building-the-training-applications">

<p>The Solution file that comes with <strong>Tesseract-OCR</strong> was created with Visual
Studio 2008, and is compatible for the most part with the free <a class="reference external" href="http://www.microsoft.com/visualstudio/en-us/products/2008-editions/express">Visual
C++ 2008 Express Edition</a>. You
might, however, sometimes see the following error message:</p>
<div class="highlight-none"><div class="highlight"><pre>Fatal error RC1015: cannot open include file &#39;afxres.h&#39;
</pre></div>
</div>
<p id="version-resource">The Solution uses resource files to set application and DLL properties
that are visible on Windows 7 when you right-click them in Windows
Explorer, choose <em class="menuselection">Properties</em>, and look at the
<em class="guilabel">Details</em> tab (the <em class="guilabel">Version</em> tab on Windows XP).</p>
<blockquote>
<div><img alt="Windows 7 Properties' Details Tab" class="align-center" src="_images/dll_properties_details_tab.png" />
</div></blockquote>
<p>Unfortunately, the Express Edition doesn&#8217;t include the Resource
Editor. So in all resource files:</p>
<div class="highlight-none"><div class="highlight"><pre>#include &quot;afxres.h&quot;
</pre></div>
</div>
<p>has to be changed to:</p>
<div class="highlight-none"><div class="highlight"><pre>#include &quot;windows.h&quot;
</pre></div>
</div>
<p>If someone has used the VS2008 Resource Editor to change a <span class="filesystem">.rc</span> file
associated with an application or DLL and forgotten to make these
changes before checking the file in, you&#8217;ll see the above &#8220;Fatal error&#8221;
message. Simply manually make the change to fix the error.</p>

<p><span class="filesystem">tesshelper.py</span> performs a number of useful maintenance related
operations on the <span class="filesystem">tesseract-3.0x\vs2008</span> directory. To run it, first
open a Command Prompt window and navigate to the <span class="filesystem">&lt;tesseract install
dir&gt;\vs2008</span> directory.</p>
<p>Then entering the following command:</p>
<div class="highlight-none"><div class="highlight"><pre>python tesshelper.py --help
</pre></div>
</div>
<p>displays the following help message:</p>
<div class="highlight-none"><div class="highlight"><pre>usage: tesshelper.py [-h] [--version] tessDir {compare,report,copy,clean} ...
positional arguments:
tessDir tesseract installation directory
optional arguments:
-h, --help show this help message and exit
--version show program&#39;s version number and exit
Commands:
{compare,report,copy,clean}
compare compare libtesseract Project with tessDir
report report libtesseract summary stats
copy copy public libtesseract header files to includeDir
clean clean vs2008 folder of build folders and .user files
Examples:
Assume that tesshelper.py is in c:\buildfolder\tesseract-3.01\vs2008,
which is also the current directory. Then,
python tesshelper .. compare
will compare c:\buildfolder\tesseract-3.01 &quot;library&quot; directories to the
libtesseract Project
(c:\buildfolder\tesseract-3.01\vs2008\libtesseract\libtesseract.vcproj).
python tesshelper .. report
will display summary stats for c:\buildfolder\tesseract-3.01 &quot;library&quot;
directories and the libtesseract Project.
python tesshelper .. copy ..\..\include
will copy all &quot;public&quot; libtesseract header files to
c:\buildfolder\include.
python tesshelper .. clean
will clean the vs2008 folder of all build directories, and .user, .suo,
.ncb, and other temp files.

<li><p class="first">With the Solution closed, use a text editor to change all the

<p>If you have a program like the <em>non-free</em> <a class="reference external" href="http://www.powergrep.com/">PowerGrep</a>, you can use it to change all the
<span class="filesystem">.rc</span> files in one fell swoop.</p>
<p>Alternatively, you can edit the Version resources within Visual
Studio 2008 (but <em>not</em> Visual C++ 2008 Express Edition) and then
manually make the changes mentioned <a class="reference internal" href="building.html#building-with-vc2008-express"><em>here</em></a> afterwards.</p>

<span class="filesystem">tesseract-3.0x\training\Makefile.am</span> and look at the
<tt class="docutils literal"><span class="pre">bin_PROGRAMS</span></tt> variable to see the list), the easiest thing to do
is copy another existing training application Project and manually
change it.</p>
<p>For example, assuming the new training application is
called <span class="filesystem">new_trainer.exe</span>, with the Solution closed:</p>
<ol class="loweralpha">
<li><p class="first">Copy the <span class="filesystem">ambiguous_words</span> directory to a new directory called

<li><p class="first">Change the <span class="filesystem">new_trainer\ambiguous_words.vcproj</span> filename to
<span class="filesystem">new_trainer\new_trainer.vcproj</span>.</p>
</li>
<li><p class="first">Edit <span class="filesystem">new_trainer\new_trainer.rc</span> and change all occurrences of
<tt class="docutils literal"><span class="pre">ambiguous_words</span></tt> to <tt class="docutils literal"><span class="pre">new_trainer</span></tt>.</p>
<p>Also change <tt class="docutils literal"><span class="pre">FileDescription</span></tt> to describe the new application.</p>
</li>
<li><p class="first">Open up the <strong>Tesseract-OCR</strong> Solution file and right-click the
<em class="guilabel">Solution:&#8217;tesseract&#8217;</em> in the Solution Explorer. Choose
<em class="menuselection">A<span class="accelerator">d</span>d ‣ <span class="accelerator">E</span>xisting Project...</em> from the context
menu and add the <span class="filesystem">new_trainer\new_trainer.vcproj</span> you just

</li>
<li><p class="first">Right-click the newly added Project, and choose
<em class="menuselection">Project Dependencie<span class="accelerator">s</span>...</em>.</p>
<p>The <em class="guilabel">Project Dependencies</em> Dialog will open. Make sure
that <span class="filesystem">libtesseract30x</span> is checked. If you forget this step, Visual
Studio will not automatically link with <span class="filesystem">libtesseract</span> and
you&#8217;ll get lots of &#8220;unresolved external symbol&#8221; errors.</p>
</li>
</ol>
<p>This actually goes pretty fast. It should only take you a minute or
so to add a new application to the <strong>Tesseract-OCR</strong> Solution.</p>
</li>
<li><p class="first">(Optional?) Edit <span class="filesystem">vs2008\Sphinx\versions.rst</span> and add a new entry
describing the changes made for this new version.</p>
</li>
<li><p class="first">To make your working directory suitable for reposting back to the
<strong>Tesseract-OCR</strong> SVN repository, you need to ignore all the following:</p>
<ul>
<li><p class="first">All <span class="filesystem">LIB_Release</span>, <span class="filesystem">LIB_Debug</span>, <span class="filesystem">DLL_Release</span>, <span class="filesystem">DLL_Debug</span>

<li><p class="first">All <span class="filesystem">.user</span> files</p>

</li>
<li><p class="first"><span class="filesystem">vs2008\newsources.txt</span></p>
</li>
</ul>
<p>Optionally, the <span class="filesystem">tesshelper.py</span> script has the <tt class="docutils literal"><span class="pre">clean</span></tt> command
which will remove the above items. To run it, open a Command Prompt
window and then do:</p>
<div class="highlight-none"><div class="highlight"><pre>cd &lt;tesseract-3.0x install dir&gt;\vs2008
python tesshelper .. clean
</pre></div>
</div>
<p>The script will respond with the following:</p>
<div class="highlight-none"><div class="highlight"><pre>Are you sure you want to clean the
&quot;C:\BuildFolder\tesseract-3.0x\vs2008&quot; folder (Yes/No) [No]? yes
Only list the items to be deleted (Yes/No) [Yes]? no
</pre></div>
</div>
<p>You have to answer <tt class="docutils literal"><span class="pre">yes</span></tt> and then <tt class="docutils literal"><span class="pre">no</span></tt> to the prompts. Otherwise
either the script will just exit, or only list the items that will be
removed instead of actually removing them (which is a good thing to
try first just in case).</p>

<h1>Overview<a class="headerlink" href="#overview" title="Permalink to this headline"></a></h1>
<p>The recommended audience for this document are developers who want to
use Microsoft Visual Studio 2008 with <a class="reference external" href="http://code.google.com/p/tesseract-ocr/">Tesseract-OCR</a>. If you simply want to <em>run</em>
<span class="filesystem">tesseract</span> or its various language training applications, then see the
<a class="reference external" href="http://code.google.com/p/tesseract-ocr/wiki/ReadMe">ReadMe</a>. You&#8217;ll
find instructions there on how to download tesseract&#8217;s Windows
installer.</p>
<p><strong>Tesseract-OCR</strong> consists of:</p>
<ul>
<li><p class="first"><span class="filesystem">libtesseract</span> &#8211; the static (or dynamic) library that does all the
actual work. As of February 2012 it consists of 260+ <span class="filesystem">C++</span> files
along with 290+ header files.</p>
</li>
<li><p class="first"><span class="filesystem">tesseract.exe</span> &#8211; the command-line OCR engine. It&#8217;s built from a
single, small <span class="filesystem">C++</span> file that just calls functions in
<span class="filesystem">libtesseract</span>. There currently isn&#8217;t very much documentation on how
to use <span class="filesystem">tesseract.exe</span>, but you can look at what&#8217;s there in the
repository&#8217;s <a class="reference external" href="http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc">doc</a>
subdirectory.</p>

</li>
<li><p class="first"><span class="filesystem">combine_tessdata.exe</span> &#8211; combine/extract/overwrite Tesseract data</p>

<h1>Programming with <span class="filesystem">libtesseract</span><a class="headerlink" href="#programming-with-libtesseract" title="Permalink to this headline"></a></h1>
<p>To use <span class="filesystem">libtesseract</span> in your own application you need to include
<strong>Leptonica</strong>’s <span class="filesystem">allheaders.h</span>, and <strong>Tesseract-OCR</strong>’s <span class="filesystem">baseapi.h</span> and
<span class="filesystem">strngs.h</span>.</p>
<p><strong>Tesseract-OCR</strong> uses <span class="filesystem">liblept</span> mainly for image I/O, but you can also use
any of <strong>Leptonica</strong>’s <em>many</em> image processing functions on <tt class="docutils literal"><span class="pre">PIX</span></tt>,
while at the same time calling <tt class="docutils literal"><span class="pre">TessBaseAPI</span></tt> methods. See the
<a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/">Leptonica documentation</a>
for more details.</p>
<p>There doesn&#8217;t seem to be any documentation on <span class="filesystem">api\baseapi.h</span>, but it
has extensive comments. You can also look at the <a class="reference internal" href="#apitest"><em>APITest Sample</em></a> and
<a class="reference internal" href="#apiexamples"><em>APIExamples</em></a> projects.</p>
<p>See the <a class="reference internal" href="#apitest"><em>APITest Sample</em></a> project for an example of which compiler and
linker settings you need for various build configurations. The easiest
way to begin a new application is to just make a copy of the <span class="filesystem">APITest</span>
directory. See <a class="reference internal" href="maintenance.html#copying-a-project"><em>this step</em></a> for detailed
instructions (skip the last step about adding <em class="guilabel">Project
Dependencies</em>).</p>
<p>If you want to manually set the required settings, then here&#8217;s the list
of things to do:</p>
<ol class="arabic">
<li><p class="first">Add the following <em class="guilabel">Preprocessor Definitions</em> when compiling
any files that include <span class="filesystem">baseapi.h</span> and you are linking with the
static library versions of <span class="filesystem">libtesseract</span>:</p>
<div class="highlight-none"><div class="highlight"><pre>USE_STD_NAMESPACE
</pre></div>
</div>
<p>If you are linking with the DLL versions of <span class="filesystem">libtesseract</span> instead
add:</p>
<div class="highlight-none"><div class="highlight"><pre>USE_STD_NAMESPACE;TESSDLL_IMPORTS;CCUTIL_IMPORTS;LIBLEPT_IMPORTS
</pre></div>
</div>
</li>
<li><p class="first">Be sure to add the following to <em class="guilabel">Additional Include
Directories</em>:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\include
C:\BuildFolder\include\leptonica
C:\BuildFolder\include\tesseract or
&lt;tesseract-3.0x dir&gt; (all its sub-directories that contain header files)
</pre></div>
</div>
</li>
<li><p class="first">Add <span class="filesystem">C:\BuildFolder\lib</span> to your <em class="guilabel">Additional Library
Directories</em>.</p>
</li>
<li><p class="first">In the <span class="filesystem">C:\BuildFolder\include</span> directory are two Visual Studio
Property Sheet files:</p>
<div class="highlight-none"><div class="highlight"><pre>tesseract_versionnumbers.vsprops
leptonica_versionnumbers.vsprops
</pre></div>
</div>
<p>Using <span class="filesystem">tesseract_versionnumbers.vsprops</span> (which automatically inherits
<span class="filesystem">leptonica_versionnumbers.vsprops</span>) can make it easier to specify the
libraries you need to import. For example, when creating a staticly
linked debug executable you can say:</p>
<div class="highlight-none"><div class="highlight"><pre>zlib$(ZLIB_VERSION)-static-mtdll-debug.lib
libpng$(LIBPNG_VERSION)-static-mtdll-debug.lib
libjpeg$(LIBJPEG_VERSION)-static-mtdll-debug.lib
giflib$(GIFLIB_VERSION)-static-mtdll-debug.lib
libtiff$(LIBTIFF_VERSION)-static-mtdll-debug.lib
liblept$(LIBLEPT_VERSION)-static-mtdll-debug.lib
libtesseract$(LIBTESS_VERSION)-static-debug.lib
</pre></div>
</div>
<p>to make your application less dependent on library version numbers.</p>
<p>To add the Property Sheet to a Project, open its <em class="guilabel">Properties
Pages</em> Dialog, and set the <em class="guilabel">Configuration Properties |
General | Inherited Project Property Sheets</em> item to:</p>
<div class="highlight-none"><div class="highlight"><pre>..\..\..\include\tesseract_versionnumbers.vsprops
</pre></div>
</div>
<p>Choosing <em class="menuselection"><span class="accelerator">V</span>iew ‣ Oth<span class="accelerator">e</span>r Windows ‣ Property
<span class="accelerator">M</span>anager</em> from the menubar will let you see the Properties attached
to each Project&#8217;s configurations.</p>
</li>
</ol>
<div class="admonition note">

are those classes. However, if you find yourself having to manipulate
other &#8220;internal&#8221; tesseract objects then you currently have to link

<div class="section" id="debugging-tips">
<h2>Debugging Tips<a class="headerlink" href="#debugging-tips" title="Permalink to this headline"></a></h2>
<p>Before debugging programs written with <span class="filesystem">libtesseract</span>, you should first
download the latest Leptonica sources (currently
<span class="filesystem">leptonica-1.68.tar.gz</span>) and VS2008 source package (<span class="filesystem">vs2008-1.68.zip</span>)
from:</p>
<ul>
<li><p class="first"><a class="reference external" href="http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68.tar.gz">http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68.tar.gz</a></p>

</li>
</ul>
<p>Unpack them to <span class="filesystem">C:\BuildFolder</span> to get the following directory structure:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\

<p>(see <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-liblept.html">Building the liblept library</a>
for more information)</p>
<p><strong>Tesseract-OCR</strong> uses <strong>Leptonica</strong> &#8220;under the hood&#8221; for all (most? some?)
of its image processing operations. Having the source available (and
compiling it in debug mode) will make it easier to see what&#8217;s really
going on.</p>
<p>You might want to add
<span class="filesystem">C:\BuildFolder\leptonica-1.68\vs2008\leptonica.vcproj</span> and
<span class="filesystem">C:\BuildFolder\tesseract-3.02\vs2008\libtesseract\libtesseract.vcproj</span>
to your solution by right-clicking it and choosing <em class="menuselection">A<span class="accelerator">d</span>d ‣
<span class="accelerator">E</span>xisting Project...</em>. This seems to make VS2008&#8217;s Intellisense <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-other-programs.html#intellisense-and-liblept">work
better</a>
when finding &#8220;external&#8221; source files.</p>
<p>Definitely create a <tt class="docutils literal"><span class="pre">TESSDATA_PREFIX``x</span> <span class="pre">environment</span> <span class="pre">variable</span> <span class="pre">so</span> <span class="pre">that</span> <span class="pre">it</span>

<span class="pre">``tessdata</span></tt> directory. Otherwise you&#8217;ll have to put a <tt class="docutils literal"><span class="pre">tessdata</span></tt>
directory in every temporary build folder which quickly becomes painful
(especially since tessdata has gotten very big &#8212; 600MB!).</p>

<p>The <em class="guilabel">APITest</em> contains just the <em class="guilabel">baseapitester</em>
project. This was created using the VS2008 <em class="guilabel">Win32 Console
Application</em> Project Wizard and then just copying most of
<span class="filesystem">tesseractmain.cpp</span> and making minor edits. Its settings correctly refer
to the &#8220;public&#8221; <span class="filesystem">include</span> and <span class="filesystem">lib</span> directories using relative paths.</p>
<p>It assumes that the <span class="filesystem">C:\BuildFolder\include</span> directory has been
properly setup. See <a class="reference internal" href="setup.html#copying-headers"><em>this</em></a> for more details.</p>
<p>The <span class="filesystem">C:\BuildFolder\lib</span> directory will automatically get
<span class="filesystem">libtesseract</span> copied to it whenever it is built.</p>
<p>The <span class="filesystem">include\tesseract_versionnumbers.vsprops</span> Property Sheet is used
to avoid explicit library version number dependencies. Precompiled
headers are used. <em class="guilabel">LIB_Release</em>, <em class="guilabel">LIB_Debug</em>,
<em class="guilabel">DLL_Release</em>, and <em class="guilabel">DLL_Debug</em> build configurations
are supported.</p>
<p>The following are the compiler command lines and linker options
used. See <a class="reference external" href="http://msdn.microsoft.com/en-us/library/9s7c9wdw(v=vs.90).aspx">Compiling a C/C++ Program | Compiler Options</a> for a

<h1>Setting up <strong>Tesseract-OCR</strong><a class="headerlink" href="#setting-up-tesseractocr" title="Permalink to this headline"></a></h1>
<p>The Visual Studio 2008 Solutions included with <strong>Tesseract-OCR</strong>, rely on
<em>relative paths</em> to reference files and directories &#8212; including
locations that are <em>outside</em> of the <span class="filesystem">tesseract-3.0x</span> tree. It is
therefore vitally important to correctly set up the directories for the
various components. This section describes how to do this.</p>
<div class="section" id="initial-build-directory-setup">
<span id="directory-setup"></span><h2>Initial &#8220;Build&#8221; directory setup<a class="headerlink" href="#initial-build-directory-setup" title="Permalink to this headline"></a></h2>
<p>First create an empty directory where you will unpack all the required
downloads. Assume you call this directory <span class="filesystem">C:\BuildFolder</span>.</p>
<ol class="arabic" id="download-leptonica">
<li><p class="first">Download the <strong>Leptonica</strong> 1.68 pre-built binary package
(<span class="filesystem">leptonica-1.68-win32-lib-include-dirs.zip</span>) from:</p>
<blockquote>
<div><p><a class="reference external" href="http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68-win32-lib-include-dirs.zip">http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68-win32-lib-include-dirs.zip</a></p>
</div></blockquote>
<p>and unpack it to <span class="filesystem">C:\BuildFolder</span>.</p>
</li>
<li><p class="first"><strong>Leptonica</strong>, even on Windows as of v1.68, still requires a few unix
utilities (like <span class="filesystem">rm</span>, <span class="filesystem">diff</span>, <span class="filesystem">sleep</span>). The easiest way to deal with
this is to follow the instructions at <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html">Installing Cygwin coreutils</a>.</p>
</li>
</ol>
<p>At this point, if all you want to do is link with <span class="filesystem">libtesseract</span> you can
<a class="reference external" href="http://code.google.com/p/tesseract-ocr/downloads/list">download</a> the
file that just contains the &#8220;public&#8221; <strong>Tesseract-OCR</strong> headers along with
the precompiled library binaries for Windows. Unpack it to
<span class="filesystem">C:\BuildFolder</span> and you&#8217;ll now have:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\
include\
leptonica\

libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
</pre></div>
</div>
<p>and you can skip the rest of this page and go directly to
<a class="reference internal" href="programming.html"><em>Programming with libtesseract</em></a>.</p>
<p>The recommended action, however, is to download the <strong>Tesseract-OCR</strong>
sources and build them yourself. Therefore...</p>
<ol class="arabic" start="3">
<li><p class="first">Download the <strong>Tesseract-OCR</strong> Visual Studio 2008 source files from the
<a class="reference external" href="http://code.google.com/p/tesseract-ocr/downloads/list">downloads page</a>. If, for
example, you&#8217;d like to build v3.02 you would use the following link:</p>
<blockquote>
<div><p><a class="reference external" href="http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-3.02-vs2008.zip">http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-3.02-vs2008.zip</a></p>
</div></blockquote>
<p>Unpack the file to <span class="filesystem">C:\BuildFolder</span></p>
</li>
</ol>
<p>You would now have the following directory structure:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\

<ol class="arabic" start="4">
<li><p class="first">Download the <strong>Tesseract-OCR</strong> source files for the same version as the

</div></blockquote>
<p>Unpack the file to <span class="filesystem">C:\BuildFolder</span></p>
</li>
</ol>
<p>This will add a bunch of directories to your already existing

<p>If you&#8217;d like to try the absolute latest version of <strong>Tesseract-OCR</strong>,
here&#8217;s how to download the source files from its SVN repository:</p>
<ol class="arabic">
<li><p class="first">Follow Steps 1 and 2 <a class="reference internal" href="#directory-setup"><em>above</em></a>.</p>

the <strong>Tesseract-OCR</strong> sources to a directory on your computer. This
directory should <em class="bold-italic">not</em> be <span class="filesystem">C:\BuildFolder</span>!</p>
<p>If you are unfamiliar with <a class="reference external" href="http://subversion.apache.org/">SVN</a>,
the easiest way to do this is to first download and install
<a class="reference external" href="http://tortoisesvn.net/">TortoiseSVN</a> and then:</p>
<ol class="loweralpha">
<li><p class="first">Right-click the (empty) directory where you want the working copy

</li>
<li><p class="first">Enter <tt class="docutils literal"><span class="pre">http://tesseract-ocr.googlecode.com/svn/trunk/</span></tt> for
<em class="guilabel"><span class="accelerator">U</span>RL of repository</em>. You can keep all the other
settings at their defaults.</p>
<img alt="TortoiseSVN Checkout Dialog Box" class="align-center" src="_images/tortoisesvn_checkout.png" />
</li>
<li><p class="first">Click the <em class="guilabel"><span class="accelerator">O</span>K</em> button to commence downloading the
<strong>Tesseract-OCR</strong> sources to your computer. This might take a while as
the language data in the <span class="filesystem">tessdata</span> directory is quite large. As
of February 2012, about 335MB needs to be transferred for the
initial checkout. The total size of the resulting working copy is
about 1.2GB.</p>
</li>
<li><p class="first">Keeping your working copy up to date after this is as simple as
right-clicking its directory and choosing <em class="menuselection">SVN
<span class="accelerator">U</span>pdate</em>. Unlike the initial checkout, this will usually finish
very quickly.</p>
</li>
</ol>
</li>
<li><p class="first">Copy the <em class="bold-italic">contents</em> of your working directory, except for the
<span class="filesystem">tessdata</span> directory, to <span class="filesystem">C:\BuildFolder\tesseract-3.0x</span>, where

<tt class="docutils literal"><span class="pre">beta</span></tt>, etc.</p>
</li>
<li><p class="first">Optionally, follow Step 5 from <a class="reference internal" href="#copying-headers"><em>above</em></a>.</p>
</li>
<li><p class="first">You&#8217;ll probably want to set an environment varible named

<h2><a class="reference external" href="http://tortoisesvn.net/">TortoiseSVN</a><a class="headerlink" href="#id1" title="Permalink to this headline"></a></h2>
<p>The <strong>Tesseract-OCR</strong> source lives in an SVN repository at <a class="reference external" href="http://code.google.com/p/tesseract-ocr/source/checkout">Google Code</a>, so to
<a class="reference internal" href="setup.html#using-latest-sources"><em>build the latest versions</em></a> you&#8217;ll need to
know SVN. For newcomers (or not), TortoiseSVN (<a class="reference external" href="http://tortoisesvn.net/">http://tortoisesvn.net/</a>)
is a great alternative to the SVN command line interface.</p>
<p>&#8220;TortoiseSVN is an easy-to-use SCM / source control software for
Microsoft Windows and possibly the best standalone Apache Subversion
client there is. It is implemented as a Windows shell extension, which
makes it integrate seamlessly into the Windows explorer. Since it&#8217;s not
an integration for a specific IDE you can use it with whatever
development tools you like.&#8221;</p>

<div class="section" id="id2">
<h2><a class="reference external" href="http://jpsoft.com/tccle_cmd_replacement.html">JP Software TCC/LE</a><a class="headerlink" href="#id2" title="Permalink to this headline"></a></h2>
<p>Instead of using Windows&#8217; plain old Command Prompt window &#8212; and less
intimidating than using the bash shell from <a class="reference external" href="http://cygwin.com/">cygwin</a> or <a class="reference external" href="http://mingw.org/wiki/msys">MSYS</a> &#8212; the
&#8220;TCC/LE - Windows CMD Replacement Command Console&#8221; by JP Software is
definitely worth trying. It is available at
<a class="reference external" href="http://jpsoft.com/tccle_cmd_replacement.html">http://jpsoft.com/tccle_cmd_replacement.html</a>.</p>
<p>For example, to look for all the settable options in <strong>Tesseract-OCR</strong>,
try:</p>
<div class="highlight-none"><div class="highlight"><pre>C:\BuildFolder\tesseract-3.02\
ffind /s/v/c/t&quot;_MEMBER&quot; *.cpp | list/s
</pre></div>
</div>
<p>and you&#8217;ll get something that looks like this in the <span class="filesystem">list</span> viewer:</p>
<div class="highlight-none"><div class="highlight"><pre>---- C:\BuildFolder\tesseract-3.02\ccmain\tesseractclass.cpp
: BOOL_MEMBER(tessedit_resegment_from_boxes, false,
BOOL_MEMBER(tessedit_resegment_from_line_boxes, false,
BOOL_MEMBER(tessedit_train_from_boxes, false,
BOOL_MEMBER(tessedit_make_boxes_from_boxes, false,
BOOL_MEMBER(tessedit_dump_pageseg_images, false,
...
double_MEMBER(segsearch_max_char_wh_ratio, 2.0,
double_MEMBER(segsearch_max_fixed_pitch_char_wh_ratio, 2.0,
BOOL_MEMBER(save_alt_choices, false,
413 lines in 7 files
</pre></div>
</div>
<p>(Press the <tt class="kbd docutils literal"><span class="pre">Escape</span></tt> key to exit the <span class="filesystem">list</span> viewer).</p>
<p>The equivalent(?) Linux incantation, copied and slightly modified from
the grep info, is:</p>
<div class="highlight-none"><div class="highlight"><pre>find . -name &#39;*.cpp&#39; -print0 | xargs -0r grep -H &#39;_MEMBER&#39; | less
</pre></div>
</div>
<p>Note: You can also do this directly in Visual Studio 2008, by choosing
<em class="menuselection"><span class="accelerator">E</span>dit ‣ <span class="accelerator">F</span>ind and Replace ‣ F<span class="accelerator">i</span>nd in Files</em>
(<tt class="kbd docutils literal"><span class="pre">Ctrl+Shift+F</span></tt>), so maybe this wasn&#8217;t the best example:</p>

<p>&#8220;<a class="reference external" href="http://cygwin.com/">Cygwin</a> is a collection of tools which provide a
Linux look and feel environment for Windows.&#8221;</p>
<p><strong>Leptonica</strong> actually still requires a few unix utilities (like <span class="filesystem">rm</span>,
<span class="filesystem">diff</span>, <span class="filesystem">sleep</span>) for some operations and might silently fail if it they
not present (as of v1.68). The easiest way to deal with this is to
<a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html">install Cygwin</a>
or MSYS (see the next section).</p>

<p>&#8220;<a class="reference external" href="http://mingw.org/wiki/msys">MSYS</a> is a collection of GNU utilities
such as bash, make, gawk and grep to allow building of applications and

<div class="section" id="windiff">
<h2>WinDiff<a class="headerlink" href="#windiff" title="Permalink to this headline"></a></h2>
<p>An important phase of testing <span class="filesystem">tesseract</span> is checking how its output
compares to previous runs (or ground-truth files). A visual diff program
can make that easier.</p>
<p>Microsoft&#8217;s WinDiff doesn&#8217;t seem to come with Visual Studio
anymore. However it can still be downloaded from <a class="reference external" href="http://www.grigsoft.com/download-windiff.htm">Grig Software</a> (without having to get
all the other stuff in the <a class="reference external" href="http://www.microsoft.com/download/en/details.aspx?displaylang=en&amp;id=18546">Windows XP Service Pack 2 Support Tools</a>.</p>
<p>Other options are <a class="reference external" href="http://kdiff3.sourceforge.net/">KDiff3</a> and
<a class="reference external" href="http://www.prestosoft.com/edp_examdiff.asp">ExamDiff</a> (<a class="reference external" href="http://www.prestosoft.com/edp_examdiffpro.asp">ExamDiff Pro</a> is also recommended
but it&#8217;s not free).</p>
<p>KDiff3 doesn&#8217;t seem to correctly auto-detect UTF-8 encodings so choose
<em class="menuselection"><span class="accelerator">S</span>ettings ‣ <span class="accelerator">C</span>onfigure KDiff3...</em> from the menubar and
set the <em class="guilabel">Regional Settings</em> tab as follows:</p>
<img alt="KDiff3 Regional Settings" class="align-center" src="_images/kdif3_settings.png" />
<p>Also on the <em class="guilabel">Integration</em> tab, make sure that <em class="guilabel">Quit
also via Escape key</em> is turned on (checked). Since IrfanView also quits
when you press the <tt class="kbd docutils literal"><span class="pre">Esc</span></tt> key, this just makes it easy to dismiss
both applications with the same key.</p>
<p>Here is KDiff3 showing the (slight) difference in OCR results after
deskewing a grayscale image:</p>

<h2><a class="reference external" href="http://dependencywalker.com/">Dependency Walker</a><a class="headerlink" href="#id11" title="Permalink to this headline"></a></h2>
<p>If you&#8217;re having problems with missing module runtime errors, the
Dependency Walker (<a class="reference external" href="http://dependencywalker.com/">http://dependencywalker.com/</a>) usually can help track
down the problem.</p>
<p>&#8220;Dependency Walker is also very useful for troubleshooting system errors
related to loading and executing modules. Dependency Walker detects many
common application problems such as missing modules, invalid modules,
import/export mismatches, circular dependency errors, mismatched machine
types of modules, and module initialization failures.&#8221;</p>
<p>You probably want the 32-bit version even if you are running on a
Windows 64-bit platform, because the current VS2008 Solution for
<strong>Tesseract-OCR</strong> by default builds a 32-bit app. From the <a class="reference external" href="http://dependencywalker.com/faq.html">FAQ</a></p>
<blockquote>
<div>&#8220;There are 32-bit and 64-bit versions Dependency Walker. All versions
are capable or opening 32-bit and 64-bit modules. However, there are
major advantages to using the 32-bit Dependency Walker to process 32-bit
modules and the 64-bit Dependency Walker to process 64-bit modules.
This is especially true when running on a 64-bit version of Windows,
which allows execution of both 32-bit and 64-bit programs. The 32-bit
subsystem on 64-bit Windows (known as &#8220;WOW64&#8221;) has its own private
registry, &#8220;AppPaths&#8221;, &#8220;KnownDlls&#8221;, system folders, and manifest
processing. Only the 32-bit version of Dependency Walker can access
this 32-bit environment, which is needed to accurately process a 32-bit
module. Likewise, only the 64-bit version of Dependency Walker can
fully access the 64-bit environment, so it should always be used for
processing 64-bit modules.&#8221;</div></blockquote>

</div>
<p>The above image shows Dependency Walker used on
<span class="filesystem">tesseract-dlld.exe</span>. The panes show the <span class="filesystem">DLL</span>s that it is dependent
on, the methods it actually uses from <span class="filesystem">libtesseract302d.dll</span>, and all
the exported methods from <span class="filesystem">libtesseract302d.dll</span>. Using this it&#8217;s easy
to see that only the <tt class="docutils literal"><span class="pre">TessBaseAPI</span></tt> and <tt class="docutils literal"><span class="pre">STRING</span></tt> classes are exported
as mentioned in <a class="reference internal" href="programming.html"><em>Programming with libtesseract</em></a>.</p>

<p>Another essential program to help figure out what your program is doing
is Process Explorer
(<a class="reference external" href="http://technet.microsoft.com/en-us/sysinternals/bb896653">http://technet.microsoft.com/en-us/sysinternals/bb896653</a>).</p>
<p>&#8220;The unique capabilities of Process Explorer make it useful for tracking
down DLL-version problems or handle leaks, and provide insight into the
way Windows and applications work.&#8221;</p>

<h2><a class="reference external" href="http://www.vmware.com/products/player/">VMware Player</a><a class="headerlink" href="#id13" title="Permalink to this headline"></a></h2>
<p>VMware Player (<a class="reference external" href="http://www.vmware.com/products/player/">http://www.vmware.com/products/player/</a>) can be used to
install, for example, <a class="reference external" href="http://www.ubuntu.com/">Ubuntu 11.10</a> in a
virtual machine on Windows and see how the other half lives. It also
helps when trying to figure out if the Windows version of <span class="filesystem">tesseract</span>
acts the same way as the &#8220;original&#8221; version.</p>
<p>&#8220;VMware Player is the easiest way to run multiple operating systems at
the same time on your PC. With its user-friendly interface, VMware
Player makes it effortless for anyone to try out Windows 8 developer
release, Windows 7, Chrome OS or the latest Linux releases, or create
isolated virtual machines to safely test new software and surf the Web.&#8221;</p>

version number &#8220;user macros&#8221;, in all Visual Studio Projects. These are
also copied to <span class="filesystem">C:\BuildFolder\include</span>, so you can refer to them in
your own projects. By using the new <tt class="docutils literal"><span class="pre">*_VERSION</span></tt> macros, you&#8217;ll be
isolated from worrying about version number changes in the library
filenames.</p>
<p>See <a class="reference internal" href="programming.html#apitest"><em>APITest&#8217;s</em></a> <a class="reference internal" href="programming.html#apitest-lib-release"><em>LIB_Release</em></a> Linker
<em class="guilabel">Additional Dependencies</em> settings for an example of what
this looks like in practice.</p>
<p>See <strong>Leptonica</strong>’s explanation <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers">About version numbers in library
filenames</a>
for more details.</p>
</li>
<li><p class="first">Added a <a class="reference internal" href="building.html#version-resource"><em>Version Resource</em></a> to all DLLs and
applications.</p>
</li>
<li><p class="first">Removed inclusion of the <strong>Leptonica</strong> libraries. They now have to be
<a class="reference internal" href="setup.html#download-leptonica"><em>downloaded separately</em></a>.</p>
</li>
<li><p class="first">Changed to a <a class="reference internal" href="setup.html#directory-setup"><em>Build directory structure</em></a> that
is compatible with <strong>Leptonica</strong> and allows the building of
<strong>Tesseract-OCR</strong>-based applications using only the <span class="filesystem">include</span> and <span class="filesystem">lib</span>
directories.</p>
</li>
<li><p class="first">The <span class="filesystem">libtesseract</span> libraries are now named as follows:</p>
<p>static libraries:</p>
<ul>
<li><p class="first">libtesseract302-static.lib</p>
</li>
<li><p class="first">libtesseract302-static-debug.lib</p>

</li>
<li><p class="first">libtesseract302d.dll</p>
</li>
</ul>
</li>
<li><p class="first">Used compiler and linker settings based on the <strong>Leptonica</strong> <a class="reference external" href="http://tpgit.github.com/UnOfficialLeptDocs/vs2008/index.html">VS2008
Developer package</a>.</p>
</li>
<li><p class="first">Removed all preprocessor defines of <tt class="docutils literal"><span class="pre">__MSW32__</span></tt> which is no longer
needed.</p>
</li>
<li><p class="first">Removed <span class="filesystem">vs2008includestdint.h</span> which is no longer required to build
<span class="filesystem">liblept</span>.</p>
</li>
<li><p class="first">Removed <span class="filesystem">vs2008includeinttypes.h</span> which isn&#8217;t needed to build
<span class="filesystem">liblept</span>.</p>
</li>
<li><p class="first">Turned off the following compiler warnings:</p>
<div class="highlight-none"><div class="highlight"><pre>/wd4005: &#39;snprintf&#39; : macro redefinition
/wd4018 &#39;expression&#39; : signed/unsigned mismatch

/wd4996 &#39;function&#39;: was declared deprecated
</pre></div>
</div>
</li>
<li><p class="first">Used the &#8220;C7 Compatible&#8221; Debug Information (/Z7) compiler switch,
which puts the debugging information in the .obj files. That way we
don&#8217;t have to worry about also supplying <span class="filesystem">.pdb</span> files. See <a class="reference external" href="http://msdn.microsoft.com/en-us/library/958x11bc(VS.90).aspx">/Z7,
/Zi, /ZI (Debug Information Format)</a> for
more information.</p>
</li>
<li><p class="first">Added Projects for the following new <a class="reference internal" href="overview.html#training-applications"><em>training applications</em></a>:</p>
<ul>
<li><p class="first">ambiguous_words</p>
</li>
<li><p class="first">classifier_tester</p>

<li><p class="first">dawg2wordlist</p>
</li>
<li><p class="first">shapeclustering</p>
</li>
</ul>
</li>
<li><p class="first">Moved <span class="filesystem">mathfix.h</span> from <span class="filesystem">vs2008\include</span> to the <span class="filesystem">vs2008\port</span>
directory.</p>
</li>
<li><p class="first">Removed Visual Studio 2010 support. See <a class="reference internal" href="vs2010-notes.html"><em>Using Visual Studio 2010</em></a> for the
rationale.</p>
</li>
<li><p class="first">Created a python script called <a class="reference internal" href="maintenance.html#tesshelper"><em>tesshelper.py</em></a>, that
eases some maintenance tasks related to releasing future VS2008
Solutions.</p>
</li>
<li><p class="first">The list of &#8220;public&#8221; header files that are required to build
&#8220;external&#8221; applications is now limited to the following 13 files:</p>

=========================
Building |Tesseractocr|
=========================
The Visual Studio 2008 Solution for |Tesseractocr| builds:
+ `libtesseract`
+ `tesseract.exe`
+ 9 training applications (for v3.02)
Unlike earlier Solutions only a single `libtesseract` library is
generated --- the twelve projects matching the twelve source subfolders
have been abandoned. They were deemed too complicated since they were
never (rarely?) used by themselves, but only along with the entire
library.
In addition, `libtesseract` and `tesseract.exe` can be built using four
configurations: :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug`.
Two Visual Studio Property Sheets, `leptonica_versionnumbers.vsprops`
and `tesseract_versionnumbers.vsprops`, are employed to isolate the
Solution from changes in dependency version numbers (and isolate
dependent Solutions). See :ref:`APITest's <APITest>` :ref:`LIB_Release
<apitest-lib-release>` Linker :guilabel:`Additional Dependencies`
settings for an example of what this looks like in practice. See
|Leptonica|\ ’s explanation `About version numbers in library filenames
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers>`_
for the rationale behind using Property Sheets.
Building `libtesseract` and `tesseract.exe`
===========================================
1. Open `C:\\BuildFolder\\tesseract-3.0x\\vs2008\\tesseract.sln` in Visual
Studio 2008.
You'll see the following projects in the :guilabel:`Solution
Explorer` (for v3.02)::
ambiguous_words
classifier_tester
cntraining
combine_tessdata
dawg2wordlist
libtesseract302
mftraining
shapeclustering
tesseract
unicharset_extractor
wordlist2dawg
2. Select the build configuration you'd like to use from the
:guilabel:`Solution Configurations` dropdown. It lists the following
configurations::
DLL_Debug
DLL_Release
LIB_Debug
LIB_Release
The `DLL_` configurations build the DLL version of `libtesseract-3.0x`
(and link with the DLL version of Leptonica 1.68). The `LIB_`
configurations build the static library version of `libtesseract-3.0x`
(and link with the static version of Leptonica 1.68 and the required
image libraries).
3. Build `libtesseract` by right-clicking the
:guilabel:`libtesseract30x` project and choosing
:menuselection:`B&uild` from the pop-up menu.
The resultant library will be written to the
`C:\\BuildFolder\\tesseract-3.0x\\vs2008\\<ConfigurationName>` directory
where `<ConfigurationName>` is the same as the build configuration you
selected earlier. It is also copied to the `C:\\BuildFolder\\lib` folder
to make it easy to link your own applications to `libtesseract`.
The library is named as follows (for v3.02):
.. parsed-literal::
static libraries:
`libtesseract302-static.lib`
`libtesseract302-static-debug.lib`
DLLs:
`libtesseract302.lib` (import library)
`libtesseract302.dll`
`libtesseract302d.lib` (import library)
`libtesseract302d.dll`
4. Build the main tesseract OCR application by right-clicking the
:guilabel:`tesseract` project and choosing :menuselection:`B&uild`.
The resultant executable will be written to the
`C:\\BuildFolder\\tesseract-3.0x\\vs2008\\<ConfigurationName>` directory
where `<ConfigurationName>` is the same as the build configuration you
selected earlier. It is named as follows:
.. parsed-literal::
LIB_Release: `tesseract.exe`
LIB_Debug: `tesseractd.exe`
DLL_Release: `tesseract-dll.exe`
DLL_Debug: `tesseract-dlld.exe`
Testing `tesseract.exe`
=======================
It's usually better to make a separate directory to test
`tesseract.exe`. To run tesseract, you either need to make sure your
test directory contains the `tessdata` tesseract language data folder or
you set the ``TESSDATA_PREFIX`` environment variable to point to it. See
http://code.google.com/p/tesseract-ocr/wiki/ReadMe for important
details.
For example, you can use the following directory structure::
C:\BuildFolder\
include\
lib\
tesseract-3.02\
testing\
tessdata\
Copy your tesseract executable to `C:\\BuildFolder\\testing`. If you
built a DLL version then be sure to also copy the required DLLs to the
same directory (or add `C:\\BuildFolder\\lib` to your ``PATH`` --
However, this isn't really recommended).
For example, if you are trying to run `tesseractd.exe` then you'll need
to also copy the following to `C:\\BuildFolder\\testing`::
liblept168d.dll
libtesseract302d.dll
Copy a few test images to `C:\\BuildFolder\\testing` just to make it easy
to run test commands.
Test tesseract by doing something like the following::
tesseractd.exe eurotext.tif eurotext
This will create a file called `eurotext.txt` that will contain the
result of OCRing `eurotext.tif`.
Building the training applications
==================================
The training related applications are built using the following
projects::
ambiguous_words
classifier_tester
cntraining
combine_tessdata
dawg2wordlist
mftraining
shapeclustering
unicharset_extractor
wordlist2dawg
.. note::
Currently these applications can **ONLY** be built with the LIB_Debug
and LIB_Release configurations. If you try to use a DLL configuration
you'll get "undefined external symbol" errors.
To build one of the above training applications, simply right-click one
of the projects in the Solution Explorer, and choose
:menuselection:`B&uild` from the pop-up menu.
Alternatively, you can build :bi:`everything` in the Solution by
choosing :menuselection:`&Build --> &Build Solution` (:kbd:`Ctrl+Shift+B`)
from the menu bar.
See http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3 for
more information on using these applications.
.. _building-with-vc2008-express:
Building |Tesseractocr| with Visual C++ 2008 Express Edition
============================================================
The Solution file that comes with |Tesseractocr| was created with Visual
Studio 2008, and is compatible for the most part with the free `Visual
C++ 2008 Express Edition
<http://www.microsoft.com/visualstudio/en-us/products/2008-editions/express>`_. You
might, however, sometimes see the following error message::
Fatal error RC1015: cannot open include file 'afxres.h'
.. _version-resource:
The Solution uses resource files to set application and DLL properties
that are visible on Windows 7 when you right-click them in Windows
Explorer, choose :menuselection:`Properties`, and look at the
:guilabel:`Details` tab (the :guilabel:`Version` tab on Windows XP).
.. image:: images/dll_properties_details_tab.png
:align: center
:alt: Windows 7 Properties' Details Tab
Unfortunately, the Express Edition doesn't include the Resource
Editor. So in all resource files::
#include "afxres.h"
has to be changed to::
#include "windows.h"
If someone has used the VS2008 Resource Editor to change a `.rc` file
associated with an application or DLL and forgotten to make these
changes before checking the file in, you'll see the above "Fatal error"
message. Simply manually make the change to fix the error.

==================================
Maintaining the VS2008 directory
==================================
This section is geared towards project maintainers of the
`tesseract-3.0x\\vs2008` directory, rather than users of it.
Python 2.7.x (*not* 3.x) is required for this section. The recommended
version is the `latest from ActiveState
<http://www.activestate.com/activepython/downloads>`_.
.. _tesshelper:
The `tesshelper.py` Python script
=================================
`tesshelper.py` performs a number of useful maintenance related
operations on the `tesseract-3.0x\\vs2008` directory. To run it, first
open a Command Prompt window and navigate to the `<tesseract install
dir>\\vs2008` directory.
Then entering the following command::
python tesshelper.py --help
displays the following help message::
usage: tesshelper.py [-h] [--version] tessDir {compare,report,copy,clean} ...
positional arguments:
tessDir tesseract installation directory
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
Commands:
{compare,report,copy,clean}
compare compare libtesseract Project with tessDir
report report libtesseract summary stats
copy copy public libtesseract header files to includeDir
clean clean vs2008 folder of build folders and .user files
Examples:
Assume that tesshelper.py is in c:\buildfolder\tesseract-3.01\vs2008,
which is also the current directory. Then,
python tesshelper .. compare
will compare c:\buildfolder\tesseract-3.01 "library" directories to the
libtesseract Project
(c:\buildfolder\tesseract-3.01\vs2008\libtesseract\libtesseract.vcproj).
python tesshelper .. report
will display summary stats for c:\buildfolder\tesseract-3.01 "library"
directories and the libtesseract Project.
python tesshelper .. copy ..\..\include
will copy all "public" libtesseract header files to
c:\buildfolder\include.
python tesshelper .. clean
will clean the vs2008 folder of all build directories, and .user, .suo,
.ncb, and other temp files.
Generating the documentation
============================
The source files for the documentation you are currently reading are
written in `reStructuredText
<http://docutils.sourceforge.net/rst.html>`_ and processed with the
`Sphinx Python Documentation Generator
<http://sphinx.pocoo.org/index.html>`_.
To install Sphinx, go to your `<python.2.7.x install dir>\\scripts`
directory and just do::
easy_install -U Sphinx
which will download Sphinx and all its dependencies. [Note: This might
*not* install the Python Imaging Library. If not, then also do
``easy_install -U PIL`` or download it from `here
<http://www.pythonware.com/products/pil/>`__.]
To generate this |Tesseractocr| VS2008 documentation go to
`tesseract-3.0x\\vs2008\\Sphinx` and do::
make clean
make html
Which will create a number of items in
`tesseract-3.0x\\vs2008\\Sphinx\\_build\\html`.
Copy everything there to the distribution's `tesseract-3.0x\\vs2008\\doc`
folder, :bi:`except` for::
.buildinfo
objects.inv
.. _updating-vs2008-directory:
Updating the VS2008 directory for new releases of |Tesseractocr|
================================================================
1. Change the version number strings in
`tesseract-3.0x\\vs2008\\include\\tesseract_versionnumbers.vsprops`.
#. Change the version number in
`tesseract-3.0x\\vs2008\\port\\version.h`.
#. Open up a Command Prompt window, and do the following::
cd <tesseract-3.0x install dir>\vs2008
python tesshelper .. compare
This will list all added and missing items in the `<tesseract-3.0x install
dir>` directories that are used to build `libtesseract`. For the
newly added items ignore::
api\tesseractmain.cpp
api\tesseractmain.h
ccutil\scanutils.cpp
ccutil\scanutils.h
and for the newly missing items ignore::
training\commontraining.cpp
training\commontraining.h
training\tessopt.cpp
training\tessopt.h
#. Open up the `tesseract.sln` in Visual Studio 2008 (or Visual C++ 2008
Express Edition but see :ref:`this
<building-with-vc2008-express>` first).
a. In the Solution Explorer, rename the :guilabel:`libtesseract-3.0x`
Project to the correct version number to make it obvious which
version of |Tesseractocr| this Solution is for.
#. Remove the missing items from the :guilabel:`libtesseract-3.0x` Project.
#. Add the new items to the :guilabel:`libtesseract-3.0x` Project.
If there were a lot of new items, you can use the `newheaders.txt`
and `newsources.txt` files generated by running the
`tesshelper.py` script with the ``compare`` command. Close the
Solution, and then you can directly edit
`libtesseract\\libtesseract.vcproj` to add them to the appropriate
``<Filter> ... </Filter>`` section (either ``Header Files`` or
``Source Files``).
#. With the Solution closed, use a text editor to change all the
Project's `.rc` files to reflect the new version.
If you have a program like the *non-free* `PowerGrep
<http://www.powergrep.com/>`_, you can use it to change all the
`.rc` files in one fell swoop.
Alternatively, you can edit the Version resources within Visual
Studio 2008 (but *not* Visual C++ 2008 Express Edition) and then
manually make the changes mentioned :ref:`here
<building-with-vc2008-express>` afterwards.
.. _copying_a_project:
#. If a new training application was added (edit
`tesseract-3.0x\\training\\Makefile.am` and look at the
``bin_PROGRAMS`` variable to see the list), the easiest thing to do
is copy another existing training application Project and manually
change it.
For example, assuming the new training application is
called `new_trainer.exe`, with the Solution closed:
a. Copy the `ambiguous_words` directory to a new directory called
`new_trainer`.
#. Change the `new_trainer\\ambiguous_words.rc` filename to
`new_trainer\\new_trainer.rc`.
#. Change the `new_trainer\\ambiguous_words.vcproj` filename to
`new_trainer\\new_trainer.vcproj`.
#. Edit `new_trainer\\new_trainer.rc` and change all occurrences of
``ambiguous_words`` to ``new_trainer``.
Also change ``FileDescription`` to describe the new application.
#. Open up the |Tesseractocr| Solution file and right-click the
:guilabel:`Solution:'tesseract'` in the Solution Explorer. Choose
:menuselection:`A&dd --> &Existing Project...` from the context
menu and add the `new_trainer\\new_trainer.vcproj` you just
created.
#. Right-click the newly added Project, and choose
:menuselection:`Project Dependencie&s...`.
The :guilabel:`Project Dependencies` Dialog will open. Make sure
that `libtesseract30x` is checked. If you forget this step, Visual
Studio will not automatically link with `libtesseract` and
you'll get lots of "unresolved external symbol" errors.
This actually goes pretty fast. It should only take you a minute or
so to add a new application to the |Tesseractocr| Solution.
#. (Optional?) Edit `vs2008\\Sphinx\\versions.rst` and add a new entry
describing the changes made for this new version.
#. To make your working directory suitable for reposting back to the
|Tesseractocr| SVN repository, you need to ignore all the following:
+ All `LIB_Release`, `LIB_Debug`, `DLL_Release`, `DLL_Debug`
directories
+ All `.suo` files
+ All `.user` files
+ All `.ncb` files
+ `vs2008\\newheaders.txt`
+ `vs2008\\newsources.txt`
Optionally, the `tesshelper.py` script has the ``clean`` command
which will remove the above items. To run it, open a Command Prompt
window and then do::
cd <tesseract-3.0x install dir>\vs2008
python tesshelper .. clean
The script will respond with the following::
Are you sure you want to clean the
"C:\BuildFolder\tesseract-3.0x\vs2008" folder (Yes/No) [No]? yes
Only list the items to be deleted (Yes/No) [Yes]? no
You have to answer ``yes`` and then ``no`` to the prompts. Otherwise
either the script will just exit, or only list the items that will be
removed instead of actually removing them (which is a good thing to
try first just in case).

==========
Overview
==========
The recommended audience for this document are developers who want to
use Microsoft Visual Studio 2008 with `Tesseract-OCR
<http://code.google.com/p/tesseract-ocr/>`_. If you simply want to *run*
`tesseract` or its various language training applications, then see the
`ReadMe <http://code.google.com/p/tesseract-ocr/wiki/ReadMe>`_. You'll
find instructions there on how to download tesseract's Windows
installer.
|Tesseractocr| consists of:
+ `libtesseract` -- the static (or dynamic) library that does all the
actual work. As of February 2012 it consists of 260+ `C++` files
along with 290+ header files.
+ `tesseract.exe` -- the command-line OCR engine. It's built from a
single, small `C++` file that just calls functions in
`libtesseract`. There currently isn't very much documentation on how
to use `tesseract.exe`, but you can look at what's there in the
repository's `doc
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
subdirectory.
+ Language packs -- needed by `tesseract.exe` in order to recognize
particular languages.
.. _training-applications:
+ Language training applications -- used to teach `tesseract.exe` new
languages. Each has their own (very brief) man page in the `doc
<http://code.google.com/p/tesseract-ocr/source/browse/#svn%2Ftrunk%2Fdoc>`_
subdirectory and include:
+ `ambiguous_words.exe` -- generate sets of words Tesseract is likely
to find ambiguous
+ `classifier_tester` -- tests a Tesseract character classifier on
data as formatted for training
+ `cntraining.exe` -- character normalization training
+ `combine_tessdata.exe` -- combine/extract/overwrite Tesseract data
+ `dawg2wordlist.exe` -- convert a Tesseract DAWG to a wordlist
+ `mftraining.exe` -- feature training
+ `shapeclustering.exe` -- shape clustering training
+ `unicharset_extractor.exe` -- extract unicharset from Tesseract
boxfiles
+ `wordlist2dawg.exe` -- convert a wordlist to a DAWG
Their use is described in the `TrainingTesseract3
<http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3>`_
Wiki page.
This document explains how to:
+ :doc:`Setup <setup>` the proper directory structure required to use
the supplied Visual Studio 2008 Solution
* :doc:`Build <building>` `libtesseract`, `tesseract.exe`, and the
training apps
* :doc:`Write <programming>` programs that link with `libtesseract`

=================================
Programming with `libtesseract`
=================================
To use `libtesseract` in your own application you need to include
|Leptonica|\ ’s `allheaders.h`, and |Tesseractocr|\ ’s `baseapi.h` and
`strngs.h`.
|Tesseractocr| uses `liblept` mainly for image I/O, but you can also use
any of |Leptonica|\ ’s *many* image processing functions on ``PIX``,
while at the same time calling ``TessBaseAPI`` methods. See the
`Leptonica documentation <http://tpgit.github.com/UnOfficialLeptDocs/>`_
for more details.
There doesn't seem to be any documentation on `api\\baseapi.h`, but it
has extensive comments. You can also look at the :ref:`APITest` and
:ref:`APIExamples` projects.
See the :ref:`APITest` project for an example of which compiler and
linker settings you need for various build configurations. The easiest
way to begin a new application is to just make a copy of the `APITest`
directory. See :ref:`this step <copying_a_project>` for detailed
instructions (skip the last step about adding :guilabel:`Project
Dependencies`).
If you want to manually set the required settings, then here's the list
of things to do:
1. Add the following :guilabel:`Preprocessor Definitions` when compiling
any files that include `baseapi.h` and you are linking with the
static library versions of `libtesseract`::
USE_STD_NAMESPACE
If you are linking with the DLL versions of `libtesseract` instead
add::
USE_STD_NAMESPACE;TESSDLL_IMPORTS;CCUTIL_IMPORTS;LIBLEPT_IMPORTS
#. Be sure to add the following to :guilabel:`Additional Include
Directories`::
C:\BuildFolder\include
C:\BuildFolder\include\leptonica
C:\BuildFolder\include\tesseract or
<tesseract-3.0x dir> (all its sub-directories that contain header files)
#. Add `C:\\BuildFolder\\lib` to your :guilabel:`Additional Library
Directories`.
#. In the `C:\\BuildFolder\\include` directory are two Visual Studio
Property Sheet files::
tesseract_versionnumbers.vsprops
leptonica_versionnumbers.vsprops
Using `tesseract_versionnumbers.vsprops` (which automatically inherits
`leptonica_versionnumbers.vsprops`) can make it easier to specify the
libraries you need to import. For example, when creating a staticly
linked debug executable you can say::
zlib$(ZLIB_VERSION)-static-mtdll-debug.lib
libpng$(LIBPNG_VERSION)-static-mtdll-debug.lib
libjpeg$(LIBJPEG_VERSION)-static-mtdll-debug.lib
giflib$(GIFLIB_VERSION)-static-mtdll-debug.lib
libtiff$(LIBTIFF_VERSION)-static-mtdll-debug.lib
liblept$(LIBLEPT_VERSION)-static-mtdll-debug.lib
libtesseract$(LIBTESS_VERSION)-static-debug.lib
to make your application less dependent on library version numbers.
To add the Property Sheet to a Project, open its :guilabel:`Properties
Pages` Dialog, and set the :guilabel:`Configuration Properties |
General | Inherited Project Property Sheets` item to::
..\..\..\include\tesseract_versionnumbers.vsprops
Choosing :menuselection:`&View --> Oth&er Windows --> Property
&Manager` from the menubar will let you see the Properties attached
to each Project's configurations.
.. note::
The DLL versions of |libtess| currently only export the
``TessBaseAPI`` C++ class from `baseapi.h`, there is no C function
interface yet.
.. note::
The DLL versions of `libtesseract` currently only export the
``TessBaseAPI`` and ``STRING`` classes. In theory, all you need is
are those classes. However, if you find yourself having to manipulate
other "internal" tesseract objects then you currently have to link
with the **static library** versions of `libtesseract`.
.. warning::
The Release versions of |liblept|, by design, *never* print out any
possibly helpful messages to the console. Therefore, it is highly
recommended that you do your initial development using the Debug
versions of |liblept|. See `Compile-time control over stderr output
<http://tpgit.github.com/UnOfficialLeptDocs/leptonica/README.html#compile-time-control-over-stderr-output>`_
for details.
<<<Need to add the URL of the zip file that contains include & lib
directory contents for those people who don't want to build libtesseract
themselves>>>
Debugging Tips
==============
Before debugging programs written with `libtesseract`, you should first
download the latest Leptonica sources (currently
`leptonica-1.68.tar.gz`) and VS2008 source package (`vs2008-1.68.zip`)
from:
+ http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68.tar.gz
+ http://code.google.com/p/leptonica/downloads/detail?name=vs2008-1.68.zip
Unpack them to `C:\\BuildFolder` to get the following directory structure::
C:\BuildFolder\
include\
lib\
leptonica-1.68\
vs2008\
tesseract-3.02\
vs2008\
testing\
tessdata\
(see `Building the liblept library
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-liblept.html>`_
for more information)
|Tesseractocr| uses |Leptonica| "under the hood" for all (most? some?)
of its image processing operations. Having the source available (and
compiling it in debug mode) will make it easier to see what's really
going on.
You might want to add
`C:\\BuildFolder\\leptonica-1.68\\vs2008\\leptonica.vcproj` and
`C:\\BuildFolder\\tesseract-3.02\\vs2008\\libtesseract\\libtesseract.vcproj`
to your solution by right-clicking it and choosing :menuselection:`A&dd -->
&Existing Project...`. This seems to make VS2008's Intellisense `work
better
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/building-other-programs.html#intellisense-and-liblept>`_
when finding "external" source files.
Definitely create a ``TESSDATA_PREFIX``x environment variable so that it
contains the absolute path of the directory that contains the
``tessdata`` directory. Otherwise you'll have to put a ``tessdata``
directory in every temporary build folder which quickly becomes painful
(especially since tessdata has gotten very big --- 600MB!).
.. _APITest:
APITest Sample
==============
The :guilabel:`APITest` Solution contains the minimal settings needed to
link with `libtesseract`. It demonstrates the typical situation, where
the "external" application's source files reside *outside* of the
`tesseract-3.0x` directory tree.
To build the `vs2008\\APITest` Solution, first copy it to your
`C:\\BuildFolder` directory. This should now look like::
C:\BuildFolder\
include\
leptonica\
tesseract\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib

liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtesseract302.dll
libtesseract302.lib
libtesseract302d.dll
libtesseract302d.lib
libtesseract302-static.lib
libtesseract302-static-debug.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
tesseract-3.02\
APITest\
baseapitester\
baseapitester.cpp
baseapitester.rc
baseapitester.vcproj
resource.h
stdafx.cpp
stdafx.h
targetver.h
APITest.sln
The :guilabel:`APITest` contains just the :guilabel:`baseapitester`
project. This was created using the VS2008 :guilabel:`Win32 Console
Application` Project Wizard and then just copying most of
`tesseractmain.cpp` and making minor edits. Its settings correctly refer
to the "public" `include` and `lib` directories using relative paths.
It assumes that the `C:\\BuildFolder\\include` directory has been
properly setup. See :ref:`this <copying-headers>` for more details.
The `C:\\BuildFolder\\lib` directory will automatically get
`libtesseract` copied to it whenever it is built.
The `include\\tesseract_versionnumbers.vsprops` Property Sheet is used
to avoid explicit library version number dependencies. Precompiled
headers are used. :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug` build configurations
are supported.
The following are the compiler command lines and linker options
used. See `Compiling a C/C++ Program | Compiler Options
<http://msdn.microsoft.com/en-us/library/9s7c9wdw(v=vs.90).aspx>`_ for a
detailed explanation of these options.

APIExamples
===========
<<<NEEDS WORK>>>
Currently two Projects are in this solution:
+ preprocessing -- Demonstrates how to use |Leptonica|\ ’s image
processing functions to clean up images *before* calling
``TessBaseAPI::SetImage()``.
+ getinfo -- Demonstrates calling various ``TessBaseAPI`` methods to get
back information on the OCR process.
|Tesseractocr| preprocessor definitions
=======================================
``HAVE_CONFIG_H``
Only defined when building under Linux. This causes the inclusion of
`config_auto.h`, which is only auto-generated during the `./configure`
process and thus *not* visible on Windows.
This is what sets the ``VERSION`` macro (and lots of other
configuration related macros).
``TESSDLL_EXPORTS``
Only used when *building* DLL versions of |libtess|.
``TESSDLL_IMPORTS``
Should be defined when building apps that link to a DLL version of
|libtess|. Used as follows in `baseapi.h`::
#ifdef TESSDLL_EXPORTS
#define TESSDLL_API __declspec(dllexport)
#elif defined(TESSDLL_IMPORTS)
#define TESSDLL_API __declspec(dllimport)
#else
#define TESSDLL_API
#endif
If you don't define this then you'll get "undefined external symbol"
errors.
``TESSDLL_API``
Used to mark classes for export (visibility) in DLL versions of
|libtess|. Currently *only* used with the ``TestBaseAPI`` class.
``CCUTIL_EXPORTS``
Only used when *building* DLL versions of |libtess|.
``CCUTIL_IMPORTS``
Should be defined when building apps that link to a DLL version of
|libtess|. Used as follows in `strngs.h`::
#ifdef CCUTIL_EXPORTS
#define CCUTIL_API __declspec(dllexport)
#elif defined(CCUTIL_IMPORTS)
#define CCUTIL_API __declspec(dllimport)
#else
#define CCUTIL_API
#endif
If you don't define this then you'll get "undefined external symbol STRING"
errors.
``LIBLEPT_IMPORTS``
Should be defined when building apps that link to a DLL version of
|Leptonica|. Used as follows in environ.h::
#if defined(LIBLEPT_EXPORTS) || defined(LEPTONLIB_EXPORTS)
#define LEPT_DLL __declspec(dllexport)
#elif defined(LIBLEPT_IMPORTS) || defined(LEPTONLIB_IMPORTS)
#define LEPT_DLL __declspec(dllimport)
#else
#define LEPT_DLL
#endif
If you don't define this then you'll get "undefined external symbol"
errors.
``USE_STD_NAMESPACE``
Causes the following to be done::
#ifdef USE_STD_NAMESPACE
using std::string;
using std::vector;
#endif
``_WIN32``
Used to indicate that the build target is Windows 32-bit or
64-bit (``WIN32`` and ``WINDOWS`` are also added by the New Project
Wizards).
See `C/C+ Preprocessor Reference | The Preprocessor | Macros |
Predefined Macros
<http://msdn.microsoft.com/en-us/library/b0084kay(v=vs.90).aspx>`_ for
the complete list for Visual Studio 2008.
``_MSC_VER``
Used to check specifically for building with the VC++ compiler (as
opposed to the MinGW gcc compiler).
``_USRDLL``
Only defined when building the DLL versions of `libtesseract`.
``_MBCS``
Automatically defined when :guilabel:`Configuration Properties |
General | Character Set` is set to :guilabel:`Use Multi-Byte
Character Set`.
``DLLSYM``
`Obsolete
<http://groups.google.com/group/tesseract-dev/msg/5e0f7f7fab27b463>`_

===========================
Setting up |Tesseractocr|
===========================
The Visual Studio 2008 Solutions included with |Tesseractocr|, rely on
*relative paths* to reference files and directories --- including
locations that are *outside* of the `tesseract-3.0x` tree. It is
therefore vitally important to correctly set up the directories for the
various components. This section describes how to do this.
.. _directory-setup:
Initial "Build" directory setup
===============================
First create an empty directory where you will unpack all the required
downloads. Assume you call this directory `C:\\BuildFolder`.
.. _download-leptonica:
1. Download the |Leptonica| 1.68 pre-built binary package
(`leptonica-1.68-win32-lib-include-dirs.zip`) from:
http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68-win32-lib-include-dirs.zip
and unpack it to `C:\\BuildFolder`.
2. |Leptonica|, even on Windows as of v1.68, still requires a few unix
utilities (like `rm`, `diff`, `sleep`). The easiest way to deal with
this is to follow the instructions at `Installing Cygwin coreutils
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html>`_.
At this point, if all you want to do is link with `libtesseract` you can
`download <http://code.google.com/p/tesseract-ocr/downloads/list>`_ the
file that just contains the "public" |Tesseractocr| headers along with
the precompiled library binaries for Windows. Unpack it to
`C:\\BuildFolder` and you'll now have::
C:\BuildFolder\
include\
leptonica\
tesseract\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll-debug.lib
libjpeg8c-static-mtdll.lib
liblept168-static-mtdll-debug.lib
liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtesseract302.dll
libtesseract302.lib
libtesseract302d.dll
libtesseract302d.lib
libtesseract302-static.lib
libtesseract302-static-debug.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
and you can skip the rest of this page and go directly to
:doc:`programming`.
The recommended action, however, is to download the |Tesseractocr|
sources and build them yourself. Therefore...
3. Download the |Tesseractocr| Visual Studio 2008 source files from the
`downloads page
<http://code.google.com/p/tesseract-ocr/downloads/list>`_. If, for
example, you'd like to build v3.02 you would use the following link:
http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-ocr-3.02-vs2008.zip
Unpack the file to `C:\\BuildFolder`
You would now have the following directory structure::
C:\BuildFolder\
include\
leptonica\
leptonica_versionnumbers.vsprops
tesseract_versionnumbers.vsprops
lib\
giflib416-static-mtdll-debug.lib
giflib416-static-mtdll.lib
libjpeg8c-static-mtdll-debug.lib
libjpeg8c-static-mtdll.lib
liblept168-static-mtdll-debug.lib
liblept168-static-mtdll.lib
liblept168.dll
liblept168.lib
liblept168d.dll
liblept168d.lib
libpng143-static-mtdll-debug.lib
libpng143-static-mtdll.lib
libtiff394-static-mtdll-debug.lib
libtiff394-static-mtdll.lib
zlib125-static-mtdll-debug.lib
zlib125-static-mtdll.lib
tesseract-3.02\
vs2008\
ambiguous_words\
classifier_tester\
cntraining\
combine_tessdata\
dawg2wordlist\
doc\
include\
libtesseract\
libtesseract.vcproj
mftraining\
port\
shapeclustering\
sphinx\
tesseract\
tesseract.vcproj
unicharset_extractor\
wordlist2dawg\
tesseract.sln
tesshelper.py
4. Download the |Tesseractocr| source files for the same version as the
VS2008 files you just unpacked. In this case, the proper link would
be:
http://code.google.com/p/tesseract-ocr/downloads/detail?name=tesseract-3.02.tar.gz
Unpack the file to `C:\\BuildFolder`
This will add a bunch of directories to your already existing
`C:\\BuildFolder\\tesseract-3.0x` directory. You should now have (for
v3.02)::
C:\BuildFolder\
include\
leptonica\
lib\
tesseract-3.02\
api\
ccmain\
ccstruct\
ccutil\
classify\
config\
contrib\
cube\
cutil\
dict\
doc\
image\
java\
image\
neural_networks\
tessdata\
testing\
textord\
training\
viewer\
vs2008\
wordrec\
.. _copying-headers:
If you are planning on writing applications that link with
|Tesseractocr|, and you don't want to add all the `tesseract-3.0x`
directories to your project's list of ``include`` directories, then do
this additional step:
5. Copy all the required headers to the "public" include folder.
If you already have a `C:\\BuildFolder\\include\\tesseract`
directory you should delete it in case some of the files have been
removed.
Then use the python `tess-helper.py` script to copy (possibly updated
versions of) the required headers by doing::
cd C:\BuildFolder\tesseract-3.02\vs2008
python tesshelper.py .. copy ..\..\include
See :ref:`tesshelper` for more details.
You are now ready to :doc:`build <building>` |Tesseractocr| using Visual
Studio 2008.
.. _using-latest-sources:
Using the latest |Tesseractocr| sources
=======================================
If you'd like to try the absolute latest version of |Tesseractocr|,
here's how to download the source files from its SVN repository:
1. Follow Steps 1 and 2 :ref:`above <directory-setup>`.
#. `Checkout <http://code.google.com/p/tesseract-ocr/source/checkout>`_
the |Tesseractocr| sources to a directory on your computer. This
directory should :bi:`not` be `C:\\BuildFolder`!
If you are unfamiliar with `SVN <http://subversion.apache.org/>`_,
the easiest way to do this is to first download and install
`TortoiseSVN <http://tortoisesvn.net/>`_ and then:
a. Right-click the (empty) directory where you want the working copy
and choose :menuselection:`SVN Chec&kout...` from
the pop-up menu.
#. Enter ``http://tesseract-ocr.googlecode.com/svn/trunk/`` for
:guilabel:`&URL of repository`. You can keep all the other
settings at their defaults.
.. image:: images/tortoisesvn_checkout.png
:align: center
:alt: TortoiseSVN Checkout Dialog Box
#. Click the :guilabel:`&OK` button to commence downloading the
|Tesseractocr| sources to your computer. This might take a while as
the language data in the `tessdata` directory is quite large. As
of February 2012, about 335MB needs to be transferred for the
initial checkout. The total size of the resulting working copy is
about 1.2GB.
#. Keeping your working copy up to date after this is as simple as
right-clicking its directory and choosing :menuselection:`SVN
&Update`. Unlike the initial checkout, this will usually finish
very quickly.
#. Copy the :bi:`contents` of your working directory, except for the
`tessdata` directory, to `C:\\BuildFolder\\tesseract-3.0x`, where
``x`` should probably be the latest stable release + ``alpha``,
``beta``, etc.
#. Optionally, follow Step 5 from :ref:`above <copying-headers>`.
#. You'll probably want to set an environment varible named
``TESSDATA_PREFIX`` to point at your working copy directory (since
that now contains the latest `tessdata` directory).
#. If someone hasn't already done so, you have to proceed to
:ref:`updating-vs2008-directory`. You can skip all the steps that
relate to updating the version number. Otherwise, depending on how
many changes have been made since the last stable release, you may
have little or no work to do.

==================
Handy free tools
==================
`TortoiseSVN <http://tortoisesvn.net/>`_
----------------------------------------
The |Tesseractocr| source lives in an SVN repository at `Google Code
<http://code.google.com/p/tesseract-ocr/source/checkout>`_, so to
:ref:`build the latest versions <using-latest-sources>` you'll need to
know SVN. For newcomers (or not), TortoiseSVN (http://tortoisesvn.net/)
is a great alternative to the SVN command line interface.
"TortoiseSVN is an easy-to-use SCM / source control software for
Microsoft Windows and possibly the best standalone Apache Subversion
client there is. It is implemented as a Windows shell extension, which
makes it integrate seamlessly into the Windows explorer. Since it's not
an integration for a specific IDE you can use it with whatever
development tools you like."
`JP Software TCC/LE <http://jpsoft.com/tccle_cmd_replacement.html>`_
--------------------------------------------------------------------
Instead of using Windows' plain old Command Prompt window --- and less
intimidating than using the bash shell from `cygwin
<http://cygwin.com/>`_ or `MSYS <http://mingw.org/wiki/msys>`_ --- the
"TCC/LE - Windows CMD Replacement Command Console" by JP Software is
definitely worth trying. It is available at
http://jpsoft.com/tccle_cmd_replacement.html.
For example, to look for all the settable options in |Tesseractocr|,
try::
C:\BuildFolder\tesseract-3.02\
ffind /s/v/c/t"_MEMBER" *.cpp | list/s
and you'll get something that looks like this in the `list` viewer::
---- C:\BuildFolder\tesseract-3.02\ccmain\tesseractclass.cpp
: BOOL_MEMBER(tessedit_resegment_from_boxes, false,
BOOL_MEMBER(tessedit_resegment_from_line_boxes, false,
BOOL_MEMBER(tessedit_train_from_boxes, false,
BOOL_MEMBER(tessedit_make_boxes_from_boxes, false,
BOOL_MEMBER(tessedit_dump_pageseg_images, false,
...
double_MEMBER(segsearch_max_char_wh_ratio, 2.0,
double_MEMBER(segsearch_max_fixed_pitch_char_wh_ratio, 2.0,
BOOL_MEMBER(save_alt_choices, false,
413 lines in 7 files
(Press the :kbd:`Escape` key to exit the `list` viewer).
The equivalent(?) Linux incantation, copied and slightly modified from
the grep info, is::
find . -name '*.cpp' -print0 | xargs -0r grep -H '_MEMBER' | less
Note: You can also do this directly in Visual Studio 2008, by choosing
:menuselection:`&Edit --> &Find and Replace --> F&ind in Files`
(:kbd:`Ctrl+Shift+F`), so maybe this wasn't the best example:
.. image:: images/find_in_files.png
:align: center
:alt: Visual Studio 2008 Find in Files Dialog
`Cygwin <http://cygwin.com/>`_
------------------------------
"`Cygwin <http://cygwin.com/>`_ is a collection of tools which provide a
Linux look and feel environment for Windows."
|Leptonica| actually still requires a few unix utilities (like `rm`,
`diff`, `sleep`) for some operations and might silently fail if it they
not present (as of v1.68). The easiest way to deal with this is to
`install Cygwin
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-cygwin.html>`_
or MSYS (see the next section).
`MSYS <http://mingw.org/wiki/msys>`_
------------------------------------
"`MSYS <http://mingw.org/wiki/msys>`_ is a collection of GNU utilities
such as bash, make, gawk and grep to allow building of applications and
programs which depend on traditionally UNIX tools to be present. It is
intended to supplement MinGW and the deficiencies of the cmd shell."
WinDiff
-------
An important phase of testing `tesseract` is checking how its output
compares to previous runs (or ground-truth files). A visual diff program
can make that easier.
Microsoft's WinDiff doesn't seem to come with Visual Studio
anymore. However it can still be downloaded from `Grig Software
<http://www.grigsoft.com/download-windiff.htm>`_ (without having to get
all the other stuff in the `Windows XP Service Pack 2 Support Tools
<http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=18546>`_.
Other options are `KDiff3 <http://kdiff3.sourceforge.net/>`_ and
`ExamDiff <http://www.prestosoft.com/edp_examdiff.asp>`_ (`ExamDiff Pro
<http://www.prestosoft.com/edp_examdiffpro.asp>`_ is also recommended
but it's not free).
KDiff3 doesn't seem to correctly auto-detect UTF-8 encodings so choose
:menuselection:`&Settings --> &Configure KDiff3...` from the menubar and
set the :guilabel:`Regional Settings` tab as follows:
.. image:: images/kdif3_settings.png
:align: center
:alt: KDiff3 Regional Settings
Also on the :guilabel:`Integration` tab, make sure that :guilabel:`Quit
also via Escape key` is turned on (checked). Since IrfanView also quits
when you press the :kbd:`Esc` key, this just makes it easy to dismiss
both applications with the same key.
Here is KDiff3 showing the (slight) difference in OCR results after
deskewing a grayscale image:
.. figure:: images/sample_diff.png
:height: 512
:align: center
:alt: Diff in OCR after deskewing image
:target: _images/sample_diff.png
`Click for larger image <_images/sample_diff.png>`__
`IrfanView <http://www.irfanview.com/>`_
----------------------------------------
You need some program to view the images you are trying to OCR and since
|Leptonica| uses IrfanView (http://www.irfanview.com/) to `automatically
display images <http://tpgit.github.com/UnOfficialLeptDocs/vs2008/installing-irfanview.html>`_,
you might as well use it also.
"IrfanView is a very fast, small, compact and innovative FREEWARE (for
non-commercial use) graphic viewer for Windows 9x, ME, NT, 2000, XP,
Vista, Windows 7."
Pressing the :kbd:`I` key while viewing an image with IrfanView, will
bring up a dialog box that shows most of its important properties (like
bits/pixel and DPI).
`Aware Systems AsTiffTagViewer <http://www.awaresystems.be/imaging/tiff/astifftagviewer.html>`_
-----------------------------------------------------------------------------------------------
This utility, available at
http://www.awaresystems.be/imaging/tiff/astifftagviewer.html, let's you
easily determine TIFF image file properties.
"Whenever a customer reports your software doesn't handle this or that
particular TIFF, use AsTiffTagViewer and discover why."
`Dependency Walker <http://dependencywalker.com/>`_
---------------------------------------------------
If you're having problems with missing module runtime errors, the
Dependency Walker (http://dependencywalker.com/) usually can help track
down the problem.
"Dependency Walker is also very useful for troubleshooting system errors
related to loading and executing modules. Dependency Walker detects many
common application problems such as missing modules, invalid modules,
import/export mismatches, circular dependency errors, mismatched machine
types of modules, and module initialization failures."
You probably want the 32-bit version even if you are running on a
Windows 64-bit platform, because the current VS2008 Solution for
|Tesseractocr| by default builds a 32-bit app. From the `FAQ
<http://dependencywalker.com/faq.html>`_
"There are 32-bit and 64-bit versions Dependency Walker. All versions
are capable or opening 32-bit and 64-bit modules. However, there are
major advantages to using the 32-bit Dependency Walker to process 32-bit
modules and the 64-bit Dependency Walker to process 64-bit modules.
This is especially true when running on a 64-bit version of Windows,
which allows execution of both 32-bit and 64-bit programs. The 32-bit
subsystem on 64-bit Windows (known as "WOW64") has its own private
registry, "AppPaths", "KnownDlls", system folders, and manifest
processing. Only the 32-bit version of Dependency Walker can access
this 32-bit environment, which is needed to accurately process a 32-bit
module. Likewise, only the 64-bit version of Dependency Walker can
fully access the 64-bit environment, so it should always be used for
processing 64-bit modules."

The above image shows Dependency Walker used on
`tesseract-dlld.exe`. The panes show the `DLL`\ s that it is dependent
on, the methods it actually uses from `libtesseract302d.dll`, and all
the exported methods from `libtesseract302d.dll`. Using this it's easy
to see that only the ``TessBaseAPI`` and ``STRING`` classes are exported
as mentioned in :doc:`programming`.
`Sysinternals Process Explorer <http://technet.microsoft.com/en-us/sysinternals/bb896653>`_
-------------------------------------------------------------------------------------------
Another essential program to help figure out what your program is doing
is Process Explorer
(http://technet.microsoft.com/en-us/sysinternals/bb896653).
"The unique capabilities of Process Explorer make it useful for tracking
down DLL-version problems or handle leaks, and provide insight into the
way Windows and applications work."
`VMware Player <http://www.vmware.com/products/player/>`_
---------------------------------------------------------
VMware Player (http://www.vmware.com/products/player/) can be used to
install, for example, `Ubuntu 11.10 <http://www.ubuntu.com/>`_ in a
virtual machine on Windows and see how the other half lives. It also
helps when trying to figure out if the Windows version of `tesseract`
acts the same way as the "original" version.
"VMware Player is the easiest way to run multiple operating systems at
the same time on your PC. With its user-friendly interface, VMware
Player makes it effortless for anyone to try out Windows 8 developer
release, Windows 7, Chrome OS or the latest Linux releases, or create
isolated virtual machines to safely test new software and surf the Web."

Version Notes
===============
3.02 -- February ??, 2012
=========================
+ Created a completely new Visual Studio 2008 solution from scratch.
+ Added 64 new source files and removed the following deleted files
(relative to v3.01):
+ ccutil\memblk.cpp
+ ccutil\memblk.h
+ ccutil\memryerr.h
+ wordrec\pieces.h
+ wordrec\tally.cpp
+ wordrec\tally.h
+ Created :guilabel:`LIB_Release`, :guilabel:`LIB_Debug`,
:guilabel:`DLL_Release`, and :guilabel:`DLL_Debug` build
configurations.
+ Created a single `libtesseract` library and removed generation of the
twelve sub-libraries.
+ Used references to `leptonica_versionnumbers.vsprops` and
`tesseract_versionnumbers.vsprops` Property Sheets, which define
version number "user macros", in all Visual Studio Projects. These are
also copied to `C:\\BuildFolder\\include`, so you can refer to them in
your own projects. By using the new ``*_VERSION`` macros, you'll be
isolated from worrying about version number changes in the library
filenames.
See :ref:`APITest's <APITest>` :ref:`LIB_Release <apitest-lib-release>` Linker
:guilabel:`Additional Dependencies` settings for an example of what
this looks like in practice.
See |Leptonica|\ ’s explanation `About version numbers in library
filenames
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/downloading-binaries.html#about-version-numbers>`_
for more details.
+ Added a :ref:`Version Resource <version-resource>` to all DLLs and
applications.
+ Removed inclusion of the |Leptonica| libraries. They now have to be
:ref:`downloaded separately <download-leptonica>`.
+ Changed to a :ref:`Build directory structure <directory-setup>` that
is compatible with |Leptonica| and allows the building of
|Tesseractocr|\ -based applications using only the `include` and `lib`
directories.
+ The `libtesseract` libraries are now named as follows:
static libraries:
+ libtesseract302-static.lib
+ libtesseract302-static-debug.lib
DLLs:
+ libtesseract302.lib (import library)
+ libtesseract302.dll
+ libtesseract302d.lib (import library)
+ libtesseract302d.dll
+ Used compiler and linker settings based on the |Leptonica| `VS2008
Developer package
<http://tpgit.github.com/UnOfficialLeptDocs/vs2008/index.html>`_.
+ Removed all preprocessor defines of ``__MSW32__`` which is no longer
needed.
+ Removed `vs2008\include\stdint.h` which is no longer required to build
|liblept|.
+ Removed `vs2008\include\inttypes.h` which isn't needed to build
|liblept|.
+ Turned off the following compiler warnings::
/wd4005: 'snprintf' : macro redefinition
/wd4018 'expression' : signed/unsigned mismatch
/wd4099 type name first seen using 'class' now seen using 'struct'
/wd4244 conversion from 'double' to 'float', possible loss of data
/wd4267 conversion from 'size_t' to 'type', possible loss of data
/wd4305 truncation from 'type1' to 'type2'
/wd4355 'this' : used in base member initializer list
/wd4566 character represented by universal-character-name x cannot
be represented in the current code page
/wd4800 forcing value to bool 'true' or 'false' (performance warning)
/wd4996 'function': was declared deprecated
+ Used the "C7 Compatible" Debug Information (/Z7) compiler switch,
which puts the debugging information in the .obj files. That way we
don't have to worry about also supplying `.pdb` files. See `/Z7,
/Zi, /ZI (Debug Information Format)
<http://msdn.microsoft.com/en-us/library/958x11bc(VS.90).aspx>`_ for
more information.
+ Added Projects for the following new :ref:`training applications
<training-applications>`:
+ ambiguous_words
+ classifier_tester
+ dawg2wordlist
+ shapeclustering
+ Moved `mathfix.h` from `vs2008\\include` to the `vs2008\\port`
directory.
+ Removed Visual Studio 2010 support. See :doc:`vs2010-notes` for the
rationale.
+ Created a python script called :ref:`tesshelper.py <tesshelper>`, that
eases some maintenance tasks related to releasing future VS2008
Solutions.
+ The list of "public" header files that are required to build
"external" applications is now limited to the following 13 files::
api\apitypes.h
api\baseapi.h
ccmain\thresholder.h
ccstruct\publictypes.h
ccutil\errcode.h
ccutil\fileerr.h
ccutil\host.h
ccutil\memry.h
ccutil\platform.h
ccutil\serialis.h
ccutil\strngs.h
ccutil\tesscallback.h
ccutil\unichar.h
