a18620cfea Improved results on images with no resolution. Estimates resolution 
from the size of the connected components, based on average text size.

cc0d87c5b8 List available languages recursively 
Tesseract supports hierarchies of languages and uses them since
the new files best/*.traineddata were added.

Now `tesseract --list-langs` also shows any traineddata files in
subdirectories of the tessdata directory.

0720b3f38b Change default resolution from 70 to 300 dpi 
The default resolution is used for images without an explicit resolution
or with an unreasonable resolution (smaller than 70 or larger than 2400).

1cf8fe51a0 Remove mathfix.h 
It was only needed for MS Visual Studio 2012 and older.
Those compilers are not supported for Tesseract.

5e3665c6ae Remove most libtiff dependencies 
libtiff is no longer needed for OpenCL, so remove that dependency.

It is still suggested for Windows to redirect warning messages
from the tesseract executable to the console.

1cc511188d Added extra Init that takes a memory buffer or a filereader function pointer to enable read of traineddata from memory or foreign file systems. Updated existing readers to use TFile API instead of FILE. This does not yet add big-endian capability to LSTM, but it is very easy from here. 2017-04-27 15:48:23 -07:00
