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

bc95798e01 Implement a new orientation and script detection API for C and C++ 
See issue #424.

The existing C API for TessBaseAPIDetectOS requires a C caller to successfully allocate struct OSResults which is actually a C++ class.  Generally it won't
be possible for a regular C compiler to do this properly.

It's also assumed that most API level users of Tesseract are only interested in Tesseract's best guess as to script and orientation, not the individual values for all possible scripts.

This introduces a new API with a better name that is more closely aligned with the output of 'tesseract -psm 0'.  Both tesseract -psm 0 and this API now share the same code in baseapi.cpp.

caffb3133b Remove unneeded 'struct' from TessBaseAPI::GetHOCRText (issue #414) 
It conflicts with a previous 'class' declaration for ETEXT_DESC:

 Struct 'ETEXT_DESC' was previously declared as a class

53fc4456cc Fixed issue 1252: Refactored LearnBlob and its call hierarchy to make it a member of Classify. 
Eliminated the flexfx scheme for calling global feature extractor functions
through an array of function pointers.
Deleted dead code I found as a by-product.
This CL does not change BlobToTrainingSample or ExtractFeatures to be full
members of Classify (the eventual goal) as that would make it even bigger,
since there are a lot of callers to these functions.
When ExtractFeatures and BlobToTrainingSample are members of Classify they
will be able to access control parameters in Classify, which will greatly
simplify developing variations to the feature extraction process.
