LSTMTrainer is only used for training, so the shared library for
Tesseract can be made smaller.

bd13069fe8 Simplify class LSTMTrainer 
The function pointers and callbacks file_reader_, file_writer_,
checkpointer_reader_ and checkpoint_writer_ are always set to
the same values. Replacing them by direct function calls
simplifies the code and allows removing more code from tesscallback.h.

3871caae86 Simplify indirect call of LMPainPoints::GeneratePainPoint 
It does neither need a temporary TessResultCallback2 nor the function
LMPainPoints::GenerateForBlamer.

This also allows removing more code from tesscallback.h.

Fix text2image compilation on C++17 compilers
 2019-06-14 07:45:14 +02:00
James R. Barlow
a9890afd12 Fix text2image compilation on C++17 compilers 
C++17 drops support for `std::random_shuffle`, breaking C++17 compilers
that run to compile text2image.cpp. std::shuffle is valid on C++11
through C++17, so use std::shuffle instead.

Due to the use `std::random_shuffle`, `text2image --render_ngrams`
would not give consistent results for different compilers or platforms.
With the current change, the same random number generator is used for
all platforms and initialized to the same seed, so training output
should be consistent.
