I'm trying to get the actual charset loaded by Tesseract from a .traineddata file. I can call TessBaseAPI::GetUnichar(id++) in a loop but how to find what the maximum acceptable id is? TessBaseAPI::GetUnichar() implementation is just const char* TessBaseAPI::GetUnichar <http://tesseract-ocr.github.io/4.0.0/a01625.html#ga34314bb3635a6e0d171e33d4b4181db2> (int unichar_id) { return tesseract_ <http://tesseract-ocr.github.io/4.0.0/a02186.html#a247f50792f581df05afe336a2aeda402> ->unicharset <http://tesseract-ocr.github.io/4.0.0/a02666.html#a69c5179ac5f10a24f3f97e16ca09460f> .id_to_unichar <http://tesseract-ocr.github.io/4.0.0/a03950.html#aa19fb595808fe4688c580334937dfa45> (unichar_id); }
that in turn calls const char* UNICHARSET::id_to_unichar <http://tesseract-ocr.github.io/4.0.0/a03950.html#aa19fb595808fe4688c580334937dfa45> (UNICHAR_ID <http://tesseract-ocr.github.io/4.0.0/a00605.html#afedceee7ea132dae3d224db2cf8b5618> id) const { if (id == INVALID_UNICHAR_ID) { return INVALID_UNICHAR; } ASSERT_HOST <http://tesseract-ocr.github.io/4.0.0/a00503.html#a93a603f4063a6b9403d81caa245a583b>(id < this->size <http://tesseract-ocr.github.io/4.0.0/a03950.html#adb332692009836a2d89e5fdf63f9765f> ()); return unichars[id].representation; } I assume it will crash if id is out of bounds. And UNICHARSET:: <http://tesseract-ocr.github.io/4.0.0/a03950.html#aa19fb595808fe4688c580334937dfa45>size() is not exposed via TessBaseAPI. Any idea how one could use TessBaseAPI::GetUnichar() to get chars known to Tesseract? -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
