Где я могу найти список доступных имен свойств для первого параметра функции tesseract->setvariable?
из множества вытаращенных глаз я могу найти только несколько из них, как приведенный ниже пример для setVariable Тессеракта (1-й парам, 2-й парам)
tesseract->SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ");
tesseract->SetVariable("language_model_penalty_non_freq_dict_word", "0");
tesseract->SetVariable("language_model_penalty_non_dict_word", "0");
tesseract->SetVariable("tessedit_char_blacklist", "xyz");
tesseract->SetVariable("classify_bln_numeric_mode", "1");
Я хотел бы знать, сколько их еще там?
есть ли список? Если есть, пожалуйста, дайте мне ссылку на него.

этот код должен сделать трюк для iOS... возможно, потребуется немного подправить.
bool verboseOut = true;
if (verboseOut) { //Write to console current Settings
char buffer [256];
FILE * pFile = tmpfile();
tesseract->PrintVariables(pFile);
rewind(pFile);
while (!feof(pFile)) {
if (fgets (buffer,256,pFile))
fputs (buffer,stdout);
} fclose(pFile);
}
