Here you have a snippet of that. If someone wants to put this in the wiki,
I could improve it a little (better comments, etc.). Just let me know.
cv::Mat image = cv::imread(file_path , 0); // image should be 8
bpp, 1 channel std::string lang = "my_trained_file"; // file on
disk is "my_trained_file.traineddata" tesseract::TessBaseAPI
tess_api; tess_api.Init("./", lang.c_str(),
tesseract::OEM_DEFAULT);
tess_api.SetPageSegMode(static_cast<tesseract::PageSegMode>(7)); //
using 7 here, see available modes in tesseractmain.cpp or here

tess_api.TesseractRect( image.data, 1, image.step1(), 0, 0,
image.cols, image.rows); const char *txt = tess_api.GetUTF8Text();
char *boxes = tess_api.GetBoxText(0);
