Our products use one of the best Optical Character Recognition (OCR) engines "Tesseract". Tesseract development has been sponsored by Google since 2006.
We developed set of optimizing image procedures for best OCR recognition. These functions provide cardinal improving of the OCR results.
At the same time Tesserract engine may not recognize some specific fonts. The best results may be achieved for standard Microsoft Office fonts with size from 9 to 13 px.
Please pay attention, we use Tesseract OCR as-is and we cannot add support for unrecognized symbols/fonts/languages
