Tesseract - change language file location

c++ air ocr tesseract
sydd picture sydd · Aug 5, 2011 · Viewed 19.2k times · Source

I am making an AIR project, which will need some OCR capabilities, so i decided to use tesseract (now i try to get it working on Windows).

My problem is, that can not change the location of the language file - it always tries to look in my Tesseract installation directory (program files (x86)\Tesseract-OCR\tessdata\mylang.traineddata)

Is there a way that i can configure Tesseract to look for this file where i specify? for example in the same folder as tesseract.exe. I dont want (or perhaps event cant) install an application with the AIR installer. I've tried it with the 3.0 version and the latest SVN version.

Thanks

Yes, you can, by setting the TESSDATA_PREFIX environment variable, e.g.:

export TESSDATA_PREFIX=/usr/local/share/

Note that the directory path must end in a /.
