Tyler Palsulich commented on TIKA-93:
-------------------------------------
Hi [~twigbranch]. OCR is not currently run on embedded images by default. You
can see an example (in Java) of enabling OCR on embedded images in the
TesseractOCRTest. So, tika-app currently will only run OCR on direct image
files. Have you tried that?

> I don't know of any decent open source pure Java OCR libraries, but there are
> command line OCR tools like Tesseract
> (http://code.google.com/p/tesseract-ocr/) that could be invoked by Tika to
> extract text content (where available) from image files.
