Jukka Zitting commented on TIKA-93:
-----------------------------------
OCRopus (http://code.google.com/p/ocropus/) seems like a nice tool for this.
It's a command like tool so we'd need to use something like the ExternalParser
class to use it, but the annotated HTML output it generates is already very
close to what Tika uses, so the integration should be easy.

> Reporter: Jukka Zitting

> I don't know of any decent open source pure Java OCR libraries, but there are
> command line OCR tools like Tesseract

> extract text content (where available) from image files.
