Stef Ald commented on TIKA-93:
------------------------------
Just installed tesseract, maven2, and tika on osx 10.9. It looks like the
TesseractOCR parser was installed (3 tests were run, taking about 4 seconds).
When I run "java -jar tika-app/target/tika-app-1.7-SNAPSHOT.jar" on a test PDF
(scanned) the metadata is parsed, but there's no body text. The pdf is only
parsed by the following:
<meta name="X-Parsed-By" content="org.apache.tika.parser.DefaultParser"/>
<meta name="X-Parsed-By" content="org.apache.tika.parser.pdf.PDFParser"/>
Do I need to do something in particular to invoke the tesseract ocr parser?

> 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.
