Grant Ingersoll updated TIKA-93:
--------------------------------
Attachment: testOCR.pptx
testOCR.pdf
testOCR.docx
TIKA-93.patch
Not sure if this is progress or not...
The testOCR.* files need to go in the parsers/src/test/resources/test-documents
directory.
Things that changed:
# Moved config to ParseContext instead of one off implementation in
PDFParserConfig.
# Used the existing ParseContext for passing in the OCRParser instead of
separate handling
# Added some more test files. Will upload them.
Things I could use help on:
# Trying to get this integrated into the Office stuff. I see the
DELEGATING_PARSER capabilities for embedded extraction, but not quite sure
about how to best leverage that. See JavaOCRParserTest.testOCR for some
attempts at setting up the test
# Overall, my biggest lack of understanding is around how to configure this
stuff. As I see it, we need to be able to set 2 things:
## The OCRParser or Delegatingparser. I'm not sure how embedded contexts are
used in practice. Note, some of the OCRParser implementations will require
configuration/training before they can be used.
## Whether or not to actually use the OCRParser (a boolean flag), as OCR is
expensive and not everyone will want it for every doc, etc.

> 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.
