Tim Allison updated TIKA-1994:
------------------------------
Description:
Users can now run OCR on individual images embedded inline in PDFs if they get
the configuration right.
There are some drawbacks: 1) the text appears as an attachment if using the
RecursiveParserWrapper, 2) text may be more cleanly extracted on the fully
rendered page instead of on the individual images (this is still tbd).
It might be useful to run OCR against each rendered page (instead of the
component images).
Integrating OCR is on the roadmap for PDFBox 2.1 (PDFBOX-1912). This will
allow us to experiment with strategies until the cleaner integration is
available with PDFBox 2.1.
