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.
