Subject [jira] [Commented] (TIKA-2174) Too few formats in support declared by TesseractOCRParser

Matthew Caruana Galizia commented on TIKA-2174:
-----------------------------------------------

Thank you! I've also confirmed that Tesseract can handle image/x-portable-pixmap (PPM) files,
so perhaps we could add that too?

> A complete install of Leptonica with Tesseract will add support for formats that are
not declared by TesseractOCRParser. These include JP2, JPX and PPM.
> Tesseract produces OCR output fine for JPX images as of this version:
> {noformat}
>   $ tesseract -v
>      tesseract 3.04.01
>        leptonica-1.73
>          libjpeg 8d : libpng 1.6.26 : libtiff 4.0.6 : zlib 1.2.5}}
> {noformat}
> However, these types are not declared by getSupportTypes so no output is produced for
PDFs which contained JPX images of scanned documents, for example.
