Matthew Caruana Galizia updated TIKA-2174:
------------------------------------------
Description:
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.
