Luis Filipe Nassif commented on TIKA-2473:
------------------------------------------
Hi [~mcaruanagalizia],
I think jbig2 is handled internally in pdfbox and no image conversion is done
by Tika. If we want to do that, I think the conversion could be called from
TesseractOCRParser.
> PCX and DCX image support

> Key: TIKA-2473
> URL: https://issues.apache.org/jira/browse/TIKA-2473
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.16
> Reporter: Matthew Caruana Galizia
> Priority: Major
>
> It's straightforward in theory to implement support for PCX and DCX. There's
> support for it in Commons Imaging as well as in ImageIO via TwelveMonkeys.
> In practise, however, I'm not really sure how implement support. We obviously
> want to OCR the images, but Tesseract has no support for the format. So where
> do we do the conversion to a BufferedImage? I tried to look for what is done
> to handle JBIG2 files but I can't find that anywhere.
