Tim Allison commented on TIKA-2232:
-----------------------------------
Proposed change if jbig2 is not on the classpath:
PDFParser extractInlineImages adds:
{noformat}
X-TIKA:EXCEPTION:warn : org.apache.pdfbox.filter.MissingImageReaderException:
Cannot read JBIG2 image: jbig2-imageio is not installed
at org.apache.pdfbox.filter.Filter.findImageReader(Filter.java:128)
at org.apache.pdfbox.filter.JBIG2Filter.decode(JBIG2Filter.java:54)
{noformat}
to the metadata of the PDF...
ImageParser checks for JBIG2 in {{try{ Class.forName}} before adding jp2 to
{{SUPPORTED_TYPES}}. If jbig2 is not on the cp, then the files are handled by
the EmptyParser, as they used to be.
> Add JBIG2 image parsing support
