pdf - Determing unsupported image formats for PDFBox -

-

i have spent few hours trolling through mailing lists , bug tracker pdfbox(http://pdfbox.apache.org/), , trying determine decide supported /unsupported image format, , how test format when being used can verify if there issue underlying document format when comparing scans customer documents have attempted extract images from.

i found jbig2 compression format not supported via few tickets submitted via bug tracker (https://issues.apache.org/jira/browse/pdfbox-1439), struggling determine other types of images potentially cause issues.

i checked faqs , documentation , don't see lists regarding information.

any appreciated!
