            Description

            The document in question does not correctly decode and does so without error. When I force the JAI decode logic the images does load. Unfortunately I'm not an expert with the CCITTFax specification so I'm left scratching my head a bit.

            I'm thinking about creating an force JAI system property for CCITTFax images as work around for the client. Alternatively I'm going to have to spend quite a bit of time for this one off document learning the specification and debugging the code.

              Marking on as closed until further feedback from client. The use of org.icepdf.core.ccittfax.jai=true can significantly speed up the rendering of the this PDF.

              I've added the org.icepdf.core.ccittfax.jai system property as a work around hopefully more time can be spent finding out why the original ccittfax algorithm is failing.
