            Description

            The Image in question is a CCITTFax image. I'll have to create a but for this as it looks like we aren't correctly handling the decode param notation as it isn't a standard form. Would have to do little more testing but from the dictionary entry I suspect the K value isn't being correctly parsed and the columns value for that matter.

              I have the same problem.
              I have a PDF with 2 pages as (scanned) image, i suppose.

              When opening the pdf with icePDF viewer, i only see black pages.

              Is there any progression on this issue?

              I've retested this issue with 4.1.0 and can't seem to reproduce the original problem. I ran ICEpdf 4.1.0 with JAI installed and the image showed up correctly.

              The K value is getting properly handled but the image still isn't loading. When an image can't be loaded we usually fail to black which is likely not the best thing to do. Some more work needs to be done to see if we can't fix this in the next major release.

              I've added a sample file to the support page, sample has private data so we can't post is publicly.
