            Description

            The attached forum PDF has a jbig2 image that isn't being correctly decoded. PdfCompressor is being used on the file and doing something to the image streams which is causing problems with ICEpdf's imaging core.

              I assumed that there was something wrong with the jbig2 handler but after substituting our code with another I got the same result. I dug a little deeper an it turned out the issue was related to masking which turned into 4 days of refactoring our image handling code.

              The end result is that we can no display the PDF correctly as well other PDF encoded similarly using LuraDocument PDF Compressor. One more note is that I also added optional content support for xform objects.

              ICEsoft Public SVN Repository #32642 Thu Dec 06 13:14:44 MST 2012 patrick.corless PDF-387 major rework of how we apply image masks and smaks to images. An attempt was made to normalize the process instead of applying special cases to each image format type.

              The PDF attached to support case render fine but the PDF sample attached to the form is still problematic. I will have to investigate updating our jbig2 library.

              Pushing out to a major release as switching to a new release will need to happen on a major release.
