The font error is related related to an premature assert in the font library. The font renders correctly when adjusted (The 'I' character that starts the first content sentence).
The other issue is related to PDF-276 which is the JDK 1.5/1.6 changes in how JPEG colours are handled. I spend quite a bit of time looking at the the headers of the image and and seem to find anything to dictate when to treat the image as rgba or bgra. Likely have ot take a closer look at Commons Sanselan library to see if it can help, it would also be good in that it would help remove our com.sun dependencies.
For the time being the easiest work around is to use JDK 1.5.
It looks like the fix for PDF-276 has worked out for most users. Closing.
Note from the customer:
I believe the issue is related to the fact that the images in the PDF are in the DeviceCMYK colorspace. I converted the document to sRGB, and this fixes the incorrect colors in the IcePDF rendered output, but has the negative side effect of degrading the quality of the images/colors. So although this hints at the problem, I don't think that converting the documents to RGB is a suitable workaround for us.
Are there any options in the IcePDF API that might allow for working around this issue? I am calling document.getPageImage(...) to render the page, and then using ImageIO.write(image, "png", outStream), to write the image as a png.
