            Description

            The attached PDF has some significant colour differences between the output of the PDF viewer and Adobe. The bulk of the text should be black, and is blue and the colours in the bar graph differ between the two viewers.

                I'll have to take a closer look at this one, looks like a colour space issue especially with function 4 errors.

                Appears to be the same type 4 function issue.

                It took a few days but I think the end result is a working type 4 function or PostScript calculator. The PDF in question displays correctly now. I was hoping for better interpolation on some other problem PDF's that had missing type 4 support but in those cases other colour spaces issue are still at large.

                Closing issue, PDF renderings correctly now.
