            Description

            The file in question displays but the attached ICC_colorspace is not correctly applied. As a result the image comes out pink instead of blue. I tried a few simple test to try an apply the ICC colour space but the ran up against some rendering exceptions. I also tried to apply the alternative CYMK colour space but the image came out more green then blue.

            Further work needs to be done to see why the ICC colour profile can't be applied.

              ICEsoft Public SVN Repository #23192 Wed Nov 24 07:55:23 MST 2010 patrick.corless PDF-221 jpeg2000 logic to better handle ICCBased color spaces. Also tweaked to Stream method alterRasterCMYK2BGRA to get slightly "better" cmyk colour conversion which effect all cmyk image types.

              Updated the colour space handling for ICC colour profiles to use alternative colour space when available. Also updated the stream class to use a different algorithm for calculating rgb colours from cmyk.

              The client should make sure that JAI 1.1.3 or higher is installed on the class path. The jai_imageio.jar is needed to view JPEG2000 images.
