            Description

            A client sent us a file that was a bit slow to render. After closer inspection there were two main hot spots.

            The first being the application of DeviceCMYK using ICC colour profiles. In this particular case the CMYK converter code had excellent colour match and was a lot faster then using the ICC colour profile.

            The second issue was the use of fairly large image bands that used the calRGB colour space. This particular colour space is decoded by the RawDecoder and is quite slow.
