        I've completed an initial investigation and there appears to be something we aren't taking into consideration when applying the image mask. We get the 1/0 to white/black making values but every value in between is coming up black. Pretty sure we can address this just need to do a little more digging.

        I've managed to narrow down the problem to the decoding of the jpeg contained in object 53. The issue appears to be related to the incorrect decoding of the images raster. Further debugging is is needed to figure out how to apply the correct colour model.

        This turns out to be a duplicate of PDF-1306 which is great news as I'm just about to close PDF-1306 as well.
