            Description

            The forum user posted a a file that appeared to have an image loading issue. Further investigation showed that the image was in fact being drawn but an large white rectangle was being drawn over top of it. A little more debugging and specification reading indicated that the Separation colour space can specify a None colourant.

            In the following postscript the image is drawn with the 'do' and then a rectangle is defined and filled.

            /Im0 Do Q Q /CS1 cs 0 scn 147.47 439.899 413.001 260.56 re f

            The /CS1 colour space is defined as 36 0 obj[/Separation/None 34 0 R 37 0 R] with the keyword none. The current Separation colour space code ignores the 'None" and will return the the colour white in this case which obfuscates the image.
