I am running a modified version of the dpsexec Display Postscript
program that comes with IBM Rs/6000s . The modified version
of this postscript interpreter uses an X pixmap instead of an
X window as its context, then dumps the pixmap in XWD format.
This pixmap is 1860x2360 pixels in size . What I do is translate
and scale postscript images to fit inside this larger context.
The reason for doing this is to get a higher resolution XWD file
to print to a color non-postscript printer.
This all works fine except for images which use the 'image' and
'colorimage' operators . It seems that these operators don't produce
any marks on the page past a certain x pixel value (approx x = 1200).
With postscript images with a combination of bitmaps,text and lines
the lines and text appear fine , but any portion of the bitmap
that has an x value > 1200 is not shown. I wonder is this
a Display Postscript feature and if so is there any way around it.
