--- Comment #3 from Ken Sharp <ken.sharp at artifex.com> 2010-05-26 14:01:46 UTC ---
This was caused by a poor selection of defaults for the pdfwrite device, in
particular the downsampling of all images to 72 dpi, and has since been
addressed (revision 11164). More information and a patch to resolve the issue
can be found here:

I converted the XPS file to PDF using your command line and the resulting PDF
file looks OK to me, comparable with the original XPS file, and not the
horrible mess that the original defaults resulted in.
