Package: ghostscript
Version: 8.70~dfsg-2
Severity: wishlist
A PDF file consisting of a 300 DPI page-size image, generated by
printing from Open Office Draw to the CUPS PDF converter, is poorly
rendered by both Evince and the GIMP, so I'm making a guess that the
problem lies in Ghostscript. It seems to be downsampling images by
skipping pixels rather than averaging them. I've attached snippets of
the image (a) at its original 300 DPI, (b) scaled poorly to 100 DPI by
Ghostscript, and (c) scaled well to 100 DPI by the GIMP.
