no surprise here. this is because the output of ps is not a bitmap
but rendered from real postscript graphics elements (and thus it
scales with the resolution). you have to view this similar to other
renderer file formats like povray or tachyon, only that the elements
used are rather crude (this part of the code could use some serious
overhault from a postscript expert, having scalable printable graphics
that look good and don't require a lot of diskspace would be nice).

well, i would call this first and foremost a problem of the
respective software packages and the fact that they don't
provide sufficient backward compatibility for a format that
is supposed to be native to the platform.

you could consider installing some other graphics package
that can read the format and write to supported format,
e.g. Gimp ( ) or ImageMagick
( ). as far as i know, both
packages exist for windows (i don't use windows) and
should be useful beyond your current problem, as they
offer a _lot_ of functionality for image manipulation
at an extremely competitive price (they are free ;-)).
