[GRASSLIST:4463] [Fwd: Re: how to generate high resolution image?]

[William W. Hargrove]

It can be helpful to increase the resolution in whatever ps.map device file
you are using.  Otherwise, I think it throws away resolution that can't be
seen on the "paper page".

Makes the files a lot bigger, of course.

Miserable powerpoint may shred your map anyway, though ...  :-0
