Steve--
I'm not sure what you have against screen-dumping the display.
We've generated some really slick overheads with both of the
following:
If you're running Sun Open Windows, the snapshot utility lets
you capture displays as sun raster files. You can manipulate
colors, etc. in these files with xview. Then use Jeff
Poskanzer's public-domain portable bitmap tools to convert
these through a portable bitmap format to postscript, e.g.:
rasttopnm sunrast.rs | pnmtops | lpr -q yourprinter
Use pnmrotate 90 if you want landscape rather than portrait.
If you're running an X-emulator such as Exceed or Reflection
on a micro under MS Windows, you can clip images right into whatever
else--Adobe Photoshop, Powerpoint, your documents....
Or use the CELL monitor, as Sue Huse suggests. Just size it
appropriately. Malcolm Williamson at CAST put out some detailed
postings on using CELL last year; they're in the grassu archives.

Is there a way to print the current display to a PostScript file? Can
the display be saved to a raster file? I have successfully printed
out my raster files using ps.map and would now like create PostScript
files of graphics generated from commands such as d.histogram and d.3d.
Is this possible? I am not interested in sceendumping the display!
Thanks again,
Steve King
Greetings,
Thanks to all who replied to my ps.map question. Everything seems to work.
I was following a discussion in the archives regarding viewing files
created by ps.map with the Ghostview application and am wondering why I
can't. The following error is generated:
Unexpected interpreter error -12!
Error object: (270)file 0x4009a488
Execution stack at 0x40009ce8:
..9ce8: 0x0c oper ------e--- 0x0009 0x40008a02 = %interp_exit
Finally, some have commented on the utility of PS as opposed to a simple
screen dump and the answer (as I understand it) is that PS allows the
resolution of the original image to be printed (subject to the resolution
of the printer) where as a screendump limits the graphic to the resolution
of the screen. Note that what the screen displays is often only a
sampling of the true image depending on your monitor. A simple raster
image may print nicely after being bitmapped (i.e., screendumped) but a
more complex graphic (i.e., an image classified from satellite imagery
will look better if a PS file is produced. Output created from d.3d will
also look quite a bit nicer when ps.mapped as should text and lines in an
image.
