creating gif without windows??? [message #28935]

I want to create a gif or tiff or jpg image where I use plot (line
plotting) and xyout (text) from command line mode and not gui mode. I
want to do this from a cron job on a unix system.

Anybody know how?

The trivial version might have idl plot into a postscript file, then
run the moral equivalent of

gs -sDEVICE=jpeggray -r200 -sOutputFile=test.jpg idl.ps

(the available devices can be found by typing "devicenames ==" into
gs)

Wouldn't it be simpler to use the Z-buffer within IDL? We use that for cron
jobs which produce GIF or JPEG images.
