I used your program with 250 colors. I don't see
anything like that. :-)
You might try configuring your PostScript file with
PSConfig. That usually solves *most* PostScript problems. :-)
IF KEYWORD_SET(ps) THEN BEGIN
rightsize = PSWINDOW(/CM)
this_device = !D.name
keywords = PSConfig(filename='toto.ps', _Extra=rightsize)
SET_PLOT,'PS'
device, _EXTRA=keywords
ENDIF
Is this a problem with your viewer? Have you actually
printed the PostScript file?
I don't know. It looks perfectly fine to me.
Cheers,
David
