Re: Postscript and color map

[Philipp K. J. <ja...@ie...>]

Ok, that's a good thought: to define a bunch of
user-defined line styles, and let the Postscript
terminal use them. (I was stuck on finding a way
to specify the image color map, the way you can
do with GIF, so that I did not even think of this
possibility.)

(Supplying a Postscript prolog requires me to 
understand more Postscript than I want to know.)

I saw the discussion regarding this patch set a
while back on the mailing list, but must admit
that I have not checked it out myself. It's one of
those things where the defaults are almost always
good enough, so the urgency is not high.

On the other hand, I think that a unification of the
entire style/type distinction would be highly welcome.

Best,

		Ph.
