Speaking of which, I ran into an interesting PostScript
problem yesterday that I had forgotten I knew anything
about! :-)
I test the code in my book by pasting it to the IDL
command line. When it works the way it is suppose to
I call PS_Start, paste the code, call PS_End with the PNG
keyword set, and bam! I have a perfect PNG file to import
into the book file. Extremely easy and I make sure the
book is free of code typos, too.
So, I was working on the Surface Plot chapter yesterday,
and all was going normally (you know, SLOWLY), when I
decided that one of the surface plots I came up with
was so nice that I should make it a candidate for the
cover of the book. So I wanted to make it a larger
size.
Rather than use PS_Start, I just thought I would configure
the PostScript device myself with PSConfig. So I did and
ran my programs and the surface labels weren't rotated. :-(
I made sure !P.FONT=0 and ran it again. Still not rotated. :-( :-(
Eventually, I had to look at PS_Start to see what the heck it
was doing! Setting !P.Font to 1, of course, because only
Hershey and True-Type fonts can be rotated in PostScript in
this 3D way. Wow. I've been using PS_Start for so long I
forgot all about that.
No wonder people who don't use my software run around
with confused looks all the time. :-)
Cheers,
David
