Re: Don't understand PS <-> gnomeprint - More

[John Coppens <john jcoppens com>]

Me again - no solution yet, more strangeness:

Please correct me if I'm wrong - I've seen a remark somewhere 'To get a
Postscript manual to understand gnome-print use', so I'm following this
advice.

In a loop, I generate a lot of labels, repeating the following code:

  print_setrgbcolor(prt_last_font_color);
			( generates a gnome_print_setrgbcolor )
  gnome_print_gsave(gpc);
  gnome_print_translate(gpc, chrad * x, chrad * (y + 1));
  gnome_print_rotate(gpc, angle * 180 / M_PI);
  gnome_print_moveto(gpc, size/8, size/8);
  gnome_print_show(gpc, str);
  gnome_print_grestore(gpc);


The generated PS code is:

q					<-- extra gsave, so my
					gnome_print_gsave isn't
					really necessary?
