[Tuxpaint-devel] Tux Paint PostScript printing code rewritten

[Bill K. <nb...@so...>]

The PostScript generating code in Tux Paint has been moved to an external
set of source files (postscript_print.c and .h) and the PS content itself
has been rewritten from the ground up (based on NetPBM's "pnmtops" source
code, and examining its output).

It's not perfect, but it should be a lot better.

Bonus: Tux Paint targets that use this PostScript generating code
(that is, _not_ Windows, Mac OS X or BeOS, which have their own
platform-specific print code) now uses "libprint" to determine the
user's or system's current default paper size (e.g., "letter" or "a4").

That size (in PS points) is included in the generated PostScript, and
Tux Paint asks the PS device to scale the user's picture up to fit
on the page.  It rotates it appropriately, based on paper size and
image aspect ratio.

Finally, Tux Paint lets the user specify a different paper size than
what "libprint" discovers (via $PAPER or /etc/papersize).  A pulldown
that shows all paper sizes known by "libprint" has been added to
Tux Paint Config.

PLEASE TEST! :^)  Recommendations to make it perfect would be appreciated.
(Look for "FIXME" comments in the postscript_print.c :^) )

Thanks!  (Special thanks to my friend Henry House for looking over the
current PS output for me, and giving recommendations.  And thanks to
Jef Poskanzer, who wrote "pnmtops" back in the day.)
