or if you are using Unix you could use the
GtkPrintJob/GtkPrintUnixDialog interface to send the postscript file
directly to the underlying print system (cups or lpr) - see
gtk_print_job_set_source_file().
Unfortunately, this needs to work on W32 platform as well, so the
UNIX-specific solution won't work for me.
You can draw the postscript file to the cairo surface in the ordinary
way using GtkPrintOperation,
I'm confused. The example for the draw-page signal renders to the cairo
print context using cairo commands. How do I take a postscript file and
"draw" it to this cairo print context (in the ordinary way)?
I've looked at the GTK+ and Cairo documentation and see only functions
that are uni-directional, i.e., Cairo -> Postscript. Are there functions
that go the other direction, PS -> Cairo?
Or am I missing something completely obvious?
thanks,
richard
