Re: Loading postscript file

[Dov Grobgeld <dov grobgeld gmail com>]

As far as I know (but perhaps someone else knows better) the only freely
available postscript interpreter is ghostscript (which is used by gv).
Ghostscript is distributed under the GPL license which prevents Gtk, which
is distributed under the LGPL, to depend on it. The easiest way round this
is simply to run system() ghostscript as a subprocess and have it output a
raster file, e.g. in the pnm format, and then load this file into your gtk
program.

Here is the command line I've been using for this in the past:

gs -q -dNOPAUSE -g100x200 -r75x75 -sDEVICE=ppmraw -sOutputFile=foo.pgm
trans.ps myfile.ps quit.ps

where trans.ps encodes of the shift and rotation of the file myfile.ps

Hope this helps.

Regards,
Dov
