psidtopgm

[ALOBO]

Hi!, this is not strictly grass but...
I'm trying to convert a PostScript into something that I could to my word
processor, a PICT or TIFF file for example. Using psidtopgm from
the Jef Poskanzer's routines seems the most obvious way, but the way to
do it is not clear at all:

""To use it you have to manually extract the readhexstring data portion from your PostScript file, and then
give the width, height, and bits/sample on the command line.
Before you attempt this, you should
at least
read the description of the "image" operator in the PostScript Language
Reference Manual."""

Well, I don't have the manual and have no idea of what the readhexstring data portion is. Hewre is the beginning of my ps file. Anybody out there knows
what to delete and where can I get the width, height, and bits/sample?

Thanks
