[gentoo-user] watermark PS files

[gentoo-user] watermark PS files

[Joseph]

watermark to existing PS files (ex. for faxing etc.)
Does anybody knows how to do it?
I've run onto various scripts but didn't have much luck with most of
them.
This little postscript snippet prints CONFIDENTIAL diagonally across the
page:
--------example-----------
/wp$y 792 def
/wp$x 612 def
%-------Customize Here-------
/font /Helvetica-Bold def
/pointsize 96 def
/text1 (CONFIDENTIAL) def
%-------End Customization----
/center {dup stringwidth pop
2 div neg 0 rmoveto} def
wp$x 2 div wp$y 2 div pointsize 2 div sub moveto
.85 setgray
font findfont pointsize scalefont setfont
45 rotate
0 0 text1 center ashow
%
--------end example---------

but it needs to be inserted at the right spot or it will not work.

Thanks, sounds like a good solution, though you are right I need to to
recompile gcc with gcj
