Yes. In the tool mentionned by Edi, you give the x,y, font, font size for
the new number on the command line.

The next thing to do would be to parse the content of the content-streams to
modify them. But even simple text can be ouput in separated commands (one
for each letter or letter group). And then there is the encoding etc.

No, when people send me some new functionality I credit them in the
file -and- in the contributors file. When I don't forgot to do it that is...
;-) When it's some scattered code then only in the contributors file.
