That's a piece of cake

That's exactly what I want to do. But I don't want to just overlay some text
or graphics - I want to produce an embossed image on the picture which still
leaves all of the picture visible - think of a paper embosser on a printed
page - you can still read the page/see the image but the embossing is
clearly visible too.

Have done - up, down, and sideways. Been using IM and the pnm tools for
years, and what kills me is that I'm sure I read how to do this once (but I
may be confused with mogrify's -emboss option which does NOT do what I want).

And I'm currently using SuSE 6.4 - there doesn't seem to be as much IM
documentation as I used to have. A visit to the web site is probably in order.



Regards,


Niall
