I’ve just uploaded the latest in my series of articles about using  
RMagick. This one explains a very simple technique for creating a  
digital watermark that looks like embossed text. I hope you find it  
useful.

The RMagick home page has links to the entire series:

RMagick is an interface to the ImageMagick ([http://www.imagemagick.org](http://www.imagemagick.org))  
and GraphicsMagick ([http://www.graphicsmagick.org](http://www.graphicsmagick.org)) image processing  
libraries that supports more than 90 image formats, including GIF, JPEG,  
and PNG. RMagick includes RVG, a 2D drawing API. Comprehensive HTML  
documentation for RMagick is available here:  
[RMagick 1.15.0 User's Guide and Reference](http://www.simplesystems.org/RMagick/doc/index.html) and here:
