You spent hours getting RMagick installed. Here’s a chance to learn
how to use it for something besides making thumbnails!
A couple of weeks ago I ran across a tutorial called Web 2.0 Design
Kit[1] that shows how to create so-called Web 2.0 design effects using
Photoshop. I started wondering if it was possible to reproduce these
effects with RMagick. Well, it turns out that yes, it is, so I wrote up
the process as Part 2 of the “Alpha Compositing” tutorial that I started
last February. This part of the tutorial shows how to dynamically create
images with transparency, the “glass” effect, gradients, shadows, and
text.
The tutorial is here: http://rmagick.rubyforge.org/web2/web2.html.
