GradientServer

A simple image server that will render vertical gradient images suitable for use as backgrounds.

Requires:

• Rails 2.3
• RMagick

Please note this is basically 10 lines of code and I'm just throwing it out there for chuckles.

Install:

./script/plugin install git://github.com/tablatom/gradient_server.git

Then just fetch an image using a URL as follows

/gradient_images/<height>:<start-color>:<end-color>.<format>

Colors are 3 or 6 digit hex values, as in CSS.

e.g. try something like this in your stylesheet

div.featured { background: url(/gradient_images/50:aaa:fff.png) repeat-x white }

You can also do multiple gradients, separated by '::', which are stacked vertically:

div.featured { 
  height: 100px;
  background: url(/gradient_images/50:aaa:fff::50:fff:aaa.png) repeat-x 
}

Uses page-caching. The images will end up in public/gradient_images and will then serve up without hitting any ruby code.
