It takes your PNG's, chews them up and spits out sprites!
point bin/css-spriter at a directory, and watch it sprite away!
CSS-Spriter uses Chunky PNG for it's PNG manipulation. Not only is it super fast, but the library is a great example of fast, efficient ruby programming.
Chunky PNG is written in pure ruby, this means you can sprite up anything using MRI, JRuby, or Rubinius.
sudo gem install css-spriter
If you point the sprite command at a directory tree by default it will construct sprites for each of the sub directories and generate a single css to access all of the sprites which is placed in the root of the directory tree
For a full list of options:
script/plugin install git://github.com/aberant/css-spriter.git
CSS-Spriter assumes all of your sprites are located in the directory public/images/sprites. This directory should contain sub-directories for each sprite you wish to create. The css class names for an image in a sprite will take the form <directory_name>_<image_name>. Here is an example:
sprites / cars / ford.png chevy.png planes / boeing.png cesna.png
Running the sprite:generate task does all the work. Each sprite directory (cars, planes) will now contain a sprite.png. Spittle will also generate a sprites.css stylesheet in public/stylesheets/ that you should include in your layout. If you wished to use the ford image from the cars sprite you would give the 'cars_ford' class to the desired element in the view. That's it!
