Compass Magick

Dynamic image generation for Compass using ChunkyPNG/PhantomJS (no dependency on RMagick).

body {
  background: transparent magick-canvas(100px, 100px,
    magick-fill(magick-linear-gradient(red, green, blue))
  ) repeat-x;
}

A CSS3 Sassy Button recreated in Compass Magick:
StanAngeloff.github.com/compass-magick/ (showcases all features)

Installation is simple via RubyGems. Compass and ChunkyPNG are required.

gem install compass-magick

If you wish to use PhantomJS, please follow the build instructions.

To start a new Compass project with Magick included:

compass create -r magick my_project

To use Compass Magick within your existing projects, require the plugin from your Compass configuration:

require 'magick'

There is a short tutorial available which should guide you through creating a simple themeable button.

List of all available commands.

RDoc is also available for the entire project.

compass-canvas is a Compass plugin that provides a drawing surface similar to the <canvas> element in JavaScript and Turtle graphics in other programming languages. It uses Cairo as a back-end to perform all graphics operations. The project supports anti-aliasing, vector graphics, gradients, masks, clipping, complex operations like drop shadow and many more.

Compass Magick is very much a work in progress. Documentation is sparse, speed is a major issue and there are probably a lot of bugs.

You can help by looking at any of the following areas (ordered by priority):

• Optimizing the code as floating point math may not always be needed and too many object copies sucks
• Writing tests to make sure nothing breaks in new versions
• Performing code reviews since this is my very first Ruby project and I don't have any experience with the language so there are probably many stOOpid things in code
• Improving RDoc because you can never have too much documentation
• Adding new plugins. Compass Magick looks for Ruby files and imports those on startup
• Submitting more examples to show off what Compass Magick can do
• Opening issues for features you find missing or broken
• Porting over some of CamanJS' goodness, we all love visual effects

• Willem van Bergen for his great work on ChunkyPNG which has been a major source of knowledge while working on the project
• Chris Eppstein for Compass itself
• The Ruby community for being awesome and welcoming a stranger
