RMagick Download Page

RMagick is an interface between the Ruby programming language and the ImageMagick® and GraphicsMagick image processing libraries.

Thumbnails are just the start! Check out the RMagick portfolio. The first page shows some basic transformations. Page 2 demonstrates special effects. Page 3 illustrates the drawing API.

RMagick comes with comprehensive documentation in HTML format. The documenation for your version of RMagick is installed on your system along with the RMagick software. If you are using RMagick on another system such as a web hosting service you can read the documenation online at one of these locations.

Note: The online documenation may not be for the most recent version of RMagick. The online documentation may be for a different version of RMagick than you are using.

You can use RMagick on Linux, FreeBSD, OS X and other *nix-like systems such as Solaris and Cygwin. You can also use RMagick on Windows XP and Vista. RMagick works with Ruby 1.8. If you do not have Ruby, you can get it from www.ruby-lang.org. You must have ImageMagick 6.0.0 or later, or GraphicsMagick 1.0 or later. (I recommend ImageMagick 6.3.0 or later, or GraphicsMagick 1.1.) You only need one of ImageMagick or GraphicsMagick. RMagick works equally well with either. See below for links to the ImageMagick and GraphicsMagick download sites.

Look here for short, in-depth articles about RMagick. New ones will be added from time-to-time.

These fine books include information about using RMagick. Find them at your favorite bookstore.
