The ImageMagick stable and development source releases are available from Subversion. This a convenient way for developers to download the ImageMagick source, fix bugs, or add new features.

To retrieve, or check out ImageMagick stable, use this command:

 svn co https://subversion.imagemagick.org/subversion/ImageMagick/branches/ImageMagick-6.9.1 ImageMagick-6.9.1

To retrieve, or check out ImageMagick development, use this command:

svn co https://subversion.imagemagick.org/subversion/ImageMagick/trunk ImageMagick

To update the sources within a previously checked out directory, execute:

svn update

and only the files which have changed are updated.
