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:

$magick> svn co \
https://www.imagemagick.org/subversion/ImageMagick/branches/ImageMagick-6.6.0 \
ImageMagick-6.6.0

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

$magick> svn co https://www.imagemagick.org/subversion/ImageMagick/trunk ImageMagick

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

$magick> svn update

and only the files which have changed are updated.
