ImageMagick is available in rpm form as part of the Red Hat Linux distribution or separately from the ImageMagick web site. There are source distributions and binaries for other operating systems also available at the same site. You may require other graphics libraries in order to get ImageMagick to work. In particular, the MPEG library is available at the ImageMagick site.
My Linux system is based around Red Hat 4.2 and I found that I needed to upgrade the libpng library to get ImageMagick to work. You may find that you need to install or upgrade some of your other graphics libraries to use ImageMagick. In order to compile ImageMagick, you need to install the -devel versions of the RPMs as well as the library.
If you want to recompile ImageMagick from source, read the instructions provided carefully. ImageMagick depends on many libraries for support of the individual graphic file formats and the source code for each of these must be obtained and compiled first. Full instructions on how to do this are provided with the ImageMagick distribution.
The official ImageMagick web page is at http://www.wizards.dupont.com/cristy/ImageMagick.html. There is also a mailing list; to subscribe send mail to majordomo@wizards.dupont.com with “subscribe magick” as the body of the message.
It is also possible to compile ImageMagick without the support for X display and capture of images if your platform does not support the X Window System or if only command-line conversion of images is required. The README details how to do this.
