1. ImageMagick is a powerful image display, conversion and manipulation tool. It runs in an X session. With this tool, you can view, edit and display a varietyof image formats. From Mandrake 9.0 RPM

2. Image manipulation programs. Imagemagick is a set of programs to manipulate various image formats (JPEG, TIFF, PhotoCD, PBM, XPM, etc...). All manipulations can be achieved through shell commands as well as through a X11 graphical interface (display). Possible effects: colormap manipulation, channel operations, thumbnail creation, image annotation, limited drawing, image distortion, etc... This package suggests a postscript interpreter (gs) to read postscript files. It will however function happily without it (as long as you don't want to read postscript). From Debian 3.0r0 APT
