ImageMagick, version 3.6.5, is a package for display and interactive manipulation of images for the X Window System. It is written in C and interfaces to the X library, and therefore does not require any proprietary toolkit in order to compile. Although the software is copyrighted, it is available for free and can be redistributed without fee.
The ImageMagick image display tool first determines the hardware capabilities of your workstation. If the number of unique colors in an image is less than or equal to the number the workstation can support, the image is displayed in an X window. Otherwise, the number of colors in the image is first reduced to match the color resolution of the workstation before it is displayed.
In addition to the image display program, ImageMagick also has command line programs that perform these functions:
Describe the format and characteristics of an image
Convert an image from one format to another
Transform an image or sequence of images
Read an image from an X server and output it as an image file
Animate a sequence of images
Combine one or more images to create new images
Create a composite image by combining several separate images
Segment an image based on the color histogram
Retrieve, list, or print files from a remote network site
ImageMagick is known to compile and run on virtually any Unix system including Linux. It also runs under VMS. See README for compiling instructions.
Added -raise to lighten/darken image edges to create a 3-D effect.
Access a range of frames from an MPEG files, for example, video.mpg[50-75].

ImageMagick can now read and write
JBIG , PDF,
and PNG image files.
Added -frame to ImageMagick utilities to surround an image with
an ornamental border.
Added -opaque to ImageMagick utilities to change the color
