image processing tools
ImageMagick is an X11 package for display and interactive manipulation
of images.  The package includes tools for image conversion, annotation,
compositing, animation, and creating montages.  ImageMagick can read and
write many of the more popular image formats (e.g. JPEG, TIFF, PNM, XPM,
Photo CD, etc.).

With ImageMagick you can:

     o load an image from a file
     o display the next image
     o display the former image
     o display a sequence of images as a slide show
     o write the image to a file
     o print the image to a Postscript printer
     o delete the image file
     o create a Visual Image Directory
     o select the image to display by its thumbnail rather than name
     o undo last image transformation
     o copy a region of the image
