general image manipulation tool
ImageMagick is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats (over 87 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image and save your completed work in the same or differing image format. Image processing operations are available from the command line, as well as through C, C++, Perl, or Java programming interfaces.
Convert an image from one format to another (e.g. TIFF to JPEG) Resize, rotate, sharpen, color reduce, or add special effects to an image Create a montage of image thumbnails Create a transparent image suitable for use on the Web Turn a group of images into a GIF animation sequence Create a composite image by combining several separate images Draw shapes or text on an image Decorate an image with a border or frame Describe the format and characteristics of an image
You can access ImageMagick functions directly from the command line using the ImageMagick tools convert , mogrify , montage , composite , or identify . Use the display program to interactively manipulate your images or animate an image sequence from a graphical panel. Finally you have access to the various image manipulation methods directly from the most popular application development environment: Perl , C++ , C , Python, or Java .

*Tags*: import, snapshot, screen shot, screen capture
import that comes with ImageMagick will capture an application or X server screen.
Example:
import -frame app-snap.jpg import -descend image.png
documented on: 2007.06.19
-antialias
remove pixel aliasing
-blur <radius>x<sigma>
blur the image with a Gaussian operator
-charcoal <factor>
simulate a charcoal drawing
-contrast
enhance or reduce the image contrast
-level <value>
adjust the level of image contrast
-dither
apply Floyd/Steinberg error diffusion to the image
-edge <radius>
detect edges within an image
-emboss
emboss an image
-enhance
apply a digital filter to enhance a noisy image
-equalize
perform histogram equalization to the image
-fuzz <distance>{%}
colors within this distance are considered equal
-gamma <value>
level of gamma correction
-Gaussian <radius>x<sigma>
blur the image with a Gaussian operator

add or reduce noise in an image
-normalize
transform image to span the full range of color values -opaque <color>
change this color to the pen color within the image
-quality <value>
JPEG/MIFF/PNG compression level. Quality is 0 (worst) to 100 (best). The
default is 75.
-raise <width>x<height>
lighten or darken image edges
-roll {+-}<x>{+-}<y>
roll an image vertically or horizontally
-rotate <degrees>{<}{>}

ImageMagick ™, version 3.8.6, is a package for display and interactive manipulation of images for the X Window System. ImageMagick performs, also as command line programs, among others 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 supports also the Drag-and-Drop protocol form the OffiX package and many of the more popular image formats including JPEG, MPEG, PNG, TIFF, Photo CD, etc.
