ImageMagick TM, version 5.1.1, is a robust collection of tools and libraries to read, write, and manipulate an image in any of the more popular image formats including GIF, JPEG, PNG, PDF, and Photo CD. With ImageMagick you can create GIFs 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.
Here are just a few examples of what ImageMagick can do:
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, combine, 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 processing methods directly from your favorite application development environment: Perl, C++, C, or Java.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
