In Detail

The book is packed with interesting and fun examples. We had a lot of fun coming up with cool ways to demonstrate ImageMagick's power, and we're sure you'll have fun learning how to create them.

Although the printed book is in black and white, there is a full colour PDF of the screenshots freely available that includes all of the images in the book.

ImageMagick is a free software suite to create, edit, and compose bitmap images using text-based commands. The commands can be issued from the command line, but more often will be included in web or desktop applications – carrying out complex image-manipulation tasks in response to the user's input.

ImageMagick is a popular way for generating images on-the-fly in web pages, whether it's generating thumbnails from a large image, or creating complex combinations of images, text, and effects chosen by a visitor or the web site's creator.
