Riassunto

Unleash the power of ImageMagick with this fast, friendly guide. It's packed with examples of photo manipulations, logo creation, animations, and complete web projects. With this book up your sleeve, you'll be creating spellbinding images from code in no time. 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. Sohail Salehi is an experienced computer graphics artist, working with 2D, 3D, and video graphics. The book shows his techniques in action. This is no laborious walk through of ImageMagick, with one dull example after another. The chapters consist of workshops, each one applying a set of ImageMagick commands to produce surprising and exciting results. As you read the book, you will learn the features of ImageMagick as well as getting lots of inspiration and ideas for how you can use it in your own projects. You'll be amazed by the creative results you can achieve using code.
