ABSTRACT

Making dynamic graphics is extremely easy. Since PHP is limited
neither to dealing with regular numbers and strings nor to generating
regular HTML output, developers can analyse, create and manipulate
images, store them in files using wide range of image formats, send
images directly to a browser, and so on.

PHP 5 - due to its new object model - makes it even easier. OO
programming style and some design patterns let to achieve better
performance. Nothing should be done from scratch - just reuse existing
libraries and packages.

This rich illustrated ebook provides detailed description and
explanation of PHP extensions and PEAR packages related to processing
images on the fly. It contains lots of modern well commented code
samples as well as several complete practical examples. There are
solutions for many common tasks such as getting image information,
drawing graphics primitives, centering text, making thumbnails,
counters, watermarks, charts, captchas, converting image formats, etc.
