Graphics with Cairo
Generating graphics on-the-fly in PHP applications is a common requirement. Cairo, from the Freedesktop project, is a fast 2D vector graphics library with outputs to many different devices. It is already used by many big-name Open Source projects such as GNOME and Mozilla Firefox. The PECL Cairo extension for PHP 5.2 and above provides an easy-to-use interface and to Cairo useful for generating images, SVGs and PDFs. This talk will demonstrate how to use its features in common situations, and compare it with other image libraries such as GD. Major points to be presented:
Overview of the Cairo library
Basics of using PECL/Cairo for drawing images
SVG, PDF and Postscript
Integration with existing PHP frameworks and libraries
