The IBM developerWorks site has a new tutorial posted (registration/login required) talking about image creating in PHP using the GD library.

The purpose of this tutorial is to show you how to get started with the GD library and to provide a variety of techniques you can apply to your Web-page coding. The tutorial doesn't cover every GD function, but it teaches you the basics. The Resources section provides Web sites where you can learn more about using the GD library.

They go through the creation of sample images, working with gradients and lines, adding text, saving the image data out to a file and how to work with existing graphics to modify them.

Kore Nordmann has posted a new article series (to the "Articles" section of his site) with six different pieces talking about different aspects of image creation with PHP:

• Image creation with PHP - Image Tools
• Image creation with PHP - Text rendering
• Image creation with PHP - Integrating bitmaps
• Image creation with PHP - Gradient rendering
• Image creation with PHP - A first shape
• Image creation with PHP - Formats & Libraries

Each of them can be read separately, but they're all part of a series and make more sense when read together.

On Ozh's site, FrenchFragFactory.net, today, there's this handy little post dealing with the creation of gradients in PHP with the help of GD.

Here is a small PHP function I wrote that emulates a gradient fill of an image.

Disclaimer : there are probably existing alternatives or classes, maybe in PEAR. I didn't check. I wanted to write a function myself, as part of my GD training grounds.

The script is simple enough, and only uses four different variable values to make the patterns. There are a few examples of the end result in the form of a basic square output, but (as he mentions) it can be used just as easily in other situations. The source code is availible in either plain-text or in a .phps style file.
