README

This minimal library generates identifiers based on an input seed. It can be used to generate avatar images or visualize other identifying info (like crypto keys). The result is a PNG or SVG image.

It has no dependencies except the GD library extension for PHP for PNG images.

Usage

See the demo.html/demo.php files for examples.

You can tune the following parameters:

• The size of the resulting image (via constructor)
• The number of rings to generate (via constructor)
• Multicolor versus monochrome image (via setMono() method)

The monochrome version uses a single color and variates the alpha transparency of the rings.
