ErlyCairo allows generation of PNG images via 2D vector drawing.

Example usage scenarios:

• server side creation of HTML / CSS background images such as gradients, rounded corners, etc.
• dynamic creation of CAPTCHA images

Features:

• OTP server for starting, accessing and stopping the C-node
• bindings for a subset of the cairo 2D graphics functions
• simple demo application
• C source compiles on mac and Ubuntu Linux (cairo library must be installed)

Limitations

• PNG images only. Just for CSS / HTML background images, this is usually enough, if used in conjunction with a hack like http://24ways.org/2007/supersleight-transparent-png-in-ie6. If you need other image formats, take a look at http://code.google.com/p/erlmagic/

ToDo:

• binding ALL cairo functions
• Cairo version compatibility check
• documentation, wiki, more examples
