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

Table of Contents Example usage scenarios: Features: Limitations ToDo:

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
