decaptcha - PHP CAPTCHA image decoder

This is a CAPTCHA decoder written in PHP for bypassing CAPTCHA SPAM protection features. This is a little unique in that the script generates the character pixel maps automatically from a list of supplied fonts and a character set. The decoder extracts characters from the CAPTCHA image and searches the pixel maps for a match.

The decoder only works with the scode CAPTCHA encoding method! scode is a fairly simple CAPTCHA method therefore it's easy to extract characters. However even with code it was a tedious mission. The nature of this script will hopefully allow for more methods in the future without the tedious manual mapping of characters.
