<?php
/*
  This quick script converts the character font array in the defaultFont.php
  to a data array that is used by the cellCaptcha class to create the characters
  use captcha output.

    Look at the defaultFont.php if you want to modify the display characters
  to your own liking or use it as an example to build your own font.

  1.  Just be sure when you run this script to require/include your character
  font array like below where it says require('defaultFont.php').

  2. Then when running the convert function, pass in the name of your character
  font array like the one in the defaultFont.php.

  3. Copy browser output of this script to replace the content of
     fontmatrix.php that provides the array data that the cellCaptcha
     class uses to build the captcha output.
