Dynamic Heading Generator
By Stewart Rosenberger
http://www.stewartspeak.com/headings/
This script generates PNG images of text, written in
the font/size that you specify. These PNG images are passed
back to the browser. Optionally, they can be cached for later use.
If a cached image is found, a new image will not be generated,
and the existing copy will be sent to the browser.
Additional documentation on PHP's image handling capabilities can
be found at http://www.php.net/image/

**There appears to be a bug with Opentype fonts not rendering special characters properly, but I don't know if the problem is with the script, GD or freetype.

An entry would look like %%{{font text="Text" font="TimesNewRoman" size="24" color="000000" background="ffffff"}}%%
It can render .ttf (Truetype) and .otf (Opentype) font files, but assumes .otf
On an offnote - this is the first time I have done any PHP scripting, so if there are better ways of doing this, please let me know (it took me 2 hours figuring out how to pass stuff between the scripts :D ).
- Testing.
- Hook it into WikiEdit to get custom fontmenus.
font - The font to use (assuming .otf - shouldfix)
size - Fontsize in points
color - Font color without #
background - Background color without #
The script looks for fontrenderer.php in the /fonts/ directory.
//defaults
$text= 'Text' ;
$font= 'defaultfont' ;
$size= 24 ;
$color = '000000' ;
$background = 'ffffff' ;
if ($param == 'size') {$size=$this->htmlspecialchars_ent($vars['size']);}
if ($param == 'color') {$color=$this->htmlspecialchars_ent($vars['color']);}
if ($param == 'background') {$background=$this->htmlspecialchars_ent($vars['background']);}
$output = "<img src=\"/fonts/fontrenderer.php?text=".$text."&font=".$font."&size=".$size."&color=".$color."&background=".$background."\" alt=\"".$text."\" title=\"".$text."\" />";
$font_file = "path/to/fonts/".$_GET['font'].".otf" ;
$font_size = $_GET['size'] ;
$font_color = $_GET['color'] ;
$background_color = $_GET['background'] ;
$cache_folder = 'path/to/cache' ;
?>%%

Deletions:
It is still very rough, but it works.
It accepts .ttf (Truetype) and .otf (Opentype) font files.
- pass font/fontsize/colors/transparency directly to the rendering script (at the moment you need a script for each font/size/color variation).
font - The font to use
$output = "<img src=\"/fonts/".$font.".php?text=".$text."\" alt=\"".$text."\" title=\"".$text."\" />";
$font_file = '/path/to/font' ;
$font_size = 50 ;
$font_color = '#000000' ;
$background_color = '#ffffff' ;
$cache_folder = '/path/to/cache' ;
