(PHP 3, PHP 4, PHP 5)imageloadfont -- Load a new font

Description

int imageloadfont (string file)

imageloadfont() loads a user-defined bitmap

font and returns an identifier for the font (that is always

greater than 5, so it will not conflict with the built-in fonts).

It returns FALSE in case of error.

The font file format is currently binary and architecture

dependent. This means you should generate the font files on the

same type of CPU as the machine you are running PHP on.
