imagecreatefromxbm exists but imagexbm doesn't

[comp.lang.php]

[PHP]
<?php

echo function_exists('imagecreatefromxbm'); // PRODUCES 1
echo function_exists('imagexbm'); // PRODUCES.. WELL.. NULL

?>
[/PHP]

Use: PHP 4.3.9 with bundled GD 2.0.1

Why would one function exist while the other not exist? Is this perhaps
due to XBM (X-Bitmap) images being "read-only", or is it something
else?

Thanx
Phil

"imagexbm (PHP 5)"

You're on PHP4, XBM generation appears to be specific to the bundled GD
library (core GD doesn't appear to support it, at least there's no imagexbm
function in the main API; PHP has a slightly modified version compared with the
official GD library), and so it seems it was added in a later version to the
one you have.

I see. Ok what workarounds do you recommend then for performing a zoom
and resizing an XBM Bitmap?
