imagecreatefromxbm exists but imagexbm doesn't

[ppowell]

<?php

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

?>

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

imagexbm is only PHP 5.

[man]imagexbm[/man]

I should have just paid attention to that and that would've answered my question.

However, the problem lies in that while I found a way to create XBM thumbnails using ImageMagick's mogrify function, I don't have a workable alternative to zooming in on an XBM nor resizing an XBM, since imagexbm() is not available before PHP 5+ and not sure exactly how to use mogrify in either context.

Ideas?

Upgrade to PHP 5?

That is beyond not an option for a portable web application tool that is required to work in multiple platforms that run PHP 4.1.2 minimum, sorry.
