Hi, I'm new here and I'm new to PHP..

I have a error: Call to undefined function imagettfbbox

this is a dynamic signature PHP script. I've tested my server host website with secure image and here is the result:

This script will test your PHP installation to see if Securimage will run on your server.

GD Support: Yes!
GD Version: bundled (2.0.34 compatible)
TTF Support (FreeType): No
No FreeType support. Cannot use TTF fonts, but you can use GD fonts
JPEG Support: Yes!
PNG Support: Yes!
GIF Read Support: Yes!
GIF Create Support: Yes!

since TTF FreeType is not installed and I cannot use TTF fonts but GD Fonts can be...

How do I change the script to work with GD fonts?

here's the PHP script

Please post the bootstrap script (in other words: the script where those functions are called).
