Create thumbnail on canvas?

[eluser]ChristiaanT[/eluser]
Hello,

I am wondering if it's possible to create a thumbnail on a blank fixed-sized canvas. I need this to get a perfect image with vertical centering too. So for example I want a thumbnail that has a fixed width and height of 200 x 200px. I wan't to create that blank canvas using GD and then 'place' an image in the center/center of that canvas. Is this possible using the image_lib? I looked around, but can't find a solution here in this forums. Now I hope you can help me.

Thanks for your help.
