How to rotate an image in GD Image Library while keeping transparency?

Question

I\'m making a skin previewer for my site; I need to rotate parts of an image to create a representation of this for my users to see.

The skin is a PNG file, and all part

Answer 1

I use that to rotate a PNG and preserve transparency color. Works like a charm. It's "basic GD".

 $rotation = 135;
 $handle_rotated = imagerotate($handle_not_rotated,$rotation,0);
 imagealphablending($handle_rotated, true);
 imagesavealpha($handle_rotated, true); 

Don't know if it's what you're looking for?
