Hello,

I want to thank you deeply for having written this class.

I would like to save the PNG with an alhpa channel and full transparency....normally this is referred to as a PNG-24....is there an easy answer? or should I go study the gd documentation?

Again many thanks and my deepest respects.
Jhave

use this function to save alpha channel..

imagesavealpha($image, true);
ImageAlphaBlending($image, false);

For GD 2.0.1 or later...

Hope u will find it useful.

Regards..
