Can't Get Transparent Png's With Ephpthumb Extension

Has anyone tried EPhpThumb extension?

Simple enough


 * @var $app CWebApplication

 * @var $phpThumb EPhpThumb


$app = Yii::app();

$phpThumb = $app->phpThumb;


outputs ruined PNG image with black background, no transparency at all. Not to even mention resizing.

I was digging through its source code and see clearly, that by default, it is has transparency enabled and it should work, but it does not.


To the right is starting image with nice transparency and fade effect, to the left is output result from code above.

Please, suggest me solution, other than writing my own GD image post-processing class for resizing and display.
