I found a solution at http://www.webdeveloper.com/forum/showth...p?t=178210.

Nearly at line

514 - $dst_img = $create($this->width, $this->height);

I changed the code this way:

//$dst_img = $create($this->width, $this->height);

/* TRANSPARENT PNG */
$dst_img = imagecreatetruecolor($this->width, $this->height);
$transparent = imagecolorallocatealpha($dst_img,0,255,0,127);
imagefill($dst_img,0,0,$transparent);

$copy($dst_img, $src_img, 0, 0, $this->x_axis, $this->y_axis, $this->width, $this->height, $this->orig_width, $this->orig_height);

imageAlphaBlending($dst_img, false);
imageSaveAlpha($dst_img, true);

..and now it works.

wow, thanx for that fix, it just helped me a lot and prevented further pain. Now I just must remember to fix it again in case of any CI-upgrade
