Why does this transparent PNG cause borders when combined using GD?

Question

I am trying to create an image from an another image using PHP. Here is my code:

Answer 1

Can you try to enable alpha blending on $image before you copy the original to it:

imagealphablending($image, true); 

Second try would be to create a transparent color and to fill $image with that color before the copy.

$transparent = imagecolorallocatealpha($image, 0, 0, 0, 127);
imagefill($image, 0, 0, $transparent);
imagealphablending($image, true);
