#43508 [Opn->Bgs]: ImageCreateFromPNG does not set transparent color

ID: 43508 Updated by: pajoye@php.net Reported By: vbhunt at silverfox dot com -Status: Open +Status: Bogus Bug Type: GD related Operating System: Windows XP Professional Ver 2SP2 PHP Version: 5.2.5 Assigned To: pajoye New Comment: There is no transparent color (or known as background color). The alert.png for example uses the alpha channel, and the borders of the images is filled with the white color and 100% alpha. A png image can use either the alpha channel or the transparent color but not both.
