#41666 [Opn->Fbk]: imageTTFtext without Alpha

ID: 41666 Updated by: pajoye@php.net Reported By: cyberline at techno4ever dot net -Status: Open +Status: Feedback Bug Type: GD related Operating System: Debian 3.1 PHP Version: 5.2.3 Assigned To: pajoye New Comment: Ok, I understand what you mean now. There is two things. Per default gd does not save the alpha information, you have to enable this mode using: imagesavealpha($image, true); The second problem is the blending mode while copying/resizing the embed image. You have to disable the blending operation. Try: <?php $image = imagecreatetruecolor(222, 189); $embed = imagecreatefrompng($logofile); $white = imagecolorallocate($image, 255, 255, 255); imagealphablending($image, 0); imagecopyresized($image, $embed, 0, 0, 0, 0, 222, 189, imagesx($embed), imagesy($embed)); imagettftext($image, 12, 0, 5, 15, $white, $font, $text); imagesavealpha($image, true); imagepng($image, $destfile); imagedestroy($image); Previous Comments: ------------------------------------------------------------------------ [2007-06-12 11:11:44] cyberline at techno4ever dot net The fontfile: http://web1.server02.quadrat4.de/federation.ttf The logo: http://web1.server02.quadrat4.de/logo.png (I've tested other transparent PNG's with similar results) Further i've added a sample text with ./arial.ttf ------------------------------------------------------------------------ [2007-06-12 10:59:19] pajoye@php.net Please provide a link to the original "logo.png" image and to the TTF file. ------------------------------------------------------------------------ [2007-06-12 09:43:16] cyberline at techno4ever dot net Description: ------------ imageTTFtext has no alpha in case of using imageCreateFromPNG.
