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

ID: 41666 User updated by: cyberline at techno4ever dot net Reported By: cyberline at techno4ever dot net -Status: Bogus +Status: Open Bug Type: GD related Operating System: Debian 3.1 PHP Version: 5.2.3 Assigned To: pajoye New Comment: I don't mean the transparent background! My problem is the text. Compare: http://cyberline.ath.cx/phpbug/nok.php (PHP 5.2.1) with http://web1.server02.quadrat4.de/phpbug/nok.php (PHP 5.2.3) Both same Configure. Previous Comments: ------------------------------------------------------------------------ [2007-06-12 12:05:03] pajoye@php.net "So it is not a bug that in 5.2.1 the alpha was enabled by default " I don't have a 5.2.1 to test. The alpha channel is now preserved (the background, the white area around the logo). nok.php is black because you don't save the alpha channel. I think this bug is not a bug. I close (not a bug > bogus) it now. Please reopen it if you consider that it is not working correctly in 5.2.3 or using snapshot. ------------------------------------------------------------------------ [2007-06-12 11:54:58] cyberline at techno4ever dot net Now the 5.2.1 working Sample (nok.php) looks fine with imagesavealpha, but take a look at the ok.php with imagealphablending($image, 0); So it is not a bug that in 5.2.1 the alpha was enabled by default ? ------------------------------------------------------------------------ [2007-06-12 11:45:19] pajoye@php.net Ok, I understand what you mean now. There is two things. Per default gd does not save the alpha information, you have to enable this mode using: imagesavealpha($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); ------------------------------------------------------------------------ [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. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
