#21265 [NEW]: unexpected low color depth

From: tho.r@gmx.net Operating system: Linux PHP version: 4.3.0 PHP Bug Type: GD related Bug description: unexpected low color depth Hi! Before switching to PHP 4.3.0 we could create a "nice" colored thumbnail from an image via PHP and GD (1.8.x) with the following code: $thumb = imagecreate($twidth, $theight); $orig = @imagecreatefromjpeg($file); if (!$orig) { echo "Couldn't load JPEG image '$file'."; exit(); } imagecopyresized($thumb, $orig, 0, 0, 0, 0, $twidth, $theight, $width, $height); mkdir(dirname($thumbnail),0777); imagejpeg($thumb,$thumbnail,65); We had a switch statement for any supported image type (JPEG, GIF and PNG). The created image is of course smaller but has the same color depth as the original. After using PHP 4.3.0 and its bundled GD2 library the image is also created but the result has very less colors (maybe 16). I've put an example here: http://thoralf.log-out.net/tmp/php4.3.0.html I'm not sure, if I did a mistake or if there is something missing now - but it works with PHP4.2.2 very well.
