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.
The PHPInfo from the server can be found here:
