GD Image Filtering and Image Rotation Libraries incompatible Drupal6 Appliance

GD Image Filtering

Low Quality / Poor Performance

The installed version of PHP GD does not support image filtering(desaturate, blur, negate, etc). It was probably compiled using the official GD libraries from http://www.libgd.org instead of the GD library bundled with PHP. You should recompile PHP --with-gd using the bundled GD library. See http://www.php.net/manual/en/image.setup.php. An implementation of imagefilter in PHP will be used in the interim.

We use the php5-gd Ubuntu package

We use the php5-gd packaged by Ubuntu, which is inherited from Debian. We did not compile GD support ourselves. If this is a bug it should be reported upstream.

On the other hand, you mentioned that we should use the GD library bundled with PHP, so I guess you have come across this issue before. We should look into that as a work around, but the best solution would to get this fixed upstream in the official packages.
