I am seeing this on the status page of D6 on my Ubuntu server.
Does anyone know of a Ubuntu package that will solve this, or must I actually compile my own PHP here?
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. GD Image Rotation Low Quality / Poor Performance The installed version of PHP GD does not support image rotations. 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.
