    Change image saturation - GD2 or ImageMagick

    I'm doing some work involving combining PNGs and other various image manipulation functions and all is going well, except for one thing -- saturation.
    imagefilter() has just about everything OTHER than saturation and multiple searches haven't turned anything up. I need to be able to both increase and decrease saturation of a provided image.

    Has anyone managed this before? Got some code you can point me to?

    Thanks,
    Andrew.

    I take no responsibility for the above nonsense.

    The solution to this is to use the -modulate flag with ImageMagick.
