They are supported by the camera and image_fx components.
If you wish to apply them to something other than the camera, create a MMAL (or IL if you must) pipeline with image_fx in, and you can then apply the effects.
That's great! I never knew there was an image_fx component. There doesn't seems to be any info on it in the mmal headers. Is there some documentation on it ? e.g. i would like to apply the blur filter to an image but would like to know what kind of blur (box, median, gaussian) and can i set a kernel size ?
