Colour Plane Extraction

[Gnome2013]

How do I extract the HSL Luminance Plane for an image using Java code? There doesn't seem to be a method to do so. I can find it for things like a convex hull or colour threshold but not the colour plane extraction.

The plane extraction functions are all located in the ColorImage class. It sounds like you are looking for getLuminancePlane()
