cropping an image? [message #184581]

Does anyone know how to do cropping on an Image/ImageData/ImageFigure?

I'm using an extension of ImageFigure that stores an internal unaltered
ImageData. Whenever the user changes the bounds of the figure, the internal
Image is disposed and recreated to be rescaled to the new size from the
original ImageData (using scaleTo on ImageData)

I need to be able to know how to also do cropping of the image displayed,
and can't seem to find any methods readily available for doing this - does
anyone know how this should be done?

drawImage allows to "crop" the painting without having to actually crop the
actual image (btw, clipping does this for you already). Similarly, you can
scale an image while painting without having to recreate it.
