V3 image.get() and image.copy()

@sim - looking at image.get() and image copy() commands in V3, they appear to be valid commands (correctly colour coded) but throw up errors when I try to use them. Have they been modified, removed or replaced by other commands ? (or am I not using the correct syntax)

r,g,b = image.get(100, 100)
grab = image.copy(100,100,100,100)
