Is “area” just a box filter, which is what it sounds like? If so, it gives really blurry results; hardly great.

Basically if you imagine overlaying the new square grid over the old one and then each new pixel gets a weighted combination of the overlapping old pixel squares, weighted by the overlap areas. To my eyes it's more pleasant than Lanczos, which has too much ringing.
