object Image.AVS.decode(string data) mapping Image.AVS._decode(string data) string Image.AVS.encode(object image)
Handle encoding and decoding of AVS-X images. AVS is rather trivial, and not really useful, but:
An AVS file is a raw (uncompressed) 24 bit image file with alpha. The alpha channel is 8 bit, and there is no separate alpha for r, g and b.
