Perhaps functions of the form
encodePNG :: Image -> [Word8] decodePNG :: [Word8] -> Maybe Image
Or, somewhat more generally: -- probably elsewhere in the hierarchy class FileFormat a where encode :: a -> [Word8] decode :: [Word8] -> a instance FileFormat PNG where encode = ... decode = .. And perhaps: class Image a where rotate :: a -> Int -> a scale :: a -> Int -> Int -> a Maybe compose/blend images? Altering alpha and gamma, color manipulation? I guess it would be a good idea to look at some particular application implementations, and derive a useful library from that. Let's not invent another library that nobody knows how to use properly. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
