What about something like, import qualified Data.Vector.Unboxed as V import Data.Word type Pixel = (Word8, Word8, Word8) type Image = (Int, Int, V.Vector Pixel) Since you may want interoperability with C, you could also consider using Data.Vector.Storable with flat data. Just put the multi-dimensional logic in your indexing operations. I do quite a bit of image processing with a mix of Haskell and C, and have found Unboxed and Storable Vectors effective.
