in Haskell before blitting the data (whilst also retaining some semblance of functional programming...)
the best way to optimize Haskell program (with current technologies) is to rewrite it in strict & imperative manner:
cam_snap_3 cam f x = let end = snap_size cam loop ptr n x | ptr `seq` n `seq` x `seq` False = undefined | n >= end = return x | otherwise = do r <- peek ptr g <- peek (advancePtr ptr 1) b <- peek (advancePtr ptr 2) loop (advancePtr ptr 3) (n+3) (f r g b n x) in loop (cam_img cam) 0 x
