1. pixelMap :: (Pixel a, Pixel b) => (a -> b) -> Image a -> Image b

   JuicyPixels	Codec.Picture.Types

   map equivalent for an image, working at the pixel level. Little example : a brightness function for an rgb image

   brightnessRGB8 :: Int -> Image PixelRGB8 -> Image PixelRGB8
   brightnessRGB8 add = pixelMap brightFunction
   where up v = fromIntegral (fromIntegral v + add)
   brightFunction (PixelRGB8 r g b) =
   PixelRGB8 (up r) (up g) (up b)
   

2. pixelMapXY :: (Pixel a, Pixel b) => (Int -> Int -> a -> b) -> Image a -> Image b

   JuicyPixels	Codec.Picture.Types

   Just like pixelMap only the function takes the pixel coordinates as additional parameters.

3. toneMapping :: PixelF -> Image PixelRGBF -> Image PixelRGBF

   JuicyPixels	Codec.Picture.Types

   Perform a tone mapping operation on an High dynamic range image.

4. parMap :: Strategy b -> (a -> b) -> [a] -> [b]

   parallel	Control.Parallel.Strategies

   A combination of parList and map, encapsulating a common pattern:

   parMap strat f = withStrategy (parList strat) . map f
   

5. seqMap :: Strategy k -> Strategy v -> Strategy (Map k v)

   parallel	Control.Seq

   Evaluate the keys and values of a map according to the given strategies.

6. contramapRep :: Representable f => (a -> b) -> f b -> f a

   adjunctions	Data.Functor.Contravariant.Rep

   No documentation available.

7. contramapWithRep :: Representable f => (b -> Either a (Rep f)) -> f a -> f b

   adjunctions	Data.Functor.Contravariant.Rep

   contramapWithRep f p ≡ tabulate $ either (index p) id . f
   

8. fmapRep :: Representable f => (a -> b) -> f a -> f b

   adjunctions	Data.Functor.Rep

   No documentation available.

9. ifoldMapRep :: (Representable r, Foldable r, Monoid m) => (Rep r -> a -> m) -> r a -> m

   adjunctions	Data.Functor.Rep

   No documentation available.

10. imapRep :: Representable r => (Rep r -> a -> a') -> r a -> r a'

    adjunctions	Data.Functor.Rep

    No documentation available.
