Delayed images
A delayed image is an image which is constructed using a function.
Usually, a delayed image maps each of its pixels over another image. Delayed images are useful by avoiding intermediate images in a transformation pipeline of images or by avoiding the computation of the whole resulting image when only a portion of its pixels will be accessed.

Conversion and type helpers
delay :: Image i => i -> Delayed (ImagePixel i) Source
Delays an image in its delayed representation.
compute :: (Image i, Storable (ImagePixel i)) => i -> Manifest (ImagePixel i) Source
