readRGB

Arguments

:: Fun N3 Word8 a

Passed red, green, blue component in 0-255 range

-> Image

Image to import

-> UArray D L Dim2 a

Fuction to uniformly import images of any type.

Example:

anyImage <- readImage "lena.png"
let image = readRGB (\r g b -> ...) anyImage

readRGBVectors :: (Vector v Word8, Dim v ~ N3) => Image -> UArray D L Dim2 (v Word8)

readRGBVectors = readRGB construct
