¤ queryColor, queryColorF

Types

queryColor :: (FudgetIO c) => ColormapId -> Pixel -> (Color -> c a b) -> c a b
queryColorF :: ColormapId -> Pixel -> Cont (F a b) Color

queryColor colormap pixel colkernel

data Color = Color Pixel RGB

data Pixel = Pixel Int

These functions allow you to find out what color a given pixel value defines in a colormap.

colormap :: ColormapId: a colormap
pixel :: Pixel: a pixel value
colkernel :: Color -> c a b: a fudget kernel continuation (or fudget in case of queryColorF) parameterized by the returned color.
