Description
Colours in the HSV (hue-saturation-value) cylindrical-coordinate representation of points in the RGB colour space.
Synopsis
- type Colour = HSV Float
- data HSV a = HSV a a a
- pattern HSV_ :: (Elt (HSV a), Elt a, VecElt a, EltR (HSV a) ~ Vec3 a) => Exp a -> Exp a -> Exp a -> Exp (HSV a)
- hsv :: Exp Float -> Exp Float -> Exp Float -> Exp Colour
- clamp :: Exp Colour -> Exp Colour
- toRGB :: Exp (HSV Float) -> Exp (RGB Float)
- fromRGB :: Exp (RGB Float) -> Exp (HSV Float)
- hue :: Exp (RGB Float) -> Exp Float
- saturation :: Exp (RGB Float) -> Exp Float
- value :: Exp (RGB Float) -> Exp Float

Instances
pattern HSV_ :: (Elt (HSV a), Elt a, VecElt a, EltR (HSV a) ~ Vec3 a) => Exp a -> Exp a -> Exp a -> Exp (HSV a) Source #
Arguments
| :: Exp Float | hue component |
| -> Exp Float | saturation component |
| -> Exp Float | value component |
| -> Exp Colour |
Construct a HSV colour value from the individual channel components. The hue component is measured in degrees and wrapped to the range [0..360), while the saturation and value are clamped to the range [0..1].
toRGB :: Exp (HSV Float) -> Exp (RGB Float) Source #
Convert a HSV colour to an RGB colour-space value
