Member Function Documentation

§ ComputeLuminance()

float LinearColor::ComputeLuminance ( ) const

Computes the perceptually weighted luminance value of a color.

§ Desaturate()

LinearColor LinearColor::Desaturate ( float Desaturation ) const

Returns a desaturated color, with 0 meaning no desaturation and 1 == full desaturation.

Parameters

Desaturation Desaturation factor in range [0..1]

Returns: Desaturated color

§ GetMax()

float ParaEngine::LinearColor::GetMax ( ) const

inline

Returns the maximum value in this color structure.

Returns: The maximum color channel value

§ GetMin()

float ParaEngine::LinearColor::GetMin ( ) const

inline

Returns the minimum value in this color structure.

Returns: The minimum color channel value

§ Quantize()

Color LinearColor::Quantize ( ) const

Quantizes the linear color and returns the result as a color.

This bypasses the SRGB conversion.

§ ToColor()

Color LinearColor::ToColor ( bool bSRGB = false ) const

Quantizes the linear color and returns the result as a color with optional sRGB conversion and quality as goal.

Quantizes the linear color and returns the result as a Color with optional sRGB conversion and quality as goal.
