imColorLightness2Luminance float imColorLightness2Luminance(const(float) L): Converts Lightness (CIE L*) to Luminance (CIE Y) (all linear). \n * The white point is D65. \verbatim 0 <= Y <= 1 ; 0 <= L* <= 1
imColorLuminance2Lightness float imColorLuminance2Lightness(const(float) Y): Converts Luminance (CIE Y) to Lightness (CIE L*) (all linear). \n * The white point is D65. \verbatim 0 <= Y <= 1 ; 0 <= L* <= 1
imColorLuv2XYZ void imColorLuv2XYZ(float L, float u, float v, float X, float Y, float Z): Converts CIE L*u*v* (nonlinear) to CIE XYZ (linear). \n * The white point is D65. * 0 <= L <= 1 ; -0.5 <= uv <= +0.5 ; 0 <= XYZ <= 1 \n * \ingroup color
imColorMax int imColorMax(int data_type): Returns the maximum value for pre-defined color conversion purposes. \n * See \ref cci. * \ingroup color

imColorQuantize T imColorQuantize(const(float) value, const(T) min, const(T) max): Quantize 0-1 values into min-max. \n * Value are usually integers, * but the dummy quantizer uses real values. * See also \ref math. * \ingroup color
imColorRGB2Luma T imColorRGB2Luma(T R, T G, T B): Converts R'G'B' to Y' (all nonlinear). \n \verbatim Y' = 0.299 *R' + 0.587 *G' + 0.114 *B' \endverbatim * \ingroup color

imColorReconstruct float imColorReconstruct(const(T) value, const(T) min, const(T) max): Reconstruct min-max values into 0-1. \n * Values are usually integers, * but the dummy reconstructor uses real values. * See also \ref math. * \ingroup color
imColorTransfer2Linear float imColorTransfer2Linear(const(float) nonlinear_value): Converts nonlinear values to linear values. \n * We use the sRGB transfer function. sRGB uses ITU-R 709 primaries and D65 white point. \n \verbatim 0 <= l <= 1 ; 0 <= v <= 1
imColorTransfer2Nonlinear float imColorTransfer2Nonlinear(const(float) value): Converts linear values to nonlinear values. \n * We use the sRGB transfer function. sRGB uses ITU-R 709 primaries and D65 white point. \n \verbatim 0 <= l <= 1 ; 0 <= v <= 1
