Detailed Description

Color in CIE 1931 XYZ color space The CIE XYZ color space is the master for the derived CIE Lab color space, which is perceptually uniform and hence will be used more often for visualization purposes.

Note

Since the CIE XYZ color space is larger than the RGB space, some XYZ colors cannot be represented by a corresponding RGB color. Hence, a conversation to a RGB color may result in a RGB color that is out of bounds.

Constructor & Destructor Documentation

XYZ() [1/2]

XYZ ( float  ix, float  iy, float  iz  )

inline

Constructs color in CIE 1931 XYZ color space X: from 0 to 95.047 Y: from 0 to 100.000 Z: from 0 to 108.883.

XYZ() [2/2]

XYZ ( )

inline

Default constructor Initializes X,Y, and Z with 0.0.

Member Function Documentation

reflect()

void reflect ( Reflector &  r )

inline

toRGB()

virtual Color::RGB toRGB ( ) const

inlinevirtual

Converts the CIE XYZ color to RGB.

Note

Since the CIE XYZ color space is larger than the RGB space, the components of the resulting RGB color may be out of their valid ranges, i.e. some components may be negative or larger than 1.0. This happens, if a XYZ color cannot be represented by a RGB color. The range of the returned RGB color can be checked using the isInRange() method.

Implements ColorBase.

operator cv::Scalar()

operator cv::Scalar ( ) const

inlinevirtualinherited

converts color to cv::Scalar Converts color to cv::Scalar by first converting to RGB and then creating a 4 channel cv::Scalar(B,G,R,255);

cast operator to cv::Scalar converts color to OpenCV BGRA format by scaling range to 0..255 and setting alpha channel to 255

Reimplemented in RGBA.
