Detailed Description

Color in RGBA color space.

Constructor & Destructor Documentation

RGBA() [1/4]

RGBA ( float  ir, float  ig, float  ib, float  ia  )

inline

Constructs RGBA color R,G,B and A: range from 0.0 to 1.0.

RGBA() [2/4]

RGBA ( )

inline

Default constructor that creates a black color.

RGBA() [3/4]

RGBA ( const RGBA &  other )

inline

copy constructor

RGBA() [4/4]

RGBA ( const RGB &  other, float  ia = 1.0f  )

inline

Constructs RGBA color from RGB color and alpha value (that is 1.0f per default).

Member Function Documentation

reflect()

void reflect ( Reflector &  r )

inline

operator cv::Scalar()

virtual operator cv::Scalar ( ) const

inlinevirtual

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 from ColorBase.

toRGB()

virtual Color::RGB toRGB ( ) const

inlinevirtualinherited

no conversion is done here, because it is already RGB

Implements ColorBase.

isInRange()

bool isInRange ( ) const

inlineinherited

Returns true, if all rgb components are within valid ranges, i.e.

between 0.0 and 1.0.

getClass()
