Detailed Description

template<class T = int>
class prapi::RGBColor< T >

A convenience class for the RGB color space.

RGB colors are represented as three component values. In fact, RGBColor can be used in with any three-dimensional color space. The default component class is int.

Public Methods
	RGBColor (T clr=0)
	Create a new RGB color with all channels set to clr.
	RGBColor (T r, T g, T b)
	Create a new RGB color with color channels set as indicated.
template<class U>	RGBColor (const Color< U, 3 > &other)
	Create a copy of an RGB color of any type.
	RGBColor (const Color< T, 3 > &other)
	The copy constructor.
	RGBColor (const HSVColor< T > &other)
	Transform a color in the HSV color space to the RGB color space.
T	getRed () const
	Get the value of the red color channel.
T	getGreen () const
	Get the value of the green color channel.
T	getBlue () const
	Get the value of the blue color channel.
void	setRed (T value)
	Set the red color channel.
void	setGreen (T value)
	Set the green color channel.
void	setBlue (T value)
	Set the blue color channel.
	operator int () const
	Convert an RGB color to an integer.
	operator float () const
	Convert an RGB color to a float.
	operator double () const
	Convert an RGB color to a double.
	operator HSVColor () const
	Convert an RGB color to HSV.
template<class U> RGBColor &	operator= (const Color< U, 3 > &other)
	Copy a color of any content type.
RGBColor &	operator= (const Color< T, 3 > &other)
	Copy a color.
RGBColor &	operator= (T value)
	Set all color channels to value.
RGBColor< double >	getNormalizedColor (void) const
	Get a normalized version of this color.

Member Function Documentation

template<class T> RGBColor< double > prapi::RGBColor< T >::getNormalizedColor (  void    )  const

Get a normalized version of this color. Each color channel is divided by the sum of all channels.

template<class T = int> prapi::RGBColor< T >::operator double (    )  const [inline]

Convert an RGB color to a double. The result is the intensity of this color, i.e. the average of R, G, and B.

template<class T = int> prapi::RGBColor< T >::operator float (    )  const [inline]

Convert an RGB color to a float. The result is the intensity of this color, i.e. the average of R, G, and B.

template<class T = int> prapi::RGBColor< T >::operator HSVColor (    )  const [inline]

Convert an RGB color to HSV. This method works correctly only when float or double is used as the content type and RGB color values are in the range [0,1], or when the content type is int, and coordinates are in the range [0,255].

template<class T = int> prapi::RGBColor< T >::operator int (    )  const [inline]

Convert an RGB color to an integer. The result is the intensity of this color, i.e. the average of R, G, and B.
