Comments:
The class ByteRGBXValueC represents colour by a quadruple of integer numbers inside of the range 0-255. The quadruple is related to the general RGB representation of colour. This colour is useful mainly for building applications with colour grabbers.

public ByteRGBValueC

ByteGreyValueT fourthX;

The fourth component of the colour.

ByteRGBXValueC(GreyValueT r = BLACK,GreyValueT g = BLACK,GreyValueT b = BLACK,GreyValueT x = BLACK)

Constructs a colour from four colour component. This constructor serves also as the default constructor.

ByteRGBXValueC(const ByteRGBXValueC & rgbx)

The copy constructor.

ByteRGBXValueC(const ByteRGBValueC & rgb,GreyValueT x = BLACK)

Creates the colour from the triple RGB colour 'rgb' and the fourth colour component 'x'.

ByteRGBXValueC(const RGBValueC & rgb,GreyValueT x = BLACK)

Creates the colour from the RGB colour of the different range.

ByteRGBXValueC(const Point3dC & p,GreyValueT x = BLACK)

Creates the colour from three coordinates of the point 'p'.

const ByteRGBXValueC & Set(GreyValueT r,GreyValueT g,GreyValueT b,GreyValueT x = BLACK)

Sets the red, green, blue, and X colour compoments according to the values 'r', 'g', 'b', and 'x' respectively. Access to the colour components -------------------------------

ByteGreyValueT & X()

Access to the fourth colour component.

const ByteGreyValueT & X() const

Returns the level of the fourth colour component.

const ByteRGBValueC & Set(GreyValueT r,GreyValueT g,GreyValueT b)

Sets the red, green, and blue colour compoments according to the values 'r', 'g', and 'b', respectively. Logical operators -----------------

BooleanT operator==(const ByteRGBValueC & rgb) const

Returns TRUE if this colour is equal to the colour 'rgb'.

BooleanT IsSaturated() const

Returns TRUE if any colour component is equal to the level 255. Access to the colour components -------------------------------

const ByteGreyValueT & Red() const

Returns the level of the red component.

const ByteGreyValueT & Green() const

Returns the level of the green component.

const ByteGreyValueT & Blue() const

Returns the level of the blue component.

RealGreyValueT Y() const

Returns the intensity.

ByteGreyValueT & Red()

Access to the red component.

ByteGreyValueT & Green()

Access to the green component.

ByteGreyValueT & Blue()

Access to the blue component.

Point3dC Point() const

Returns RGB components represented as 3D point. Colour mixing -------------

const ByteRGBValueC & operator+=(const ByteRGBValueC & rgb)

Adds 'rgb' color to this color and truncates this color.

const ByteRGBValueC & operator-=(const ByteRGBValueC & rgb)

Subtracts 'rgb' color from this color and truncates this color.

IntT AbsDistance(const ByteRGBValueC & rgb) const

Returns colour distance.

UIntT Hash(void) const

Generate a hash value for this index.
