NAME

       SbColor -

       The SbColor class contains the red, green and blue components which make up a color value.

       This class is used within other classes in Coin. It inherits the SbVec3f class,
       interpreting the 3 component vector as a vector in the RGB cube where the red, green and
       blue components corresponds to x, y and z respectively.

SYNOPSIS

       #include <Inventor/SbColor.h>

       Inherits SbVec3f.

Detailed Description

       The SbColor class contains the red, green and blue components which make up a color value.

       This class is used within other classes in Coin. It inherits the SbVec3f class,
       interpreting the 3 component vector as a vector in the RGB cube where the red, green and
       blue components corresponds to x, y and z respectively.

       SbColor also adds a few extra methods for convenient handling of setting and getting color
       values as 32 bit packed values or as HSV values.

Constructor & Destructor Documentation

   SbColor::SbColor (void)
       Default constructor. The color value will be uninitialized.

   SbColor::SbColor (const SbVec3f &v)
       Construct and initialize an SbColor with the red, green and blue values given by the v
       vector.

   SbColor::SbColor (const float *constrgb)
       Construct and initialize an SbColor with the red, green and blue taken from given rgb
       array.

   SbColor::SbColor (const floatr, const floatg, const floatb)
       Construct and initialize an SbColor with the given red, green and blue values.

Member Function Documentation

   SbColor & SbColor::setHSVValue (floathue, floatsaturation, floatvalue)
       Set the color as a hue, saturation, value triplet. The hue component should be normalized
       to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to
       360°.

       See Also:
           getHSVValue().

   SbColor & SbColor::setHSVValue (const floathsv[3])
       Set the color as a hue, saturation, value triplet. The hue component should be normalized
       to within [0, 1] before you call this method, where 0 is equal to 0° and 1 is equal to
       360°.

       See Also:
           getHSVValue().

   void SbColor::getHSVValue (float &h, float &s, float &v) const
       Return the color as a hue, saturation, value triplet.

       See Also:
           setHSVValue().

   void SbColor::getHSVValue (floathsv[3]) const
       Return the color as a hue, saturation, value triplet.

       See Also:
           setHSVValue().

   SbColor & SbColor::setPackedValue (const uint32_trgba, float &transparency)
       Set the color value as a 32 bit combined red/green/blue/alpha value. Each component is 8
       bit wide (i.e. from 0x00 to 0xff), and the red value should be stored leftmost, like this:
       0xRRGGBBAA.

       The transparency value is not stored internally in SbColor, just converted to a
       transparency value in [0, 1] and returned in the transparency field. A value of 1.0 means
       completely transparent and a value of 0.0 is completely opaque.

       See Also:
           getPackedValue().

   uint32_t SbColor::getPackedValue (const floattransparency = 0.0f) const
       Return color as a 32 bit packed integer in the form 0xRRGGBBAA. The transparency part of
       the return value is taken from the supplied transparency argument.

       See Also:
           setPackedValue().
