58 This class is used to represent an RGB color. Each component of the
59 vector is a floating-point number between 0.0 and 1.0. There are rou‐
60 tines to convert back and forth between RGB and HSV.

63 SbColor(const SbVec3f vec3f)
64 SbColor(const float rgb[3])
65 SbColor(float r, float g, float b)
66 Constructors for color vector.
67 SbColor & setHSVValue(float h, float s, float v)
69 Sets value of color vector from 3 HSV (Hue, Saturation, and Value)
70 components. Value is the same as brightness of the color.
71 SbColor & setHSVValue(const float hsv[3])
73 Sets value of color vector from array of 3 HSV components
74 void getHSVValue(float &h, float &s, float &v) const
76 Returns 3 individual HSV components
77 void getHSVValue(float hsv[3]) const
79 Returns an array of 3 HSV components
80 SbColor & setPackedValue(uint32_t rgba, float& transparency)
82 Sets value of color vector from an RGBA packed color value. The
83 packed color format expressed in hexadecimal is 0xrrggbbaa, where
84 rr is the red value
86 gg is the green value
87 bb is the blue value
88 aa is the alpha value
89 RGBA component values range from 0 to 0xFF (255). The returned
91 transparency value is a floating point value between 0.0 (opaque)
92 and 1.0 (completely transparent). It is derived from the alpha com‐
93 ponent of the RGBA color.
94 uint32_t getPackedValue(float transparency = 0.0) const
96 Returns an RGBA packed color value, derived from the color vector
97 and the passed transparency value. The alpha component is set to
98 (1.0 - transparency) * 255, resulting in a hex value between 0 and
99 0xFF. If transparency not specified, alpha is set to 0xFF (opaque).
