- Parameters
-
| [in] | hue | The hue HSL-component |
| [in] | saturation | The saturation HSL-component |
| [in] | luminance | The luminance HSL-component |

| |
|
static |
Translates an HSV (hue, saturation, value) color to an RGB (red, green, blue) color.
- Parameters
-
| [in] | hue | The hue HSV-component |
| [in] | saturation | The saturation HSV-component |
| [in] | value | The value HSV-component |
| [out] | red | The red RGB-component |
| [out] | green | The green RGB-component |
| [out] | blue | The blue RGB-component |
- Note
- Integer version of the conversion are faster, but a little less accurate all values are unsigned 8 bit values and scaled between 0 and 255 except for the hue which is a 16 bit number and scaled between 0 and 360
