QwtSaturationValueColorMap varies the saturation and/or value for a given hue in the HSV color model.
Value and saturation are in the range of 0 to 255 while hue is inthe range of 0 to 259.

Constructor.
The value interval is initialized by 0 to 255, saturation by 255 to 255. Hue to 0 and alpha to 255.
So the default setting interpolates the value coordinate only.

void QwtSaturationValueColorMap::setAlpha | ( | int | alpha | ) |
Set the the alpha coordinate.
alpha needs to be in the range 0 to 255, where 255 means opaque and 0 means transparent.
alpha | Alpha coordinate |

void QwtSaturationValueColorMap::setHue | ( | int | hue | ) |
Set the the hue coordinate.
Hue coordinates ouside 0 to 359 will be interpreted as hue % 360..
hue | Hue coordinate |

void QwtSaturationValueColorMap::setSaturationInterval | ( | int | saturation1, |
int | saturation2 | ||
) |
Set the interval for the saturation coordinate.
When saturation1 == saturation2 the map interpolates between the value coordinates only
saturation1/saturation2 need to be in the range 0 to 255.
saturation1 | First saturation |
saturation2 | Second saturation |

void QwtSaturationValueColorMap::setValueInterval | ( | int | value1, |
int | value2 | ||
) |
Set the interval for the value coordinate.
When value1 == value2 the map interpolates between the saturation coordinates only.
value1/value2 need to be in the range 0 to 255.
value1 | First value |
value2 | Second value |
