virtual ~QwtSaturationValueColorMap ()
Destructor.
void setHue (int hue)
Set the the hue coordinate.
void setSaturationInterval (int sat1, int sat2)
Set the interval for the saturation coordinate.
void setValueInterval (int value1, int value2)

virtual QRgb rgb (const QwtInterval &, double value) const override

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.

Set the the alpha coordinate. alpha needs to be in the range 0 to 255, where 255 means opaque and 0 means transparent.

Parameters

alpha Alpha coordinate

Set the the hue coordinate. Hue coordinates outside 0 to 359 will be interpreted as hue % 360..

Parameters

hue Hue coordinate

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.

Parameters

saturation1 First saturation
saturation2 Second saturation
