Detailed Description

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 & Destructor Documentation

QwtSaturationValueColorMap::QwtSaturationValueColorMap ( )

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.

int QwtSaturationValueColorMap::hue ( ) const
Returns
Hue coordinate

QRgb QwtSaturationValueColorMap::rgb ( const QwtInterval interval,
double  value 
) const
virtual

Map a value of a given interval into a RGB value

Parameters
intervalRange for all values
valueValue to map into a RGB value
Returns
RGB value for value

Implements QwtColorMap.

Definition at line 1185 of file qwt_color_map.cpp.

int QwtSaturationValueColorMap::saturation1 ( ) const
Returns
First saturation coordinate
See also
setSaturationInterval()

Definition at line 1136 of file qwt_color_map.cpp.

int QwtSaturationValueColorMap::saturation2 ( ) const
Returns
Second saturation coordinate
See also
setSaturationInterval()

Definition at line 1145 of file qwt_color_map.cpp.

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.

Parameters
alphaAlpha coordinate
See also
alpha()

Definition at line 1112 of file qwt_color_map.cpp.

void QwtSaturationValueColorMap::setHue ( int  hue)

Set the the hue coordinate.

Hue coordinates ouside 0 to 359 will be interpreted as hue % 360..

Parameters
hueHue coordinate
See also
hue()

Definition at line 1037 of file qwt_color_map.cpp.

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.

Parameters
saturation1First saturation
saturation2Second saturation
See also
saturation1(), saturation2(), setValueInterval()

Definition at line 1061 of file qwt_color_map.cpp.

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.

Parameters
value1First value
value2Second value
See also
value1(), value2(), setSaturationInterval()

Definition at line 1088 of file qwt_color_map.cpp.

int QwtSaturationValueColorMap::value1 ( ) const
Returns
First value coordinate
See also
setValueInterval()

Definition at line 1154 of file qwt_color_map.cpp.

int QwtSaturationValueColorMap::value2 ( ) const
Returns
Second value coordinate
