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.

Definition at line 206 of file qwt_color_map.h.

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.

Member Function Documentation

int QwtSaturationValueColorMap::alpha ( ) const

Returns:: Alpha coordinate

See also:: setAlpha()

Definition at line 1172 of file qwt_color_map.cpp.

int QwtSaturationValueColorMap::hue ( ) const

Returns:: Hue coordinate

See also:: setHue()

Definition at line 1127 of file qwt_color_map.cpp.

QRgb QwtSaturationValueColorMap::rgb	(	const QwtInterval &	interval,
		double	value
	)		const `[virtual]`

Map a value of a given interval into a RGB value

Parameters:

interval	Range for all values
value	Value 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:

alpha Alpha 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:

hue	Hue 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:

saturation1	First saturation
saturation2	Second 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:

value1	First value
value2	Second 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

See also:: setValueInterval()

Definition at line 1163 of file qwt_color_map.cpp.
