Constructor & Destructor Documentation

◆ QgsGradientStop()

QgsGradientStop::QgsGradientStop ( double  offset,

offsetpositional offset for stop, between 0 and 1.0
colorcolor for stop

Definition at line 179 of file qgscolorrampimpl.cpp.

Member Function Documentation

◆ colorSpec()

QColor::Spec QgsGradientStop::colorSpec ( ) const
inline

Returns the color specification in which the color component interpolation will occur.

For multi-stop gradients this color spec will be used for the portion of the color ramp leading into the current stop.

setColorSpec()
Since
QGIS 3.24

Definition at line 72 of file qgscolorrampimpl.h.

◆ direction()

Qgis::AngularDirection QgsGradientStop::direction ( ) const
inline

Returns the direction to traverse the color wheel using when interpolating hue-based color specifications.

For multi-stop gradients this direction will be used for the portion of the color ramp leading into the current stop.

◆ operator!=()

bool QgsGradientStop::operator!= ( const QgsGradientStop &  other) const
inline

Definition at line 58 of file qgscolorrampimpl.h.

◆ operator==()

bool QgsGradientStop::operator== ( const QgsGradientStop &  other) const
inline

Definition at line 53 of file qgscolorrampimpl.h.

◆ setColorSpec()

void QgsGradientStop::setColorSpec ( QColor::Spec  spec)

Sets the color specification in which the color component interpolation will occur.

Only QColor::Spec::Rgb, QColor::Spec::Hsv and QColor::Spec::Hsl are currently supported.

For multi-stop gradients this color spec will be used for the portion of the color ramp leading into the current stop.

◆ setDirection()

void QgsGradientStop::setDirection ( Qgis::AngularDirection  direction)
inline

Sets the direction to traverse the color wheel using when interpolating hue-based color specifications.

For multi-stop gradients this direction will be used for the portion of the color ramp leading into the current stop.
