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.

QGIS 3.24

Definition at line 73 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

Definition at line 59 of file qgscolorrampimpl.h.

operator==()

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

inline

Definition at line 54 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.
