◆ angle()

double QgsPointPatternFillSymbolLayer::angle ( ) const

Returns the rotation angle of the pattern, in degrees clockwise.

Definition at line 2175 of file qgsfillsymbollayer.h.

◆ applyDataDefinedSettings()

void QgsPointPatternFillSymbolLayer::applyDataDefinedSettings ( QgsSymbolRenderContext context)
overrideprotectedvirtual

Applies data defined settings prior to generating the fill symbol brush.

Reimplemented from QgsImageFillSymbolLayer.

Definition at line 4281 of file qgsfillsymbollayer.cpp.

◆ clipMode()

◆ clone()

QgsPointPatternFillSymbolLayer * QgsPointPatternFillSymbolLayer::clone ( ) const
overridevirtual

Shall be reimplemented by subclasses to create a deep copy of the instance.

Implements QgsSymbolLayer.

Definition at line 4199 of file qgsfillsymbollayer.cpp.

◆ color()

QColor QgsPointPatternFillSymbolLayer::color ( ) const
overridevirtual

Returns the "representative" color of the symbol layer.

Depending on the symbol layer type, this will have different meaning. For instance, a line symbol layer will generally return the stroke color of the layer, while a fill symbol layer will return the "fill" color instead of stroke.

Some symbol layer types will return an invalid QColor if they have no representative color associated (e.g. raster image based symbol layers).
