◆ bounds()

QRectF QgsMaskMarkerSymbolLayer::bounds	(	QPointF	point,
		QgsSymbolRenderContext &	context
	)

overridevirtual

Returns the approximate bounding box of the marker symbol layer, taking into account any data defined overrides and offsets which are set for the marker layer.

Returns: approximate symbol bounds, in painter units

Definition at line 139 of file qgsmasksymbollayer.cpp.

◆ clone()

◆ color()

QColor QgsMaskMarkerSymbolLayer::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).
