Class: QgsSimpleMarkerSymbolLayerBase¶

class qgis.core.QgsSimpleMarkerSymbolLayerBase¶

Bases: QgsMarkerSymbolLayer

Abstract base class for simple marker symbol layers. Handles creation of the symbol shapes but leaves the actual drawing of the symbols to subclasses.

New in version 2.16.

QgsSimpleMarkerSymbolLayerBase(shape: Qgis.MarkerShape = Qgis.MarkerShape.Circle, size: float = DEFAULT_SIMPLEMARKER_SIZE, angle: float = DEFAULT_SIMPLEMARKER_ANGLE, scaleMethod: Qgis.ScaleMethod = DEFAULT_SCALE_METHOD) Constructor for QgsSimpleMarkerSymbolLayerBase.

Parameters:

shape – symbol shape for markers
size – symbol size (in mm)
angle – symbol rotation angle

scaleMethod –

scaling method for data defined scaling

Enums

Shape

alias of MarkerShape

Shape¶: alias of MarkerShape

availableShapes() → List[Qgis.MarkerShape]¶

Returns a list of all available shape types.

Return type:: List[Qgis.MarkerShape]

bounds(self, point: QPointF | QPoint, context: QgsSymbolRenderContext) → QRectF¶

Parameters:

point (Union[QPointF) –
context (QgsSymbolRenderContext) –

Return type:

QRectF

decodeShape(name: str) → Tuple[Qgis.MarkerShape, bool]¶

Attempts to decode a string representation of a shape name to the corresponding shape.

Parameters:

name (str) – encoded shape name
ok – if specified, will be set to True if shape was successfully decoded

Return type:

Tuple[Qgis.MarkerShape, bool]

Returns:

decoded name
