Class: QgsSimpleMarkerSymbolLayerBase¶

class qgis.core.QgsSimpleMarkerSymbolLayerBase(shape: QgsSimpleMarkerSymbolLayerBase.Shape = QgsSimpleMarkerSymbolLayerBase.Circle, size: float = DEFAULT_SIMPLEMARKER_SIZE, angle: float = DEFAULT_SIMPLEMARKER_ANGLE, scaleMethod: QgsSymbol.ScaleMethod = DEFAULT_SCALE_METHOD)¶

Bases: qgis._core.QgsMarkerSymbolLayer

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

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: Enums

Methods

`availableShapes`	Returns a list of all available shape types.
`bounds`
`decodeShape`	Attempts to decode a string representation of a shape name to the corresponding shape.
`encodeShape`	Encodes a shape to its string representation.
`renderPoint`
`setShape`	Sets the rendered marker shape.
`shape`	Returns the shape for the rendered marker symbol.
`shapeIsFilled`	Returns `True` if a symbol shape has a fill.
`startRender`
`stopRender`

availableShapes() → List[QgsSimpleMarkerSymbolLayerBase.Shape]¶: Returns a list of all available shape types.

bounds(self, point: Union[QPointF, QPoint], context: QgsSymbolRenderContext) → QRectF¶

decodeShape(name: str) → Tuple[QgsSimpleMarkerSymbolLayerBase.Shape, bool]¶

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

Parameters

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

Returns

decoded name
