Class: QgsSimpleMarkerSymbolLayer¶

Simple marker symbol layer, consisting of a rendered shape with solid fill color and an stroke.

Class Hierarchy¶

Base classes¶

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

Methods

`calculateOffsetAndRotation`
`calculateSize`
`draw`
`drawMarker`	Draws the marker shape in the specified painter.
`penCapStyle`	Returns the marker's stroke cap style (e.g., flat, round, etc).
`penJoinStyle`	Returns the marker's stroke join style (e.g., miter, bevel, etc).
`prepareCache`	Prepares cache image
`prepareMarkerPath`
`prepareMarkerShape`
`setPenCapStyle`	Sets the marker's stroke cap style (e.g., flat, round, etc).
`setPenJoinStyle`	Sets the marker's stroke join style (e.g., miter, bevel, etc).
`setStrokeColor`	Sets the marker's stroke color.
`setStrokeStyle`	Sets the marker's stroke style (e.g., solid, dashed, etc)
`setStrokeWidth`	Sets the width of the marker's stroke.
`setStrokeWidthMapUnitScale`	Sets the map scale for the width of the marker's stroke.
`setStrokeWidthUnit`	Sets the unit for the width of the marker's stroke.
`shapeToPolygon`
`strokeColor`	Returns the marker's stroke color.
`strokeStyle`	Returns the marker's stroke style (e.g., solid, dashed, etc)
`strokeWidth`	Returns the width of the marker's stroke.
`strokeWidthMapUnitScale`	Returns the map scale for the width of the marker's stroke.
`strokeWidthUnit`	Returns the unit for the width of the marker's stroke.

Static Methods

`create`	Creates a new QgsSimpleMarkerSymbolLayer.
`createFromSld`	Creates a new `QgsSimpleMarkerSymbolLayer` from an SLD XML element.

class qgis.core.QgsSimpleMarkerSymbolLayer[source]¶

Bases: QgsSimpleMarkerSymbolLayerBase

__init__(shape: Qgis.MarkerShape = Qgis.MarkerShape.Circle, size: float = DEFAULT_SIMPLEMARKER_SIZE, angle: float = DEFAULT_SIMPLEMARKER_ANGLE, scaleMethod: Qgis.ScaleMethod = DEFAULT_SCALE_METHOD, color: QColor | Qt.GlobalColor = DEFAULT_SIMPLEMARKER_COLOR, strokeColor: QColor | Qt.GlobalColor = DEFAULT_SIMPLEMARKER_BORDERCOLOR, penJoinStyle: Qt.PenJoinStyle = DEFAULT_SIMPLEMARKER_JOINSTYLE)

Constructor for QgsSimpleMarkerSymbolLayer.

Parameters:

shape (Qgis.MarkerShape = Qgis.MarkerShape.Circle) – symbol shape
size (float = DEFAULT_SIMPLEMARKER_SIZE) – symbol size (in mm)
angle (float = DEFAULT_SIMPLEMARKER_ANGLE) – symbol rotation angle
scaleMethod (Qgis.ScaleMethod = DEFAULT_SCALE_METHOD) – scaling method for data defined scaling
color (Union[QColor, Qt.GlobalColor] = DEFAULT_SIMPLEMARKER_COLOR) – fill color for symbol
strokeColor (Union[QColor, Qt.GlobalColor] = DEFAULT_SIMPLEMARKER_BORDERCOLOR) – stroke color for symbol
penJoinStyle (Qt.PenJoinStyle = DEFAULT_SIMPLEMARKER_JOINSTYLE) – join style for stroke pen

calculateOffsetAndRotation()¶

calculateSize()¶

static create(properties: Dict[str, Any] = {}) → QgsSymbolLayer | None[source]¶

Creates a new QgsSimpleMarkerSymbolLayer.

Parameters:: properties (Dict[str, Any] = {}) – a property map containing symbol properties (see properties())
Return type:: Optional[QgsSymbolLayer]
Returns:: new QgsSimpleMarkerSymbolLayer

static createFromSld(element: QDomElement) → QgsSymbolLayer | None[source]¶

Creates a new QgsSimpleMarkerSymbolLayer from an SLD XML element.

Parameters:: element (QDomElement) – XML element containing SLD definition of symbol
Return type:: Optional[QgsSymbolLayer]
Returns:: new QgsSimpleMarkerSymbolLayer
