Class: QgsFillSymbolLayer

class qgis.core.QgsFillSymbolLayer(locked: bool = False)

Bases: QgsSymbolLayer

Methods

angle	Returns the rotation angle of the fill symbol, in degrees clockwise.
copyDataDefinedProperties	Copies all data defined properties of this layer to another symbol layer.
copyPaintEffect	Copies paint effect of this layer to another symbol layer
drawPreviewIcon	param context:
installMasks	When rendering, install masks on context painter if recursive is True masks are installed recursively for all children symbol layers
removeMasks	When rendering, remove previously installed masks from context painter if recursive is True masks are removed recursively for all children symbol layers
renderPolygon	Renders the fill symbol layer for the polygon whose outer ring is defined by points, using the given render context.
restoreOldDataDefinedProperties	Restores older data defined properties from string map.
setAngle	Sets the rotation angle of the pattern, in degrees clockwise.
shouldRenderUsingSelectionColor	Returns True if the symbol layer should be rendered using the selection color from the render context.
toTiledPatternImage	Renders the symbol layer as an image that can be used as a seamless pattern fill for polygons, this method is used by SLD export to generate image tiles for ExternalGraphic polygon fills.

angle(self) → float

Returns the rotation angle of the fill symbol, in degrees clockwise.

Note

Not all fill symbol layers support rotation.

renderPolygon(self, points: QPolygonF, rings: Iterable[QPolygonF], context: QgsSymbolRenderContext)

Renders the fill symbol layer for the polygon whose outer ring is defined by points, using the given render context.

The rings argument optionally specifies a list of polygon rings to render as holes.

Parameters:

• points (QPolygonF) –

• rings (Iterable[QPolygonF]) –

• context (QgsSymbolRenderContext) –

restoreOldDataDefinedProperties(self, stringMap: Dict[str, Any])

Restores older data defined properties from string map.

New in version 3.0.

setAngle(self, angle: float)

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

Note

Not all fill symbol layers support rotation.

angle()

Parameters:

angle (float) –

shouldRenderUsingSelectionColor(self, context: QgsSymbolRenderContext) → bool

Returns True if the symbol layer should be rendered using the selection color from the render context.

New in version 3.34.

toTiledPatternImage(self) → QImage

Renders the symbol layer as an image that can be used as a seamless pattern fill for polygons, this method is used by SLD export to generate image tiles for ExternalGraphic polygon fills.

The default implementation returns a null image.

Return type:

QImage

Returns:

the tile image (not necessarily a square) or a null image if not implemented.

New in version 3.30.
