Constructor & Destructor Documentation

◆ QgsRasterFillSymbolLayer()

QgsRasterFillSymbolLayer::QgsRasterFillSymbolLayer ( const QString &  imageFilePath = QString())

Constructor for QgsRasterFillSymbolLayer, using a raster fill from the specified imageFilePath.

Member Function Documentation

◆ applyBrushTransformFromContext()

bool QgsRasterFillSymbolLayer::applyBrushTransformFromContext ( QgsSymbolRenderContext context = nullptr) const
overrideprotectedvirtual

Returns true if the image brush should be transformed using the render context's texture origin.

Since
QGIS 3.16

Reimplemented from QgsImageFillSymbolLayer.

Definition at line 4932 of file qgsfillsymbollayer.cpp.

◆ applyDataDefinedSettings()

void QgsRasterFillSymbolLayer::applyDataDefinedSettings ( QgsSymbolRenderContext context)
overrideprotectedvirtual

Applies data defined settings prior to generating the fill symbol brush.

Reimplemented from QgsImageFillSymbolLayer.

Definition at line 4882 of file qgsfillsymbollayer.cpp.

◆ clone()

QgsRasterFillSymbolLayer * QgsRasterFillSymbolLayer::clone ( ) const
overridevirtual

Shall be reimplemented by subclasses to create a deep copy of the instance.

Implements QgsSymbolLayer.

Definition at line 4834 of file qgsfillsymbollayer.cpp.

◆ color()

QColor QgsRasterFillSymbolLayer::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).

setColor()
strokeColor()
fillColor()

Reimplemented from QgsSymbolLayer.

Definition at line 4862 of file qgsfillsymbollayer.cpp.

Definition at line 4686 of file qgsfillsymbollayer.cpp.

◆ estimateMaxBleed()

double QgsRasterFillSymbolLayer::estimateMaxBleed ( const QgsRenderContext context) const

Returns the estimated maximum distance which the layer style will bleed outside the drawn shape when drawn in the specified /a context.

For example, polygons drawn with an stroke will draw half the width of the stroke outside of the polygon. This amount is estimated, since it may be affected by data defined symbology rules.
