virtual void QgsImageFillSymbolLayer::applyDataDefinedSettings ( QgsSymbolV2RenderContext context)
QColor QgsImageFillSymbolLayer::dxfColor ( QgsSymbolV2RenderContext context) const

Reimplemented from QgsSymbolLayerV2.

Definition at line 1679 of file qgsfillsymbollayerv2.cpp.

Qt::PenStyle QgsImageFillSymbolLayer::dxfPenStyle ( ) const

Reimplemented from QgsSymbolLayerV2.

double QgsImageFillSymbolLayer::dxfWidth ( const QgsDxfExport e,
QgsSymbolV2RenderContext context 
) const

Reimplemented from QgsSymbolLayerV2.

Definition at line 1668 of file qgsfillsymbollayerv2.cpp.

double QgsImageFillSymbolLayer::estimateMaxBleed ( ) const

Returns the estimated maximum distance which the layer style will bleed outside the drawn shape.

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

Reimplemented from QgsSymbolLayerV2.

Reimplemented in QgsPointPatternFillSymbolLayer, QgsLinePatternFillSymbolLayer, and QgsRasterFillSymbolLayer.
