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

Reimplemented from QgsSymbolLayerV2.

Definition at line 893 of file qgsfillsymbollayerv2.cpp.

References QgsSymbolV2::color(), and mOutline.

Qt::PenStyle QgsImageFillSymbolLayer::dxfPenStyle ( ) const

Reimplemented from QgsSymbolLayerV2.

References mOutline.

double QgsImageFillSymbolLayer::dxfWidth ( const QgsDxfExport &  e,
const QgsSymbolV2RenderContext context 
) const
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, and QgsLinePatternFillSymbolLayer.
