double QgsImageFillSymbolLayer::estimateMaxBleed ( ) const
overridevirtual

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.
