		const Vertex2D &	centerPos,
		double	width,
		double	height )

overrideprotectedvirtual

Draw the Icon as defined by the IconStyle at the given pixel coordinate (icon center).

Implements osmscout::MapPainter.

		LineStyle::CapStyle	startCap,
		LineStyle::CapStyle	endCap,
		const CoordBufferRange &	coordRange )

overrideprotectedvirtual

Draw simple line with the given style,the given color, the given width and the given untransformed nodes.

Implements osmscout::MapPainter.

		const Vertex2D &	screenPos,
		double	scaleFactor )

overrideprotectedvirtual

Draw the Symbol as defined by the SymbolStyle at the given pixel coordinate (symbol center).

Implements osmscout::MapPainter.

◆ GetFontHeight()

double osmscout::MapPainterQt::GetFontHeight	(	const Projection &	projection,

		const Projection &	projection,
		const MapParameter &	parameter,
		IconStyle &	style )

overrideprotectedvirtual
