AfterDrawing()

void osmscout::MapPainterGDI::AfterDrawing ( const StyleConfig & styleConfig, const Projection & projection, const MapParameter & parameter, const MapData & data )

overrideprotectedvirtual

Reimplemented from osmscout::MapPainter.

AfterPreprocessing()

void osmscout::MapPainterGDI::AfterPreprocessing ( const StyleConfig & styleConfig, const Projection & projection, const MapParameter & parameter, const MapData & data )

overrideprotectedvirtual

Low level drawing routines that have to be implemented by the concrete drawing engine. Some optional callbacks between individual processing steps.

Reimplemented from osmscout::MapPainter.

BeforeDrawing()

void osmscout::MapPainterGDI::BeforeDrawing ( const StyleConfig & styleConfig, const Projection & projection, const MapParameter & parameter, const MapData & data )

overrideprotectedvirtual

Reimplemented from osmscout::MapPainter.

DrawArea()

void osmscout::MapPainterGDI::DrawArea ( const Projection & projection, const MapParameter & parameter, const AreaData & area )

overrideprotectedvirtual

Draw the given area using the given FillStyle for the area outline.

Implements osmscout::MapPainter.

DrawContourSymbol()

void osmscout::MapPainterGDI::DrawContourSymbol ( const Projection & projection, const MapParameter & parameter, const Symbol & symbol, const ContourSymbolData & data )

overrideprotectedvirtual

overrideprotectedvirtual

(Optionally) fills the area with the given default color for ground. In 2D backends this just fills the given area, 3D backends might draw a sphere or an infinite plane.

Implements osmscout::MapPainter.

DrawIcon()

void osmscout::MapPainterGDI::DrawIcon ( const IconStyle * style, 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.

DrawLabels()
