DrawMap()

void osmscout::MapPainterOpenGL::DrawMap

(

)

OpenGL draw call. Draws all feature of the map to the context.

GetCenter()

osmscout::GeoCoord osmscout::MapPainterOpenGL::GetCenter

(

)

Returns the visual center of the map.

OnTranslation()

void osmscout::MapPainterOpenGL::OnTranslation	(	int	startPointX,
		int	startPointY,
		int	endPointX,
		int	endPointY
	)

Translates the map to the given direction.

OnZoom()

void osmscout::MapPainterOpenGL::OnZoom

(

float

zoomDirection

)

Zooms on the map.

ProcessData()

void osmscout::MapPainterOpenGL::ProcessData	(	const osmscout::MapData &	data,
		const osmscout::MapParameter &	parameter,
		const osmscout::Projection &	projection,
		const osmscout::StyleConfigRef &	styleConfig
	)

Processes all OSM data, and converts to the format required by the OpenGL pipeline.

SwapData()

void osmscout::MapPainterOpenGL::SwapData

(

)

Swaps currently drawn data and processed data.
