Detailed Description

GeoLayerManager - Manages setup and rendering of all geographical data layers, including map layers.

Member Function Documentation

◆ drawBitmap()

std::shared_ptr< STK::Image > Maria::GeoLayerManager::drawBitmap	(	const std::shared_ptr< RasterProjector > &	viewport,
		double	mapScale,
		int	numSamples = `0`
	)

Draw current layers to a bitmap. Must be called on GL thread. If prepareBitmap returned 0, this will not wait, otherwise it will call prepareBitmap until it is ready or times out.

◆ drawFrame()

void GeoLayerManager::drawFrame ( )

Redraw map in viewport.

◆ getDebugRendering()

bool Maria::GeoLayerManager::getDebugRendering ( const std::string & feature ) const

Check if debug rendering feature is enabled.

Parameters

feature Which debug rendering feature to query. Currently allowed values are: "tiles", "tilelabels", "maplabels"

Returns

◆ prepareBitmap()

int Maria::GeoLayerManager::prepareBitmap	(	const std::shared_ptr< RasterProjector > &	viewport,
		double	mapScale
	)

Prepare for drawing to bitmap. Returns number of tiles or other resources that needs to be loaded for bitmap rendering to be complete. Call repeatedly until it returns 0 when ready to draw, or -1 if there is nothing to draw/error condition.

◆ removeLayer()

void Maria::GeoLayerManager::removeLayer ( const std::string & layerId )

inline

Remove layer This will remove the given layer id from the layers list.

◆ setDebugRendering()

void Maria::GeoLayerManager::setDebugRendering	(	const std::string &	feature,
		bool	enabled
	)

Control debug rendering feature.

Parameters

feature	Which debug rendering feature to enable. Currently allowed values are: "tiles", "tilelabels", "maplabels"
enabled	true to enable feature, false to disable.

◆ setMapResolutionScale()

void Maria::GeoLayerManager::setMapResolutionScale ( double scale )

inline

Set resolution scale factor. This scale factor will be multiplied with the base pixel scale and can be used to temporarily increase or decrease the pixel resolution of the map. The scale factor affects the pixel error tolerance of the display so that higher numbers means lower resolution. It also affects the template layer scale selections.

Parameters

scale scale by this much

◆ setPixelTolerance()

void Maria::GeoLayerManager::setPixelTolerance ( double pixelTolerance )

inline

Resolution parameter 1.0 guarantees that the pixels are at least the same resolution as the viewport resolution. 2.0 allows the pixels to be up to 2x as big as the viewport resolution.

Parameters

pixelTolerance

◆ setViewport()

void Maria::GeoLayerManager::setViewport ( const std::shared_ptr< Maria::Viewport > & vp )

inline

Update the geographical viewport.
