◆ cleanupCaches()

void Maria::GeoLayer::cleanupCaches ( bool keepCurrentFrame )

virtual

This method is called at regular intervals to clean up cached data, such as OpenGL textures, graphics buffers etc. Only data that can be reproduced automatically should be cleaned up by this method.

Parameters

keepCurrentFrame Keep data that are necessary for the current frame (if applicable).

◆ needsRedraw()

bool Maria::GeoLayer::needsRedraw ( ) const

virtual

Check if a layer requires a redraw on next frame. This will typically be due to changed content, newly loaded data, etc.

Returns

Reimplemented in Maria::DrawLayer, Maria::ElevationAnalysisLayer, Maria::GeoBitmapLayer, and Maria::MapLayer.

◆ update()

bool Maria::GeoLayer::update	(	const std::shared_ptr< RasterProjector > &	viewport,
		double	scale,
		float	pixelScale,
		bool	sync
	)

virtual

Update layer for rendering. This method should determine if there is anything to render in the layer, and prepare the layer for rendering. This includes for example visibility testing, loading of data, generating graphics structures, etc.

Parameters

viewport
scale	Map scale for the current view.
pixelScale	Scale factor for the pixel allowed pixel size.
sync	Synchronous loading of data. This will be true in settings where we need all data to be loaded synchronously, for example when rendering to a bitmap.

Returns: True if the layer should be rendered, false if not.

Reimplemented in Maria::ElevationAnalysisLayer, Maria::GridLayer, Maria::MapLayer, and Maria::RadioNetworksLayer.
