RasterizingLayer() public method

Creates a RasterizingLayer which rasterizes a layer for performance

public RasterizingLayer ( ILayer layer, int delayBeforeRasterize = 500, double renderResolutionMultiplier = 1, IRenderer rasterizer = null, double overscanRatio = 1, bool onlyRerasterizeIfOutsideOverscan = false ) : System
layer	ILayer	The Layer to be rasterized
delayBeforeRasterize	int	Delay after viewport change to start rerasterising
renderResolutionMultiplier	double
rasterizer	IRenderer	Rasterizer to use. null will use the default
overscanRatio	double	The ratio of the size of the rasterized output to the current viewport
onlyRerasterizeIfOutsideOverscan	bool	/// Set the rerasterization policy. false will trigger a Rerasterisation on /// every viewport change. true will trigger a Rerasterisation only if the viewport moves outside the existing /// rasterisation. ///
return	System
