IRasterFunction2 Interface

Provides access to members that control a raster function.

Members

	Name	Description
	ClearCache	Clear the cache.
	ComputeFootprint	Computes the footprint.
	ComputeFootprintAndCenter	Computes the footprint and center.
	GetFiles	Gets source files within a given clipping geometry.
	InvalidDatasetProperties	The properties to be invalidated when a function raster dataset is initialized.
	IsActive	Indicates if the function is actively participating in the chain.
	IsCacheStale	Indicates if the raster cache is stale and needs to be refreshed.
	ProcessingCost
	RefreshCache	Refresh raster cache.
