Interfaces

Interfaces	Description
IDataExclusion	Provides access to members that control the exclusion of data values from a renderer.
IDataExclusion2	Provides access to members that control the exclusion of data values from a renderer.
IDotDensityRenderer	Provides access to members that control the drawing of varying densities of dots within polygon features to represent different quantities.
IDotDensityRenderer2	Provides access to members that control the drawing of varying densities of dots within polygon features to represent different quantities.
IDotDensityUIRenderer	Provides access to members that work with additional renderer properties which appear on the user interface.
IExportSupport	Provides access to export support members.
IFeatureRenderer	Provides access to members that control functionality common to all feature renderers.
ILegendInfo	Provides access to members that control legend information provided by a renderer.
IPersist	Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile.
IPersistStream (esriSystem)
IRendererFields	Provides access to members that work with the list of fields for renderers that use multiple value fields.
