Places markers in a polygon.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
MarkerPlacementInsidePolygon places markers inside a polygon geometry. Markers are placed using X and Y steps, X and Y offsets, along polygon grid angle, with shifts in odd rows using a polygon clipping method.
Interfaces
| Interfaces | Description |
|---|---|
| IClippingMethod | Provides access to the clipping method required by an object. |
| IDocumentVersionSupportGEN (esriSystem) | Provides access to extend the IObjectStream interface with methods to hande saving objects that did not exist in previous versions of the software. |
| IEditInteraction | Provides access to methods declaring how graphic attributes interact with a representation tool. |
| IGraphicAttributes | Provides access to members that control the graphic attributes. |
| IGraphicAttributes2 | Provides access to members that control the graphic attributes. |
| IMarkerPlacement | Provides access to members that control the marker placement. |
| 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) |
