Basic marker symbol object.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
The BasicMarkerSymbol is used to create a basic marker symbol and is comprised of a MarkerPlacement.
Extended Error Information
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
Interfaces
| Interfaces | Description |
|---|---|
| IBasicMarkerSymbol | Provides access to properties of the basic marker symbol. |
| IBasicSymbol | Provides access to methods that control the basic symbol. |
| 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. |
| IDrawingOutline | Provides access to methods dealing with the outline of a drawing rule. |
| IGeometricEffect | Provides access to the Geometric Effect Interface. |
| IGeometricEffects | Provides access to members that control the geometric effect list. |
| IGraphicAttributes | Provides access to members that control the graphic attributes. |
| IGraphicAttributes2 | Provides access to members that control the graphic attributes. |
| IMapLevel | Provides access to members that control the map level. |
| 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) | |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
| IXMLSerialize (esriSystem) | Provides access to members that XML serialize and deserialize an object to/from XML. |
| IXMLVersionSupport (esriSystem) | Provides access to members that help in serializing an object to different namespaces (versions). |
Remarks
Use IMarkerPlacement interface along with IGraphicAttributes interface to define a new marker placement and assign it a basic marker symbol.
