Description
GeometricEffectDonut is a geometric effect that creates a donut effect on polygon geometries.
Interfaces
| Interfaces | Description |
|---|---|
| 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. |
| IGeometricEffect | Provides access to the Geometric Effect Interface. |
| IGraphicAttributes | Provides access to members that control the graphic attributes. |
| IGraphicAttributes2 | Provides access to members that control the graphic attributes. |
| 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) |
Remarks
Graphic attributes defining this object are listed in the following enumeration esriGeometricEffectAttributes.
Geometric Effect is a dynamic process that alters the geometry of feature representations. Effects can be added to either a basic symbol layer or at a representation rule level making it globally applicable to all symbol layers present for that rule to create complex symbols.
This geometric effect can be managed by one of the following graphic attributes:
- esriGADonutWidth - esriAttributeTypeSize
- esriGADonutSimple - esriAttributeTypeBoolean
- esriGADonutMethod - esriAttributeTypeEnum
Width is the thickness of the donut from the outside to the inside. For example, if width = 0 then the thickness of the donut is 0 and resulting geometry will have zero area.
The Donut method can be selected from one of the following options:
- MITERED - 0
- BEVELLED - 1
- ROUNDED - 2
- TRUE_BUFFER - 3
