public class GeometricEffectOffset
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, IGeometricEffect, IGraphicAttributes, IGraphicAttributes2, IEditInteraction, IPersist, IPersistStream, IDocumentVersionSupportGEN, Externalizable

Offsets a line by a specified distance.

Description

GeometricEffectOffset is a geometric effect that offsets either line or polygon geometries by a given distance.

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:

• esriGAOffsetCurveOffset - esriAttributeTypeSize
• esriGAOffsetCurveMethod - esriAttributeTypeEnum
• esriGAOffsetCurveOption - esriAttributeTypeEnum
• esriGAOffsetCurveCount - esriAttributeTypeInteger

The offset curve method can be selected from one of the following options:

• MITERED - 0
• BEVELLED - 1
• ROUNDED - 2
• SQUARE - 3

The offset curve option can be selected from one of the following options:

• OPTION_FAST - 0
• OPTION_ACCURATE - 1

Remarks

Use IsSupportedAtVersion to identify if a particular object should be saved to the ObjectStream. This result is based on the esriArcGISVersion enumeration. In some instances, if the object is not supported at a particular ArcGIS version, the object may support conversion to another similar object; use IDocumentVersionSupportGEN::ConvertToSupportedObject to accomplish this.

Remarks

This method should be used when IDocumentVersionSupportGEN::IsSupportedAtVersion returns FALSE. Calling ConvertToSupportedObject will return an IUnknown pointer to a relevant object supported at the particular ArcGIS version.
