RepresentationRule Class (ArcObjects .NET 10.8 SDK)
|
This document is archived and information here might be outdated. Recommended version. |
An object defining a representation rule.
RepresentationRule object is a collection of basic symbols such as BasicLineSymbol, BasicFillSymbol and BasicMarkerSymbol along with MarkerPlacement used for representing features within a representationclass. Complex symbols can be created by incorporating one or more geometric effects into your rule.
Standard ArcGIS symbols such as SimpleMarkerSymbol, SimpleLineSymbol etc implementing ISymbol interface can also be converted to a representation rule using IRepresentationRuleInit interface. When a standard ArcGIS symbol is converted to a representation rule, it may contain either one or more basic symbol layers.
The graphic attributes present for a rule can be overriden using regular attribute fields.
Use IRepresentationRule interface to manage the individual symbol layer within a rule.
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.
