Basic fill symbol object.
Product Availability
Description
The BasicFillSymbol is used to create a basic fill symbol comprised of a FillPattern.
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 |
|---|---|
| IBasicFillSymbol | Provides access to properties of the basic fill 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. |
| 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 IFillPattern interface along with IGraphicAttributes interface to define a new fill pattern and assign it a basic fill symbol.
There are 3 different types of Fill Patterns available for defining a basic fill symbol: GradientPattern, LinePattern and SolidColorPattern.
A SolidColorPattern has the following GraphicAttributes:
- Color - esriAttributeTypeColor
A LinePattern has the following GraphicAttributes:
- Color - esriAttributeTypeColor
- Width - esriAttributeTypeSize
- Angle - esriAttributeTypeDouble
- Step - esriAttributeTypeSize
- Offset - esriAttributeTypeSize
A Gradient has the following GraphicAttributes:
- Color1 - esriAttributeTypeColor
- Color2 - esriAttributeTypeColor
- Algorithm - esriAttributeTypeEnum
- Style - esriAttributeTypeEnum
- Intervals - esriAttributeTypeInteger
- Percentage - esriAttributeTypeDouble
- Angle - esriAttributeTypeDouble
