| AnnotationFeature | An ESRI annotation feature. |
The IAnnotationFeature interface is used for relating annotation features to other features or updating the graphic of the annotation. The Annotation property will accept any object implementing IGraphicElement. If a TextElement is used, you may reference an exiting TextSymbol stored in the SymbolCollection of the AnnotationFeatureClassExtension by using the ISymbolCollectionElement interface. It is highly recommended that you reference symbols in the SymbolCollection when storing TextElements in an annotation feature class. See the help for ISymbolCollectionElement for more details on this storage system.
The LinkedFeatureID property is used to indicate which feature the annotation is linked to for feature-linked annotation. If the feature is not linked, the property will be -1.
The AnnotationClassID property indicated which annotation class the annotation feature belogs to. An Annotation Feature Class may have have multiple Annotation Classes.
The Status property indicated whether or not the annotation feature is considered Placed or Unplaced. Unplaced annotation is not drawn by default.
After updating the either of these properties, the IFeature::Store method must be called.
The following code sample demonstrates how to update the text of an AnnotationFeature:
Public Sub UpdateText(pAnnoFeature As IAnnotationFeature2)
Dim pElement As IElement
Set pElement = pAnnoFeature.Annotation
If TypeOf pElement Is ISymbolCollectionElement Then
'use ISymbolCollectionElement for efficient annotation updates editing
Dim pSymbolCollectionElement As ISymbolCollectionElement
Set pSymbolCollectionElement = pElement
pSymbolCollectionElement.Text = "Foo"
pAnnoFeature.Annotation = pElement
Dim pFeature As IFeature
Set pFeature = pAnnoFeature
pFeature.Store
End If
End Sub
