Classes that implement ISymbolCollection

Classes Description
SymbolCollection Collection of symbols and id pairs.


ISymbolCollection provides access to the members of the symbol collection.  This interface is most commonly used to maintain the symbol collection of an AnnotationFeatureClassExtension.  Care should be taken when modifying symbols in the collection of an AnnotationFeatureClassExtension.  Updating a TextSymbol property for an existing symbol in use that results in a change in the size or shape of a TextElement will result in a disconnect between the drawn symbol and the feature geometry.  This can be resolved by updating the out of sync features by calling IFeature::Store, but it is generally recommended that only new symbols should be added.  ISymbolCollection2 provides new methods for adding new symbols to the collection and guaranteeing unique symbol IDs.  It is recommended that developers use ISymbolCollection2 to interact with the SymbolCollection.
