Converting labels to geodatabase annotation for an entire map


About converting labels to geodatabase annotation for an entire map

This topic shows how to use the ConvertLabelsToAnnotation class to change labels for an entire map to a geodatabase annotation. The ConvertLabelsToAnnotation class is a coarse-grained object that encapsulates the logic needed to perform this conversion. This class works with maps labeled with Maplex or the standard label engine.
The following code examples contain a Boolean option for making the annotation feature linked. Feature-linked annotation can only be created with an ArcGIS Desktop Standard or Advanced license level.
The map reference passed into the function must be activated on a window. Check the IsMapActivated property on IActiveView to determine if the map is activated. Typically, the map is activated unless it's opened via MapDocument or MapReader.
