Description

Use the QueryBoundary method to find the shape of a callout. This method populates a Polygon with the boundary of the callout. For a LineCallout, this is the minimum bounding rectangle of the leader line and text background box. For a BalloonCallout, this is the shape of the balloon. For a MarkerTextBackground, this is the union of the bounding box of the Marker and the Text.
