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.
