ClearAnnotations |
|||||||
The method ClearAnnotations (version [1]) deletes all annotations.
Version [2] deletes all annotations belonging to a particular layer (parameter Layer) and returns zero if everything is OK and -1 if the Layer parameter is invalid (valid range: 0...MAXNUMRCLAYERS). Setting Layer to 0 is equivalent to calling version [1].
