PROCEDURE SetPolyPt(
				objectHd : HANDLE;
				index    : INTEGER;
				xR       : REAL;
				yR       : REAL);
def vs.SetPolyPt(objectHd, index, xR, yR):
    return None

Parameters

Name Type Description
objectHd HANDLE Handle to polygon.
index INTEGER Index of vertex.
xR REAL New X coordinate of vertex.
yR REAL New Y coordinate of vertex.

Remarks

(Gerard Jonker, 2007 Jan. 8) Please have a look at my [http://www.vectorlab.info/index.php?title=Absolute_Origin comments on the VectorLab] regarding this function, concerning index and origin.

(_c_, 2010 Dec. 25) From Raymond Mullin: ''It only works for Polygons, and not for Polylines.''. Using this function on polylines will rise an invalid handle warning. Please be careful on conversions from polygon to polyline through InsertVertex or other routines. See SetPolylineVertex. I thus remove the word ''polylines'' from the description above.
