Sets the existing elements of an existing safe array to be equal to the four control points of this bezier curve.

Parameters:

controlPoints - A reference to a com.esri.arcgis.geometry.IPoint array (in)

Sets this Bezier curve's control points from an array of between 1 to 4 input points.

Description

Defines the control points of the bezier curve using an array of four Points. If the array is defined as an array from 0 to 3, then the index of each point corresponds to the control point they represent.

Remarks

Use PutCoord to set a single control point.

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

Copies the specified control point of this Bezier curve into the input point.

Parameters:

Sets the specified (0 <= index < 4) control point of this Bezier curve.

Parameters:

index - The index (in)

controlPoint - A reference to a com.esri.arcgis.geometry.IPoint (in)

Throws:
