Changes this arc into its complement; 'from' and 'to' points are unchanged.
[Visual Basic .NET]
Public Sub Complement ( _
)
[C#] public void Complement ( );
[C++]
HRESULT Complement(
void
);
The Complement of a CircularArc is the CircularArc between the ToPoint and the FromPoint of the original CircularArc that creates a full circle when combined with the original CircularArc. The Complement maintains the same FromPoint and ToPoint as the original CircularArc, but has the different IsMinor and IsCounterClockwise values.
//This example shows how to create a Complement of Circular arc.
static void ComplementArcs()
{
//Create three points to draw an arc through.
IPoint point1=new ESRI.ArcGIS.Geometry.Point();
IPoint point2=new ESRI.ArcGIS.Geometry.Point();
IPoint point3=new ESRI.ArcGIS.Geometry.Point();
point1.PutCoords(200, 200);
point2.PutCoords(200, 300);
point3.PutCoords(300, 300);
//Construct a Three Point Arc and draw as solid line.
IConstructCircularArc constructionArc=new CircularArc() as IConstructCircularArc;
constructionArc.ConstructThreePoints(point1, point2, point3, true);
//Draw the compliment of the previous arc as dashed line.
ICircularArc evilCircularArc=constructionArc as ICircularArc;
evilCircularArc.Complement();
}
