Примеры
This C# example returns an interpolated point from a Stroke object, theStroke, given as a floating point (Float) index value.
private Point LocatePoint(Stroke theStroke, float theFIndex)
{
Point ptResult = theStroke.GetPoint((int)theFIndex);
float theFraction = theFIndex - (int)theFIndex;
if (theFraction > 0.0f)
{
Point ptDelta = theStroke.GetPoint((int)theFIndex + 1);
ptResult.X += (int)((ptDelta.X - ptResult.X) * theFraction);
ptResult.Y += (int)((ptDelta.Y - ptResult.Y) * theFraction);
}
return ptResult;

This Microsoft Visual Basic .NET example returns an interpolated point from a Stroke object, theStroke, given as a floating point (Float) index value.
Private Function LocatePoint( _
ByVal theStroke As Stroke, ByVal theFIndex As Single) As Point
Dim theIndex As Integer = Math.Floor(theFIndex)
Dim theFraction As Single = theFIndex - theIndex
Dim ptResult As Point = theStroke.GetPoint(theIndex)
If theFraction > 0.0 Then
Dim ptDelta As Point = theStroke.GetPoint(theIndex + 1)
ptResult.X += CInt((ptDelta.X - ptResult.X) * theFraction)
ptResult.Y += CInt((ptDelta.Y - ptResult.Y) * theFraction)
End If
Return ptResult
