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
End Function
