    In This Topic
    Sets the Ms at the beginning and the end of the geometry and interpolates the M-values between these values.

       Multipart multipart,
       double fromM,
       double toM
    Public Function SetAndInterpolateMsBetween( _
       ByVal multipart As Multipart, _
       ByVal fromM As Double, _
       ByVal toM As Double _
    ) As Multipart


    The multipart on which to set the M-values.
    The beginning M-value.
    The end M-value.

    Return Value

    The multipart with new M-values. If the input multipart is empty, then it is returned unchanged.
    Multipart is null.
    This geometry is not M-Aware.
    The input fromM and toM are invalid and M-values cannot be interpolated.
    Spatial reference of multipartis an image coordinate system.
