Public Sub ExpandM ( _
    ByVal dm As Double, _
    ByVal asRatio As Boolean _
)
[C#]
public void ExpandM (
    double dm,
    bool asRatio
);
[C++]
HRESULT ExpandM(
  double dm,
  VARIANT_BOOL asRatio
);
[C++]

Parameters dm dm is a parameter of type double asRatio asRatio is a parameter of type VARIANT_BOOL

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Description

ExpandM scales the M attributes of the Envelope.  If asRatio=FALSE, the scaling is additive (MMin=MMin - dm, MMax=MMax + dm).  If asRatio=TRUE, the scaling is multiplicative (MMin=MMin - dm*(MMax - MMin)/2, MMax=MMax + dm*(MMax - MMin)/2).
