public Matrix Transform {get;}

'Declaration
 
Public ReadOnly Property Transform As Matrix

'Usage
 
Dim instance As AnnObject
Dim value As Matrix
 
value = instance.Transform

public Matrix Transform {get;}

 get_Transform();

public:
property Matrix^ Transform {
   Matrix^ get();
}

Property Value

The current transformation System.Drawing.Drawing2D.Matrix of this AnnObject.

Each annotation object has a transformation matrix associated with it. You can perform various operations on this matrix by calling ResetTransform, Translate, Scale and Rotate.

Derived annotation objects can control the transformation operation by overriding the TransformObjectMode property.
