LEADTOOLS Annotations (Leadtools.Annotations assembly)

Transform Property (AnnObject)

Show in webframe
Example 





Returns the current transformation System.Drawing.Drawing2D.Matrix of this AnnObject.
Syntax
public Matrix Transform {get;}
'Declaration
 
Public ReadOnly Property Transform As Matrix
'Usage
 
Dim instance As AnnObject
Dim value As Matrix
 
value = instance.Transform

            

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

Property Value

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

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.
