Syntax

C#
Visual Basic
Objective-C
Java
C++

public bool MaintainAspectRatio {get; set;}

'Declaration
 
Public Property MaintainAspectRatio As Boolean

'Usage
 
Dim instance As AnnEditDesigner
Dim value As Boolean
 
instance.MaintainAspectRatio = value
 
value = instance.MaintainAspectRatio

public:
property bool MaintainAspectRatio {
   bool get();
   void set (    bool value);
}

Property Value

true to maintain the aspect ratio; otherwise, false.

Remarks

When selecting an AnnRectangleObject, or any annotation object that derives from AnnRectangleObject, eight control points appear. If MaintainAspectRatio is true (default), dragging one of the four corner control points will change the size of the annotation object while maintaining its aspect ratio. If false, the aspect ratio is not preserved.

Example

This example toggles the MaintainAspectRatio state of the AnnRectangleEditDesigner. To see the effect of this example, perform the following actions:

Select a rectangular AnnObject
Run the example
Drag one of the corner control points
Run the example again
Drag one of the corner control points
