MaintainAspectRatio Property

Summary

Gets or sets a value that indicates whether to preserve the aspect ratio when moving a corner control point.

Syntax

C++

public virtual bool MaintainAspectRatio { get; set; }

  
Public Overridable Property MaintainAspectRatio As Boolean

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

Property Value

true to maintain the aspect ratio; otherwise, false.

Remarks

When selecting an AnnRectangleObject, or any annotation object that derives from AnnRectangleObject, or an AnnGroupObject, 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. For more information, refer to New Annotation Features of Version 14.5 (Deprecated).

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
