MaintainAspectRatio Property (AnnEditDesigner)

Summary

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

Syntax

C++

public bool MaintainAspectRatio {get; set;}

Public Property MaintainAspectRatio As Boolean

public: 
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, 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.
