- 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
| Visual Basic | Copy Code |

Public Sub AnnEditDesigner_MaintainAspectRatio(ByVal editDesigner As AnnRectangleEditDesigner) editDesigner.MaintainAspectRatio = Not editDesigner.MaintainAspectRatio End Sub | |
| C# | Copy Code |

public void AnnEditDesigner_MaintainAspectRatio(AnnRectangleEditDesigner editDesigner) { editDesigner.MaintainAspectRatio = !editDesigner.MaintainAspectRatio; } | |
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.
