You can display resize handles on edges or corners. Use the following keywords to set up the handles property: top, bottom, left, and right. If you specify two adjacent sides (for example, "bottom right"), the control displays a handle in the corner.
The keepAspectRatio property specifies whether a corner handle resizes content proportionally. Set this property to false to allow free-form resize operations.
