Resizing a drawing object
Select the object, click on one of the eight handles around it and drag it to its new size. For a scaled resizing, select one of the corner handles and keep the Shift key pressed while dragging the handle.
For more control of the size of the object, use the Position and Size dialog (see “Position and Size”) to set the width and height independently. If the Keep ratio option is selected, then the two dimensions change so that the proportion is maintained, allowing for a scaled resizing.
