Resizing a drawing object
The same considerations for resizing an image apply also to resizing an object. Select the object, click on one of the eight handles around it and drag it to its new position. For a scaled resizing, select one of the corner handles and keep the Shift key pressed while dragging the handle to its new position.
For more sophisticated control of the size of the object, select Format > Object > Position and Size from the menu bar. Use the Position and Size dialog box 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.
