The Editable Rectangle Tool allows you to draw a rectangle that can be distorted, stretched and rotated. As with the Standard Rectangle, position the mouse cursor over your picture where you want the top left corner of the shape to begin. Hold down the left mouse button and drag the cursor to where you would like the opposite corner. When your rectangle reaches the desired size and shape, release the mouse button.
Once you have completed your rectangle, the Polygon Editor will appear, allowing you to make changes to the object before it is drawn and filled.
You can enable the Option Panel's Anti-alias option to smooth the edges of the shape.
