The Poly Ellipse Tool allows you to draw amorphous shapes that can be distorted, stretched and rotated. Start with an elliptical shape by positioning the mouse cursor over your picture where you want the top left side of the shape to begin. Hold down the left mouse button and drag the cursor to where you would like the opposite side. When your ellipse reaches the desired size and shape, release the mouse button.
Once you have completed your elliptical shape, the Polygon Editor will appear, allowing you to make changes to the object before it is drawn and filled.
Some examples of shapes that can be created with the Poly Ellipse Tool.
You can enable the Option Panel's Anti-alias option to smooth the edges of the shape.
