| + | ====Syntax of fillellipse ==== | ||

| + | ==== Description of fillellipse ==== | ||
| + | <code c> | ||
| + | Draws an ellipse using (x,y) as a center point and xradius and yradius as | ||
| + | the horizontal and vertical axes, and fills it with the current fill | ||
| + | color and fill pattern. | ||
