Example 1 with Ellipse2D

use of java.awt.geom.Ellipse2D in project scriptographer by scriptographer.

the class AbstractGraphics2D method drawOval.

/**
     * Draws the outline of an oval.

     * <p>
     * The oval covers an area that is
     * <code>width&nbsp;+&nbsp;1</code> pixels wide
     * and <code>height&nbsp;+&nbsp;1</code> pixels tall.
     * @param       x the <i>x</i> coordinate of the upper left
     *                     corner of the oval to be drawn.
