Example 16 with Arc2D

use of java.awt.geom.Arc2D in project poi by apache.

the class SLGraphics method drawArc.

/**
     * Draws the outline of a circular or elliptical arc
     * covering the specified rectangle.
     * <p>
     * The resulting arc begins at <code>startAngle</code> and extends
     * for <code>arcAngle</code> degrees, using the current color.
     * Angles are interpreted such that 0&nbsp;degrees
     * is at the 3&nbsp;o'clock position.
     * A positive value indicates a counter-clockwise rotation
     * while a negative value indicates a clockwise rotation.
     * <p>
     * The center of the arc is the center of the rectangle whose origin
     * is (<i>x</i>,&nbsp;<i>y</i>) and whose size is specified by the
     * <code>width</code> and <code>height</code> arguments.
     * <p>
     * The resulting arc covers an area
     * <code>width&nbsp;+&nbsp;1</code> pixels wide
     * by <code>height&nbsp;+&nbsp;1</code> pixels tall.
     * <p>
     * The angles are specified relative to the non-square extents of
     * the bounding rectangle such that 45 degrees always falls on the
     * line from the center of the ellipse to the upper right corner of
     * the bounding rectangle. As a result, if the bounding rectangle is
     * noticeably longer in one axis than the other, the angles to the
     * start and end of the arc segment will be skewed farther along the
     * longer axis of the bounds.
     * @param        x the <i>x</i> coordinate of the
     *                    upper-left corner of the arc to be drawn.
     * @param        y the <i>y</i>  coordinate of the
     *                    upper-left corner of the arc to be drawn.
     * @param        width the width of the arc to be drawn.
     * @param        height the height of the arc to be drawn.
     * @param        startAngle the beginning angle.
     * @param        arcAngle the angular extent of the arc,
     *                    relative to the start angle.
     * @see         java.awt.Graphics#fillArc
