Example 11 with Arc2D

use of java.awt.geom.Arc2D in project platform_frameworks_base by android.

the class Path_Delegate method arcTo.

     * start of the arc. However, if the path is empty, then we call moveTo()
     * with the first point of the arc. The sweep angle is tread mod 360.

Example 12 with Arc2D

use of java.awt.geom.Arc2D in project scriptographer by scriptographer.

the class AbstractGraphics2D method drawArc.

/**
     * Draws the outline of a circular or elliptical arc
     * covering the specified rectangle.

     * 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.
