rotatepath (Number angle) typedict.Path
 
Changes this path by applying a rotation of angle degrees (clockwise when angle is positive) to every point currently stored in this path, and returns this path to the caller. We can talk about clockwise or counterclockwise rotations because the coordinates of the points in a path are always assumed to be stored in device space, which closely matches the device-dependent coordinate system that Java assigns to your screen.
 
 Example:   The program,
import yoix.*.*;

Path p1;
Path p2;

p1 {        // "named block"
    moveto(0, 0);
    rlineto(72, 0);
    rlineto(0, 36);
    closepath();
    rmoveto(72, 36);
}

p2 {        // "named block"
    moveto(0, 0);
    rlineto(72, -36);
}

JFrame f = {
    Color background = Color.white;

    paint(Rectangle r) {
        graphics {        // "named block"
            moveto(72, 72);
            appendpath(p1);
            appendpath(p2);
            appendpath(p1);
            rotatepath(15);
            gsave();
            setrgbcolor(0, 0, 1);
            fill();
            grestore();
            setrgbcolor(1, 0, 0);
            stroke();
        }
    }
};

f.visible = TRUE;
defines a paint function in a frame that fills and strokes a path that is built from two separate paths using appendpath and rotatepath.
 
 Return:   Path
