        public PointArrayPixellator​(java.awt.Point[] points)
        Constructor.
        Parameters:
        points - array of points to iterate over

    • Method Detail

      • getBounds

        public java.awt.Rectangle getBounds()
        Description copied from interface: Pixellator
        Returns a copy of the bounding rectangle for this pixellator. All points iterated over by this object will fall within this rectangle. If this object has no points, null may be returned.
        Specified by:
        getBounds in interface Pixellator
        Returns:
        bounds

      • start

        public void start()
        Description copied from interface: Pixellator
        Makes this object ready to iterate. Should be called before any call to Pixellator.next().
        Specified by:
        start in interface Pixellator

      • next

        public boolean next()
        Description copied from interface: Pixellator
        Moves to the next point in the sequence. Must be called before any call to Pixellator.getX()/Pixellator.getY(). Returns value indicates whether there is a next point.
        Specified by:
        next in interface Pixellator
        Returns:
        next true iff there are more points

      • getX

        public int getX()
        Description copied from interface: Pixellator
        Returns the X value for the current point.
        Specified by:
        getX in interface Pixellator
        Returns:
        x

      • getY

        public int getY()
        Description copied from interface: Pixellator
        Returns the Y value for the current point.
        Specified by:
        getY in interface Pixellator
        Returns:
        y
