                                       float[] pts)

      • deltaTransformPoint

        public static void deltaTransformPoint​(java.awt.geom.AffineTransform transform,
                                       java.awt.geom.Point2D pt)

      • inverseTransformRect

        public static void inverseTransformRect​(java.awt.geom.AffineTransform transform,
                                        java.awt.geom.Rectangle2D rect)
        Transform a rectangle in device space to user space. The rectangle is modified. The coordinates of the result are normalized (lower left corner has smallest coordinate values).
        Parameters:
        transform - The transformation from user space to device space.
        rect - The rectangle whose coordinates are transformed, the rectangle is modified.

      • normalizeRect

        public static void normalizeRect​(float[] pts)

      • normalizeRect

        public static void normalizeRect​(java.awt.geom.Rectangle2D rect)
        Normalize the rectangle. The x and y value of the rectangle are updated to have the smallest coordinates (lower left corner).
        Parameters:
        rect - The rectangle whose coordinates are normalized, the rectangle is modified.
