Usage

From source file:ShapeTransform.java

/**
 * Clips the given shape to the given bounds. If the shape is a Line2D, manual
 * clipping is performed, as the built in Area does not handle lines.
 * /*from ww  w.  j av  a2 s. com*/
 * @param s
 *          the shape to be clipped
 * @param bounds
 *          the bounds to which the shape should be clipped
 * @return the clipped shape.
