clipRect() virtual bool GiCanvas::clipRect ( float  x, float  y, float  w, float  h  ) pure virtual Intersect the current clipping path with `rect'. Note that this function resets the context's path to the empty path. 返回 true if successful and the result clipping path isn't empty. 参见 saveClip, restoreClip 在 GiGdipCanvas, GiShapeAdapter, GiCanvasAdapter, GiRecordCanvas , 以及 GiSvgCanvas 内被实现. 这是这个函数的调用关系图:
