POI 在Word中添加图章--浮于文字或在文字下方的图片（文字环绕）

1、添加依赖

	     org.apache.poi
	     poi-ooxml
	     3.15


	    org.apache.poi
	    poi-scratchpad
	    3.15

2、工具类

     * tString abText, 在Word中盖图章的标识字符串，如：(签字/盖章)
     * int width, 图章宽度
     * int height, 图章高度

     * int topOffset, 图章在编辑段落向上偏移量
     * boolean behind，图章是否在文字下面
    * @return void
