Question

java利用jacob实现word文档水印操作

现已实现了jacob对word文件文字水印的添加，问题是水印是重复添加，如果原先文件中已添水印，会在文档某角落存在。想要效果：新水印添加时，替换掉原来水印，即只存在一个水印。
问题已解决。
//查看word的开发者工具，使用shapeRange的Delete方法，可删除旧水印
Dispatch shapeRange_old = Dispatch.call(shapes, "Range",new Variant(1)).toDispatch();
Dispatch.call(shapeRange_old,"Delete");
