上面导出PDF和EXCEL的问题是图片路径出错！！！

数据库中存存的图片路径是"../dishpic/722f464f-3883-42aa-901f-21706da9c582.png",浏览器上能够显示，但在导出PDF和EXCEL时路径就不对了。

IReport设计出来使用图片控件；使用的是相对路径。

我在判断程序如果是导出excel或是pdf时我就从新做了个模板，将上面的属性“Is Lazy”属性给取消掉，使用的路径就是绝对路径，这样就能够正常导出Excel了。

但是我又遇到问题啦！！！！

导出下面格式的内容就不报错。

但是导出下面的格式内容就有问题！！

我现在想即便这里有空白，我也能导出内容，只是有空白的导不出内容就是了，希望有懂的给予指导。感谢了
