如何在Birt报告中添加外部阴影图像

Question

我有一个报告，其中我根据列值显示图像（动态图像名称），如何设置阴影图像，如果数据库中的图像为空，则在位于资源的birt报告中显示阴影图像

Answer 1

What you can do is to have two images and manage their visibility based on the value of column. ie if there is null in database then set visibility of shadow image is true and other one is false.
This is how you can set visibility of particular widget.
