Group Container _VML Related

The use of group is simple, but the function is very powerful. It allows a series of VML objects to use a common coordinate system, which is often used, basically if a page that uses more than one VML object uses group. The benefit of using group is that you can dynamically change the coordsize value to magnify or shrink the VML across the group.











Believe that if you understand the above code, the Group must understand. It uses a Rect of the same size as group, and then adds shadow rendering. Use an interesting example of MSDN to look at the important usage of Group: (Change the value of the scroll bar, the picture on the right rotates accordingly)



In this example, the image is completely drawn from VML, and dynamically changing the group's Rotation property allows for the rotation of the object within the group.
