If you know, you can send an instance. Program(Pyxyu@126.com), thanks!

Vector graphics ?? How is your vector image implemented? If you want to describe a vector image, there may be several specific implementations.

If you do not know his implementation, the most stupid way is to convert it into a bitmap first, then copy and move one pixel by one according to the rule of rotation, and finally convert it back.

Who knows? Send me a copy.
