推荐答案

我不会为您提供完整的代码-我没有时间实施整个测试过程，因为我做了这样的事情已经有一段时间了.我不想敲一个不起作用的例子...:笑:

但是，这实际上非常简单-您所需要做的就是在Paint事件中，将适当的转换应用于提供的Graphics对象. MSDN应该通过一些玩法向您展示如何: Graphics.RotateTransform [^ ]和 Graphics.ScaleTransform [

I''m not going to give you the entire code - I don''t have time to implement the whole thing for testing, and it''s been a while since I did anything like this. I don''t want to bang out an example that doesn''t work...:laugh:

However, it''s actually pretty simple - all you need to do is in your Paint event, apply the appropriate transforms to the supplied Graphics object. MSDN should show you how, with a bit of playing: Graphics.RotateTransform[^] and Graphics.ScaleTransform[^]

If I remember correctly, you should find it is just a case of calling the simplest version of each, once in each Paint event. You may need to play with the order because the transforms are cumulative, IIRC
