You should not rotate anything in the
PictireBox
, to stay out of trouble. Of course, it's possible to achieve but makes no sense at all. This control is often abused; it is designed to do most simple things such as showing some static image. If you try to do anything interactive, dynamic or animated with it, you can make it working, but this control does not help you at all, it only presents an intermediate level doing nothing useful, only eating up some extra resources, compromising performance and taking extra development effort giving nothing in return.
Instead, you need something very different; the best would be the custom control where you render your graphics directly. I explain how to do it in my past answers:
How do I clear a panel from old drawing[

draw a rectangle in C#[

Append a picture within picturebox[
