How can I get untransformed image?

This issue is related to rotation.
On the screenshot, there is a group that has one rectangle and one image.
And its rotation is 45deg. So its children(rectangle and image) are rotated.
In this case, if I export the image as renditions, the exported image is like the above one.

But I want to get the original image that hasn’t been rotated by its parent or by itself.

I am not sure how I can resolve this issue.
Looking forward to the perfect answer.
