Is there any way to rotate a PImage without having to draw it to the screen?

Basically what I am trying to do is load an external image, rotate it 90 degrees, then save it out.

But, I do not want to draw the image to the stage. So, how would one do that?

I guess I can write a custom script that would rearrange all the pixels in the image, but I was hoping there is some easier built-in way of accomplishing this?

Thanks!
