epaper2in9b.py set_rotate fails with epdif undefined

[AndyThirtover]

As it says in the title, epdif is undefined. I tried this:

def set_rotate(self, rotate): if (rotate == ROTATE_0): self.rotate = ROTATE_0 self.width = EPD_WIDTH self.height = EPD_HEIGHT elif (rotate == ROTATE_90): self.rotate = ROTATE_90 self.width = EPD_HEIGHT self.height = EPD_WIDTH elif (rotate == ROTATE_180): self.rotate = ROTATE_180 self.width = EPD_WIDTH self.height = EPD_HEIGHT elif (rotate == ROTATE_270): self.rotate = ROTATE_270 self.width = EPD_HEIGHT self.height = EPD_WIDTH

But rotation didn't happen :(.

Regards
