I. I don’t understand how to specify image’s orientation.

• Step 1: I specify the image’s orientation using

  magick 0.jpg -orient top-left 1.jpg
  

• Step 2: I rotate the image using

  magick 1.jpg -rotate 90 2.jpg
  

• Step 3: I try to restore the orientation I have specified earlier using

  magick 2.jpg -auto-orient 3.jpg
  

I expected that 3.jpg will be rotated -90 degrees, and so it will appear as 0.jpg and 1.jpg, but this doesn’t happen, and it still appear as 2.jpg.

Am I doing something wrong?

II. Also, I don’t understand how to find out the specified orientation. I tried

magick identify -format "%[orientation]" 3.jpg

but this returns Undefined.
