tf.image.rot90
  
  Rotate image(s) counter-clockwise by 90 degrees.
  
  tf.image.rot90(
    image, k=1, name=None
)
  For example:
  a=tf.constant([[[1],[2]],
               [[3],[4]]])
# rotating `a` counter clockwise by 90 degrees
a_rot=tf.image.rot90(a)
print(a_rot[...,0].numpy())
[[2 4]
 [1 3]]
# rotating `a` counter clockwise by 270 degrees
a_rot=tf.image.rot90(a, k=3)
print(a_rot[...,0].numpy())
[[3 1]
 [4 2]]
  
   
    
     
     
    
    
     
      | Args | 
     
     
      image |
