tf.image.rot90

Rotate image(s) counter-clockwise by 90 degrees.

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 4-D Tensor of shape [batch, height, width, channels] or 3-D Tensor of shape [height, width, channels].
k A scalar integer. The number of times the image is rotated by 90 degrees.
name A name for this operation (optional).
Returns
A rotated tensor of the same type and shape as image.
Raises
ValueError if the shape of image not supported.
