tf.image.rot90

Rotate image(s) by 90 degrees.

tf.image.rot90( image, k=1, name=None )

Used in the notebooks

Used in the tutorials

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]] # rotating `a` clockwise by 180 degrees a_rot=tf.image.rot90(a, k=-2) print(a_rot[...,0].numpy()) [[4 3]  [2 1]]

image 4-D Tensor of shape [batch, height, width, channels] or 3-D Tensor of shape [height, width, channels].
k A scalar integer tensor. The number of times the image(s) are rotated by 90 degrees.
name A name for this operation (optional).

A rotated tensor of the same type and shape as image.

ValueError if the shape of image not supported.
