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

| ## Args ||
|---|---|
| `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). |

<br />

<br />

<br />

<br />

| ## Returns ||
|---|---|
| A rotated tensor of the same type and shape as `image`. ||

<br />

<br />

<br />

<br />

| ## Raises ||
|---|---|
| `ValueError` | if the shape of `image` not supported. |
