Adjust jpeg encoding quality of an image.

This is a convenience method that converts an image to uint8 representation, encodes it to jpeg with jpeg_quality, decodes it, and then converts back to the original data type.

jpeg_quality must be in the interval [0, 100].

image 3D image. Size of the last dimension must be None, 1 or 3.
jpeg_quality Python int or Tensor of type int32. jpeg encoding quality.
name A name for this operation (optional).

>> import tensorflow as tf
>> x = tf.random.normal(shape=(256, 256, 3))
>> tf.image.adjust_jpeg_quality(x, 75)

InvalidArgumentError quality must be in [0,100]
