tf.io.extract_jpeg_shape

Extract the shape information of a JPEG-encoded image.

Main aliases

tf.image.extract_jpeg_shape

Compat aliases for migration

tf.compat.v1.image.extract_jpeg_shape, tf.compat.v1.io.extract_jpeg_shape, `tf.compat.v2.image.extract_jpeg_shape`, `tf.compat.v2.io.extract_jpeg_shape`

tf.io.extract_jpeg_shape(
    contents, output_type=tf.dtypes.int32, name=None
)

This op only parses the image header, so it is much faster than DecodeJpeg.

Args
`contents`	A `Tensor` of type `string`. 0-D. The JPEG-encoded image.
`output_type`	An optional `tf.DType` from: `tf.int32, tf.int64`. Defaults to `tf.int32`. (Optional) The output type of the operation (int32 or int64). Defaults to int32.
`name`	A name for the operation (optional).

Returns
A `Tensor` of type `output_type`.
