    tf.io.extract_jpeg_shape(
        contents: _atypes.TensorFuzzingAnnotation[_atypes.String],
        output_type: TV_ExtractJpegShape_output_type = https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/dtypes#int32,
        name=None
    ) -> _atypes.TensorFuzzingAnnotation[TV_ExtractJpegShape_output_type]

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`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/dtypes/DType) from: `tf.int32, tf.int64`. Defaults to [`tf.int32`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf#int32). (Optional) The output type of the operation (int32 or int64). Defaults to int32. |
| `name` | A name for the operation (optional). |
