Obtains the shape of the encoded image.

Supported backends

  • ‘cpu’

Parameters:

__input (TensorList) – Input to the operator.

Keyword Arguments:

  • adjust_orientation (bool, optional, default = True) – Use the EXIF orientation metadata when calculating the shape.

  • bytes_per_sample_hint (int or list of int, optional, default = [0]) –

    Output size hint, in bytes per sample.

    If specified, the operator’s outputs residing in GPU or page-locked host memory will be preallocated to accommodate a batch of samples of this size.

  • dtype (nvidia.dali.types.DALIDataType, optional, default = DALIDataType.INT64) – Data type, to which the sizes are converted.

  • image_type (nvidia.dali.types.DALIImageType, optional, default = DALIImageType.RGB) – Color format of the image.

  • preserve (bool, optional, default = False) – Prevents the operator from being removed from the graph even if its outputs are not used.

  • seed (int, optional, default = -1) –

    Random seed.

    If not provided, it will be populated based on the global seed of the pipeline.
