Decode and validate ZEN pixel-stream payloads.

Functions:

decode_frame –

Decode a row-major grayscale payload with a caller-supplied dtype.
decode_pixel_payload –

Decode a ZEN payload using its protocol pixel type metadata.
runtime_grayscale_dtype –

Return and validate the dtype reported by a streamed grayscale frame.

decode_frame(raw_data: bytes, dtype: dtype, width: int, height: int) -> np.ndarray

Decode a row-major grayscale payload with a caller-supplied dtype.

decode_pixel_payload(raw_data: bytes, width: int, height: int, pixel_type: PixelType) -> np.ndarray

Decode a ZEN payload using its protocol pixel type metadata.

runtime_grayscale_dtype(pixel_type: PixelType, payload_size: int, width: int, height: int) -> np.dtype

Return and validate the dtype reported by a streamed grayscale frame.
