Classes:

  • LinearQuantize –

    Lossy codec to reduce the precision of floating point data.

LinearQuantize 

LinearQuantize(bits, dtype, _version='0.1.0')

Lossy codec to reduce the precision of floating point data.

The data is quantized to unsigned integers of the best-fitting type. The range and shape of the input data is stored in-band.

Parameters:
  • bits (...) –

    Binary precision of the encoded data where \(bits = \log_{2}(bins)\)

  • dtype (...) –

    Dtype of the decoded data

  • _version (..., default: = "0.1.0" ) –

    The codec's encoding format version. Do not provide this parameter explicitly.

Methods:

  • decode –

    Decode the data in buf.

  • encode –

    Encode the data in buf.

  • from_config –

    Instantiate the codec from a configuration dict.

  • get_config –

    Returns the configuration of the codec.

decode 

decode(buf, out=None)

Decode the data in buf.

Parameters:
  • buf (Buffer) –

    Encoded data. May be any object supporting the new-style buffer protocol.

  • out (Buffer, default: None ) –

    Writeable buffer to store decoded data. N.B. if provided, this buffer must be exactly the right size to store the decoded data.
Returns:
  • dec( Buffer ) –

    Decoded data. May be any object supporting the new-style buffer protocol.

encode 

encode(buf)

Encode the data in buf.

Parameters:
  • buf (Buffer) –

    Data to be encoded. May be any object supporting the new-style buffer protocol.
Returns:
  • enc( Buffer ) –

    Encoded data. May be any object supporting the new-style buffer protocol.

from_config classmethod 

from_config(config)

Instantiate the codec from a configuration dict.

Parameters:
  • config (dict) –

    Configuration of the codec.
Returns:
  • codec( Self ) –

    Instantiated codec.

get_config 

get_config()

Returns the configuration of the codec.

numcodecs.registry.get_codec(config) can be used to reconstruct this codec from the returned config.

Returns:
  • config( dict ) –

    Configuration of the codec.
