ZFPY#
- class numcodecs.zfpy.ZFPY(mode=4, tolerance=-1, rate=-1, precision=-1, compression_kwargs=None)[source]#
Codec providing compression using zfpy via the Python standard library.
- Parameters:
- modeinteger
One of the zfpy mode choice, e.g.,
zfpy.mode_fixed_accuracy.- tolerancedouble, optional
A double-precision number, specifying the compression accuracy needed.
- ratedouble, optional
A double-precision number, specifying the compression rate needed.
- precisionint, optional
A integer number, specifying the compression precision needed.
- codec_id: str | None = 'zfpy'#
Codec identifier.
- encode(buf)[source]#
Encode data in buf.
- Parameters:
- bufbuffer-like
Data to be encoded. May be any object supporting the new-style buffer protocol.
- Returns:
- encbuffer-like
Encoded data. May be any object supporting the new-style buffer protocol.
- decode(buf, out=None)[source]#
Decode data in buf.
- Parameters:
- bufbuffer-like
Encoded data. May be any object supporting the new-style buffer protocol.
- outbuffer-like, optional
Writeable buffer to store decoded data. N.B. if provided, this buffer must be exactly the right size to store the decoded data.
- Returns:
- decbuffer-like
Decoded data. May be any object supporting the new-style buffer protocol.
