NoCompress#

class astropy.io.fits.hdu.compressed._codecs.NoCompress[source]#

Bases: Codec

A dummy compression/decompression algorithm that stores the data as-is.

While the data is not compressed/decompressed, it is converted to big endian during encoding as this is what is expected in FITS files.

Attributes Summary

Methods Summary

decode(buf)

encode(buf)

Compress the data in the buffer using the NOCOMPRESS algorithm.
