Tiny utility package which has only one job: Provide a Python function which uses Schlumberger's ZGY library and LLNL's ZFP library to read ZGY files and write seismic-zfp (.SGZ) format files.

zgy2sgz is intended exclusively for use by the seismic-zfp package

from zgy2sgz import convertFile
# Yes, the first two arguments are bytes rather than strings
# The 3rd argument is bits_per_voxel {16, 8, 4, 2, 1}
convertFile(b'seismic_file.zgy', b'seismic_file.sgz', 4)

2023-10-20: Repository archived in Github cleanup as this package is no longer maintained, since pyzgy now provides the required functionality to semsic-zfp in a more maintainable way.
