What's Changed

Restore behaviour of accepting numpy integers as arguments to read functions by @da-wad in https://github.com/equinor/seismic-zfp/pull/100

Overview

This is a minor release rather than a patch release to signify that numpy 2 compatibility can be expected, provided that zfpy>=1.0.1 is installed. Functions deprecated in numpy 2 have been removed, but since this is a pure-Python module some environments using numpy<2.0 and zfpy<1.0.1 can also be expected to work.

What's Changed

Remove numpy-1.x dependency restriction as zfpy and pyzgy are np-2.x compatible by @da-wad in https://github.com/equinor/seismic-zfp/pull/96

seismic-zfp - v0.3.6

adds usehighersamples_precision option to StreamConverter
- Specifies whether to use higher precision for the sample interval and sample time. Default is False. When set to True, stores sample interval and sample time as 64-bit floating-point numbers for increased precision. If False, they are stored as 32-bit integers.

Published by ThomasRyschawyEquinor over 1 year ago

seismic-zfp - v0.3.5

Added new StreamConverter
- similar to NumpyConverter
- compresses a 3D numpy array to an SGZ file as a stream of chunks
- enables sequential compression without loading the entire array into memory
Updated Numpy requirements to <2.0.0
