Write

Writing SEGY files mirrors the reading workflow.

import numpy as np
import pysegy as seg

fh = seg.FileHeader()
fh.bfh.ns = 2
fh.bfh.DataSampleFormat = 5

# two traces with minimal headers
hdr = seg.BinaryTraceHeader()
hdr.ns = 2

data = np.array([[1.0], [2.0]], dtype=np.float32)
block = seg.SeisBlock(fh, [hdr], data)

seg.segy_write("out.segy", block)

The pysegy.segy_write helper takes a pysegy.SeisBlock and writes a complete SEGY file to disk.
