geozl
Python bindings for geozl, geospatial codec extensions for OpenZL.
import numpy as np
import geozl
tile = np.fromfile("b04.raw", dtype=np.uint16).reshape(1024, 1024)
g = geozl.graph(tile, "planar>zigzag>transpose>entropy")
frame = geozl.compress(tile, graph=g)
back = geozl.decompress(frame).view(np.uint16).reshape(1024, 1024)
Pass a positive number as error for a fixed absolute bound, or a percentage
string for a relative bound. None and zero are lossless. Full LINEAR, LOG
and SQRT recipes remain available.
absolute = geozl.graph(tile, "planar>zigzag>entropy", error=2)
relative = geozl.graph(tile, "planar>zigzag>entropy", error="1%")
profile returns a list-like result. Print it to see the input geometry,
benchmark settings and ranked graphs together.
rows = geozl.profile(tile, prior=None)
print(rows)
best = rows[0]["graph"]
Twelve codecs, lossless and lossy, reachable two ways. geozl.graph takes a
recipe string and builds the graph for you, and geozl.compress runs one tile
through it. geozl.lossless and geozl.lossy hand you the individual nodes to
place in an OpenZL graph yourself, and geozl.register_decoders teaches a
DCtx to read what they wrote.
Wheels carry a prebuilt native library. A source install has to build it first, see the build instructions in the repository.
The full documentation, the codec catalogue and the wire format live in the repository.
