About

JPEG-2000 encoded and decoder for of Zarr chunks using imagecodecs. Works with 2D and interleaved RGB data.

Usage

from zarr_jpeg2k import jpeg2k
import numpy as np
import zarr
codec = jpeg2k(level=50)
data = np.arange(100000000, dtype='uint8').reshape(10000, 10000)
# without zarr
encoded = codec.encode(data)
decoded = codec.decode(encoded)
# with zarr
z = zarr.array(data, chunks=(1000, 1000), compressor=codec)
