%description
Imagecodecs is a Python library that provides block-oriented, in-memory buffer
transformation, compression, and decompression functions for use in the
tifffile, czifile, and other scientific imaging modules.

Decode and/or encode functions are implemented for Zlib (DEFLATE), GZIP,
ZStandard (ZSTD), Blosc, Brotli, Snappy, LZMA, BZ2, LZ4, LZ4F, LZ4HC, LZW, LZF,
ZFP, AEC, LERC, NPY, PNG, GIF, TIFF, WebP, JPEG 8-bit, JPEG 12-bit, Lossless
JPEG (LJPEG, SOF3), JPEG 2000, JPEG LS, JPEG XR, JPEG XL, AVIF, PackBits, Packed
Integers, Delta, XOR Delta, Floating Point Predictor, Bitorder reversal,
Bitshuffle, and Float24 (24-bit floating point).
