imagecodecs-lite 2019.4.20

Subset of image transformation, compression, and decompression codecs

Imagecodecs-lite is a Python library that provides block-oriented, in-memory buffer transformation, compression, and/or decompression functions for LZW, PackBits, Delta, XOR Delta, Packed Integers, Floating Point Predictor, and Bitorder reversal.

Imagecodecs-lite is a subset of the imagecodecs library, which provides additional codecs for Zlib DEFLATE, ZStandard, Blosc, LZMA, BZ2, LZ4, LZF, ZFP, PNG, WebP, JPEG 8-bit, JPEG 12-bit, JPEG SOF3, JPEG LS, JPEG 2000, and JPEG XR.

Unlike imagecodecs, imagecodecs-lite does not depend on external third-party C libraries and is therefore simple to build from source code.
