  summary: Image transformation, compression, and decompression codecs
  description: |
    The imagecodecs package provides various block-oriented, in-memory buffer
    transformation, compression, and decompression functions for use in the
    tifffile, czifile, and other Python imaging modules.

    Decode and/or encode functions are currently implemented for Zlib DEFLATE,
    ZStandard, Blosc, LZMA, BZ2, LZ4, LZW, LZF, PNG, WebP, JPEG 8-bit,
    JPEG 12-bit, JPEG SOF=0xC3, JPEG 2000, JPEG XR, PackBits, Packed Integers,
    Delta, XOR Delta, Floating Point Predictor, and Bitorder reversal.
