WebMay 29, 2024 · You know the LZW stream can be encoded at any bitlength (not just 8/16/32/64 bits) which can greatly affect compression ratios (in respect to used data properties). So I would try to do univeral access to data at variable (or predefined bitlength). Was a bit curious so I encoded a simple C++/VCL example for the compression: WebAug 11, 2024 · * *****/ /** * The {@code LZW} class provides static methods for compressing * and expanding a binary input using LZW compression over the 8-bit extended * ASCII alphabet with 12-bit codewords. *
