package lzw Import Path compress/lzw (on golang.org and go.dev) Dependency Relation imports 4 packages, and imported by one packageInvolved Source Files Package lzw implements the Lempel-Ziv-Welch compressed data format, described in T. A. Welch, ``A Technique for High-Performance Data Compression'', Computer, 17(6) (June 1984), pp 8-19. In particular, it implements LZW as used by the GIF and PDF file formats, which means variable-width codes up to 12 bits and the first two non-literal codes are a clear code and an EOF code. The TIFF file format uses a similar but incompatible version of the LZW algorithm. See the golang.org/x/image/tiff/lzw package for an implementation. writer.goPackage-Level Type Names (only one)Package-Level Functions (total 2)NewReader creates a new io.ReadCloser. Reads from the returned io.ReadCloser read and decompress data from r. If r does not also implement io.ByteReader, the decompressor may read more data than necessary from r. It is the caller's responsibility to call Close on the ReadCloser when finished reading. The number of bits to use for literal codes, litWidth, must be in the range [2,8] and is typically 8. It must equal the litWidth used during compression.NewWriter creates a new io.WriteCloser. Writes to the returned io.WriteCloser are compressed and written to w. It is the caller's responsibility to call Close on the WriteCloser when finished writing. The number of bits to use for literal codes, litWidth, must be in the range [2,8] and is typically 8. Input bytes must be less than 1<<litWidth.Package-Level Constants (total 2)LSB means Least Significant Bits first, as used in the GIF file format.MSB means Most Significant Bits first, as used in the TIFF and PDF file formats.
