zlib: elj compression interface


This is the elj interface to the zlib (version: ?).

zlib is designed to be a free, general-purpose, legally unencumbered -- that is, not covered by any patents -- lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1) and in the GIF image format, the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.


Documentation for the moment is limited to the source code:

and an example:

Note: For win32/lcc-win32 users we provide the appropriate lib (zlib_lcc.lib) file to work with the zlib interface:

For Linux users (for the moment), you will need to download zlib and compile for your system (alternatively it may already be configured to your system).
