DESCRIPTION

       The  tcl::transform::zlib  package  provides  a  command  creating  a  channel  transformation which zlib
       compresses the written data, and decompresses on reading.

       The internal TclOO class implementing the transform handler is a sub-class  of  the  tcl::transform::core
       framework.

API

       ::tcl::transform::zlib chan ?level?
              This  command  creates a zlib compressor transformation on top of the channel chan and returns its
              handle.

              The level specifies how much effort is put into the compression, from 0 to 9, and defaults to 4.
