NAME

       compression_overview - File compression Coin can support reading and writing Inventor and
       VRML files compressed with either gzip or bzip2 (as of yet - more formats may come in the
       future). This functionality is of course only enabled when Coin can link with the
       corresponding compression libraries.

       Reading of compressed files happens in a transparent manner - there is nothing the
       developer has to do to support this.

       Writing of compressed files is controlled through the SoOutput::setCompression method.

       The list of available compression methods can be fetched with the
       SoOutput::getAvailableCompressionMethods method.

       You can not use file compression together with I/O to memory buffers, except for reading
       from memory buffers containing gzip-compressed files.

       For backwards compatibility with Coin 2.0 and Coin 1.0, compressed files must not be used.
       Compressed files works only from Coin 2.1 and upwards.

       Since:
           Coin 2.1
