NAME

6       compression_overview - File compression Coin can support reading and
7       writing Inventor and VRML files compressed with either gzip or bzip2
8       (as of yet - more formats may come in the future). This functionality
9       is of course only enabled when Coin can link with the corresponding
10       compression libraries.
11
12       Reading of compressed files happens in a transparent manner - there is
13       nothing the developer has to do to support this.
14
15       Writing of compressed files is controlled through the
16       SoOutput::setCompression method.
17
18       The list of available compression methods can be fetched with the
19       SoOutput::getAvailableCompressionMethods method.
20
21       You can not use file compression together with I/O to memory buffers,
22       except for reading from memory buffers containing gzip-compressed
23       files.
24
25       For backwards compatibility with Coin 2.0 and Coin 1.0, compressed
26       files must not be used. Compressed files works only from Coin 2.1 and
27       upwards.
