NAMEΒΆ
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
