I find following functions:

CompressDXT.h(45):void compressDXT3(const nvtt::OutputOptions::Private & outputOptions); CompressDXT.h(64):void compressDXT3(const nvtt::CompressionOptions::Private & compressionOptions, const nvtt::OutputOptions::Private & outputOptions); OptimalCompressDXT.h(44): void compressDXT3A(const ColorBlock & rgba, AlphaBlockDXT3 * dxtBlock); QuickCompressDXT.h(43):void compressDXT3(const ColorBlock & rgba, BlockDXT3 * dxtBlock); CompressDXT.h(45):void compressDXT3(const nvtt::OutputOptions::Private & outputOptions); CompressDXT.h(64):void compressDXT3(const nvtt::CompressionOptions::Private & compressionOptions, const nvtt::OutputOptions::Private & outputOptions); OptimalCompressDXT.h(44): void compressDXT3A(const ColorBlock & rgba, AlphaBlockDXT3 * dxtBlock); QuickCompressDXT.h(43):void compressDXT3(const ColorBlock & rgba, BlockDXT3 * dxtBlock);

how to use those functions？ how to compress or decompress image texture using OpenScenGraph ?and how to make jpg texture image maintain jpg format,then make ive or osgb file smaller?
