		const osgDB::ReaderWriter::Options *	options,
		bool	flipOutputImage,
		EffectTextureType	textureType,
		bool	verbose,
		bool	generate_dds
	)

Encrypt a image from a file.

options = null means use default behavior (ex. for medftool)

		const std::string &	inputFilename,
		const std::string &	outputFile,
		bool	flipOutputImage,
		EffectTextureType	textureType,
		bool	generateMipMaps,
		int	qualityLevel,
		bool	verbose,
		bool	generate_dds
	)

Create a compressed image.
