Methods

	Name	Description
	AllocateCompressedBuffer	Allocates the internal buffer to hold the compressed data. (Inherited from SoDataCompressor.)
	Compress	Compresses the given buffer into the internal buffer. (Inherited from SoDataCompressor.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	GetCompressedBuffer	Returns the compressed data. (Inherited from SoDataCompressor.)
	GetCompressionFormatName	Returns the name of the compression algorithm used by this class. (Inherited from SoDataCompressor.)
	GetCompressionLevel	Returns the compression level. (Inherited from SoDataCompressor.)
	GetHashCode	Overrides GetHashCode(). (Inherited from SoNetBase.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsLossless	Returns true if the compression algorithm is lossless. (Inherited from SoDataCompressor.)
	SetCompressionLevel	Sets the compression level. (Inherited from SoDataCompressor.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Uncompress	Uncompresses data from the internal buffer to the given buffer. (Inherited from SoDataCompressor.)

Remarks

This class implements a compression scheme based on libjpeg. It is a lossy compression.

The setCompressionLevel method (OIV.LDM.Compressors.SoDataCompressor or OIV.LDM.Converters.SoConverterParameters) accepts values between 0 and 100. 0 gives best compression but most loss of data. 100 gives minimum compression and minimum data alteration. Default is 85.
