public class SoJpegDataCompressor
extends SoDataCompressor

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

The setCompressionLevel method (SoDataCompressor or 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.

Limitations:

• JPEG compression can only be used on 8-bit data sets.
