<DD>Encode the uncompressed source image associated with this compressor

instance into a YUV planar image and return a <code>YUVImage</code>

instance containing the encoded image. This method uses the accelerated

color conversion routines in TurboJPEG's underlying codec but does not

execute any of the other steps in the JPEG compression process. Encoding

CMYK source images to YUV is not supported.
