<DD>Encode the uncompressed source image associated with this compressor
instance and output a YUV planar image to the given destination buffer.
- This method uses the accelerated color conversion routines in

- suitable for direct video display. Specifically, if the chrominance
- components are subsampled along the horizontal dimension, then the width
- of the luminance plane is padded to the nearest multiple of 2 in the
- output image (same goes for the height of the luminance plane, if the
- chrominance components are subsampled along the vertical dimension.)
- Also, each line of each plane in the output image is padded to 4 bytes.
- Although this will work with any subsampling option, it is really only
- useful in combination with <A HREF="../../../org/libjpegturbo/turbojpeg/TJ.html#SAMP_420"><CODE>TJ.SAMP_420</CODE></A>, which produces an image
- compatible with the I420 (AKA "YUV420P") format.
+ 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. The Y, U, and V image planes are stored sequentially
+ into the destination buffer, and the size of each plane is determined by
+ the width and height of the source image, as well as the specified padding
+ and level of chrominance subsampling. If the chrominance components are
+ subsampled along the horizontal dimension, then the width of the luminance
+ plane is padded to the nearest multiple of 2 in the output image (same
+ goes for the height of the luminance plane, if the chrominance components
+ are subsampled along the vertical dimension.)
