<hr><a name="_details"></a><h2>Detailed Description</h2>
This class will compress or decompress a YUV panel using the DCT.
<p>
<p>
This class does both forward and inverse DCT conversion of a YUV panel; the direction is specified at creation time in the constructor. In theory InverseDCT(ForwardDCT(yuv)) = yuv, that is, an image can be converted to DCT and back to its original.
