Jpeg Compression/Decompression with GPU?

Is it possible to increase the speed of the .NET jpeg encoder/decoder with Cudafy?
As GPU should be extremely fast with this stuff i think, and i would really like to improve the speed of it.

I would like to increase the speed of this:
           Bitmap bmp = new Bitmap(rc.Width, rc.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb;
            bmp.Save(ms, GetEncoderInfo(ImageFormat.Jpeg), JpegParam);
That conversion takes alot of time, it´s more than that, but just saving to a memorystream (even bmp) takes alot of time, so i would like to speed it up somehow, and i thought of GPGPU which hopefully can speed it up.

You will need to implement the Bitmap class in CUDAfy device code, so expect to do a lot of low-level programming.

NVIDIA's NPP has methods to handle it on the gpu, but it's fiendishly complex and NPP isn't currently supported by CUDAfy.
