Answer 1

I use use a MemoryStream:

var source = RasterImageConverter.ConvertToSource(ScanImage, ConvertToSourceOptions.None) as BitmapSource;
byte[] data;
JpegBitmapEncoder encoder = new JpegBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(source));
using (MemoryStream ms = new MemoryStream())
{
   encoder.Save(ms);
   data = ms.ToArray();
}
