Need I prepend any header information to the buffer before creating
the Image object?
Well, does it work if you save your data to a file, then create Image
object giving it the file name? If that fails, the problem is with your
data.
The MS documentation does not disclose much about
the requirements of the IStream object.
It should be image data in one of the formats GDI+ understands, e.g.
BMP, GIF or JPG.
You mentioned "raw pixel data", whatever that means. Perhaps if you can
massage it into one of the formats compatible with Windows bitmaps, you
could use Bitmap(BITMAPINFO*, void*) or Bitmap(int, int, int,
PixelFormat, BYTE*) constructors. See documentation on BITMAPINFO and
BITMAPINFOHEADER for a description of supported formats.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
