anyone has alternative for Bitmap.FromStream in compact framework?

Hi,
I want to port this line of code to c# in compact framework:
Bitmap bmp = (Bitmap) Bitmap.FromStream(new MemoryStream(buffer, start, stop - start));

but Bitmap.FromStream does not exists....

Anyone has piece of code to work arround it?

thanks

i can do this:

MemoryStream mem = new MemoryStream(buffer, start, stop - start);
Bitmap bmp = new Bitmap(mem);

but this gives me an exception on the last sentence....
in c# in .net on desktop this works fine....

i'm trying to visualize a mjpeg stream from an ip-camera...
anyone did this before?
