You can use the DuplicateHandle Win32 API function
to create a handle to a graphical object in a
different process. There are access restrictions
and all that to worry about naturally.
But if performance is an issue i'd expect that to
be much faster than sharing a memorymapped
metafile or allocating the memory yourself
and writing DIB data to it.

Since you
