   -- once you have a handle you can do this :

   atom bm, width, height

   -- allocate structure memory for bitmap information.
   bm = w32acquire_mem( mset, SIZEOF_BITMAP )
   -- fill the structure with the bitmap information.
   ok = xGetObject( handle_of_bitmap, SIZEOF_BITMAP, bm )
   -- fetch the info that you want
   width  = fetch( bm, bmWidth )
   height = fetch( bm, bmHeight )
