I believe the following scheme may work (untested):

...[assume handle is, in fact, a handle to a PICT and you have set up
rect.]
   (let* ((size (#_GetHandleSize handle))
          (workspace (#_NewHandle (* size 2)))) ;may need to add a little
extra!
      (if (handlep workspace)
        (progn
          (#_DisposeHandle workspace)
          (#_DrawPicture handle rect))
        [suitable error message or action]
        ))
