Top left hand coordinate of the same viewport you wmfout from, inserted at a 2:1 scale. You mustn't change the zoom factor or view center between the wmfout and wmfin activities or else the result will be wack. You can be more precise by examining the viewport coordinates and comparing them to the wmfin block bounding box, but you will find the ration is pretty close to 2:1. Finally, set all your display vars to the maximum before the wmfout -- the quality of the export / import is directly related. Search this website for a proggy called hires, it will do most of the latter for you. Having said all this, wmfout / in usually produces a mess.
