I am trying to export scetches from DraftSight into a JPEG format.  Not a drawing, just a sketch in modelspace.  I have a white backgroung and black model lines. All other layers are turned off or irrelevant.  The JPEG image has a black background and grey model lines.  This is not what i want.  If I make the background black and models green (or some other color) then it comes in right.  Any advice on this problem?
