Proportional and exotic fonts are not required. Randy, your best bet is to let ghostscript (http://www.cs.wisc.edu/~ghost) do the job in terms of rendering the text and createing a TIFF G4 file. Assuming you can have the textual information in a snipped to postscript code, you can then let ghostscript encapsulate it and then output a tiff file including only what's in the postscript bounding box. You could even take this a step further, by converting the original image (the one to be annotated) to postscript (as a bitmap), let ghostscript rasterize it, overlay the annotation on it, and then write it out as a TIFF G4 file. May be a bit obstruse, but it should work. -- Alberto **************************************************************************** Alberto Accomazzi NASA Astrophysics Data System / SIMBAD USA aaccomazzi@cfa.harvard.edu Smithsonian Astrophysical Observatory v/f: 617-495-7076/617-496-7577 60 Garden Street, Mail Stop 83 http://cfa-www.harvard.edu/~alberto Cambridge, MA 02138 USA ****************************************************************************
