    Hi,

    I just did some tests:
    scanning an image as lineart and saving it as pbm and as postscript via xsane fax option.
    Afterwards I convertedt the postscript file with the following command to a pbm file:
    gs -sDEVICE=pbmraw -r98 -q -dSAFER -dNOPAUSE -sOutputFile=xxx.pbm testfa
    x/page-001.ps

    There has been no visible difference between both outputs.

    Gs-Version:
    gs -v
    GNU Ghostscript 5.10 (1998-12-17)
    Copyright (C) 1997 Aladdin Enterprises, Menlo Park, CA. All rights reserved.

    So it look like ghostscript does not make any problems converting the created postscript files.
    May be the fax programs have problems setting the correct options for ghostscript - if they use
    ghostscript.

    So I see no reason to change anything in xsane.

    Any comments?

    Bye
    Oliver
