NAME

       fax2ps - convert a TIFF facsimile to compressed PostScripttm

SYNOPSIS

       fax2ps [ options ] [ file ... ]

DESCRIPTION

       fax2ps  reads  one  or  more  TIFF  facsimile  image files and prints a
       compressed form of PostScript on the standard output that  is  suitable
       for printing.

       By  default,  each  page  is scaled to reflect the image dimensions and
       resolutions stored in the file.  The -x and -y options can be  used  to
       specify  the  horizontal  and  vertical image resolutions (lines/inch),
       respectively.  If the -S option is specified, each page  is  scaled  to
       fill  an  output  page.   The  default output page is 8.5 by 11 inches.
       Alternate page dimensions can be specified in inches with the -W and -H
       options.

       By  default fax2ps generates PostScript for all pages in the file.  The
       -p option can be used to select one or more  pages  from  a  multi-page
       document.

       fax2ps  generates a compressed form of PostScript that is optimized for
       sending pages of text to  a  PostScript  printer  attached  to  a  host
       through  a low-speed link (such as a serial line).  Each output page is
       filled with white and  then  only  the  black  areas  are  drawn.   The
       PostScript  specification  of the black drawing operations is optimized
       by using a special font that encodes the move-draw operations  required
       to  fill  the  black  regions  on  the  page.   This compression scheme
       typically results in a substantially  reduced  PostScript  description,
       relative  to  the straightforward imaging of the page with a PostScript
       image operator.   This  algorithm  can,  however,  be  ineffective  for
       continuous-tone  and  white-on-black  images.   For  these  images,  it
       sometimes is more efficient to send the raster bitmap  image  directly;
       see tiff2ps(1).

OPTIONS

       -p number Print only the indicated page.  Multiple pages may be printed
                 by specifying this option more than once.

       -x resolution
                 Use resolution as the horizontal resolution, in dots/inch, of
                 the  image  data.   By  default  this value is taken from the
                 file.

       -y resolution
                 Use resolution as the vertical resolution, in lines/inch,  of
                 the  image  data.   By  default  this value is taken from the
                 file.

       -S        Scale each page  of  image  data  to  fill  the  output  page
                 dimensions.  By default images are presented according to the
                 dimension information recorded in the TIFF file.

       -W width  Use width as the width, in inches, of the output page.

       -H height Use height as the height, in inches, of the output page.

DIAGNOSTICS

       Some messages about malformed TIFF images come from the TIFF library.

       Various  messages  about  badly  formatted  facsimile  images  may   be
       generated  due  to  transmission  errors in received facsimile.  fax2ps
       attempts to recover from such data errors by  resynchronizing  decoding
       at the end of the current scanline.  This can result in long horizontal
       black lines in the resultant PostScript image.

NOTES

       If the destination printer supports PostScript  Level  II  then  it  is
       always  faster  to  just  send  the  encoded  bitmap  generated  by the
       tiff2ps(1) program.

BUGS

       fax2ps should probably figure out when  it  is  doing  a  poor  job  of
       compressing the output and just generate PostScript to image the bitmap
       raster instead.
