FAX2PS(1)		    General Commands Manual		     FAX2PS(1)

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 com-
       pressed 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), re-
       spectively.  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.	Alter-
       nate page dimensions can	be specified in	inches with the	-W and -H  op-
       tions.

       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	 Post-
       Script  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	opera-
       tor.  This algorithm can, however, be ineffective  for  continuous-tone
       and  white-on-black images.  For	these images, it sometimes is more ef-
       ficient 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	dimen-
		 sions.	 By default images are presented according to the  di-
		 mension 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	gener-
       ated 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 al-
       ways 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 com-
       pressing	the output and just generate PostScript	to  image  the	bitmap
       raster instead.
