OpenSolaris 2009.06 - man page for fax2ps (opensolaris section 1)

fax2ps(1)				  User Commands 				fax2ps(1)

NAME
       fax2ps - convert a TIFF facsimile to compressed PostScript

SYNOPSIS
       fax2ps [options] [file]

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

OPTIONS
       The following options are supported:

       -H height       Use height as the height, in inches, of the output page. The default  page
		       height is 11 inches.

       -p number       Print  only  the  indicated  page.  To  print multiple pages, specify this
		       option as often as required.

       -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.  The  default  page
		       width is 8.5 inches.

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

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

OPERANDS
       The following operands are supported:

       file	       The  name  of  the TIFF facsimile image file to be converted to compressed
		       PostScript.

EXTENDED DESCRIPTION
       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, 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.  You	can  use  the  -p
       option to select one or more pages from a multipage 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  descrip-
       tion,  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 efficient to send the raster bitmap image
       directly, see tiff2ps(1).  If the destination printer supports PostScript Level II, it  is
       always faster to just send the encoded bitmap generated by the tiff2ps(1) command.

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

       Various	messages about badly formatted facsimile images may be generated due to transmis-
       sion 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 hori-
       zontal black lines in the resultant PostScript image.
