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 PostScript that is suitable for printing on the stan-
       dard 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  dimen-
		       sion 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 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 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).
       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 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.
