NAME

       grohtml - html driver for groff


SYNOPSIS

       grohtml [ -vhlrn ] [ -Ddir ] [ -Fdir ] [ -iresolution ]
               [ -Iimage-stem ] [ -oimage-vertical-offset ] [ -aaa-text-bits ]
               [ -aaa-graphic-bits ] [ files... ]


DESCRIPTION

       The  grohtml  front end (which consists of a preprocessor, pre-grohtml,
       and a device driver, post-grohtml) translates the output of  GNU  troff
       to html.  Users should always invoke grohtml via the groff command with
       a -Thtml option.  If no files are given, grohtml will read the standard
       input.   A  filename  of - will also cause grohtml to read the standard
       input.  Html output is written to the standard output.  When grohtml is
       run  by groff options can be passed to grohtml using groff's -P option.


OPTIONS

       -aaa-text-bits
              Number of bits of antialiasing information to be  used  by  text
              when  generating  png images.  The default is 4 but legal values
              are 0, 1, 2, and 4.  Note your version of gs  needs  to  support
              the  -dTextAlphaBits  and -dGraphicAlphaBits options in order to
              exploit antialiasing.  A value of 0 stops grohtml  from  issuing
              antialiasing commands to gs.

       -gaa-graphic-bits
              Number  of bits of antialiasing information to be used by graph-
              ics when generating png images.  The default is 4 but legal val-
              ues  are  0, 1, 2, and 4.  Note your version of gs needs to sup-
              port the -dTextAlphaBits and -dGraphicAlphaBits options in order
              to  exploit antialiasing.  A value of 0 stops grohtml from issu-
              ing antialiasing commands to gs.

       -b     Initialize the background color to white.

       -h     Generates section and number headings by  using  <B>...</B>  and
              increasing  the  font  size,  rather than using the <Hn>...</Hn>
              tags.

       -l     Turns off the production of automatic section links at  the  top
              of the document.

       -r     Turns off the automatic header and footer line (html rule).

       -n     Generate  simple heading anchors whenever a section/number head-
              ing is found.  Without the option the anchor value is  the  tex-
              tual heading.  This can cause problems when a heading contains a
              `?' on some browsers (netscape).   This  flag  is  automatically
              turned on if a heading contains an image.

       -p     Display  page  rendering  progress to stderr.  grohtml only dis-
              plays a page number when an image is required.

       -Fdir  Prepend directory dir/devname to the search path  for  font  and
              device  description  files; name is the name of the device, usu-
              ally html.

       -iresolution
              Select the resolution for all images.  By default  this  is  100
              pixels  per inch.  Example: -i200 indicates 200 pixels per inch.

       -Istem Determine the image stem name.  If omitted grohtml uses grohtml-
              XXX (XXX is the process ID).

       -overtical-offset
              Specify the vertical offset of images in points.

       -Ddir  Inform grohtml to place all image files into directory dir.

       -jfilename
              Inform  grohtml  to  split  the html output into multiple files.
              The filename is the stem and  all  level  one  section  headings
              start a new file, named filename-n.html.

       -v     Print the version number.


USAGE

       There  are styles called R, I, B, and BI mounted at font positions 1 to
       4.


DEPENDENCIES

       grohtml is dependent upon the png utilities (pnmcut, pnmcrop, pnmtopng)
       and  GhostScript (gs).  pnmtopng (version 2.37.6 or greater) and pnmcut
       from the netpbm package (version 9.16 or greater) will work  also.   It
       is  also  dependent upon psselect from the PSUtils package.  Images are
       generated whenever a table, picture, equation or line is encountered.


BUGS

       Grohtml has been completely redesigned  and  rewritten.   It  is  still
       alpha code.
