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) trans-
       lates  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  issu-
              ing antialiasing commands to gs.

       -gaa-graphic-bits
              Number  of  bits  of  antialiasing  information  to be used by graphics 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.

       -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 heading is found.  Without the option the
              anchor value is the textual 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  displays 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, usually 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.

       -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  (ver-
       sion  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,  equa-
       tion or line is encountered.

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