NAME
       grohtml - html driver for groff

SYNOPSIS
grohtml [ -bhlnprv ] [ -aaa-text-bits ] [ -Ddir ] [ -Fdir ]
               [ -gaa-graphic-bits ] [ -iresolution ] [ -Iimage-stem ]
               [ -jfilename ] [ -oimage-vertical-offset ] [ -ssize ]
               [ -Slevel ] [ 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 valid 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.

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

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

       -gaa-graphic-bits
              Number of bits of antialiasing information to be used by
              graphics when generating png images.  The default is 4 but valid
              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.

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

       -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).

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

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

       -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 older versions of some browsers (Netscape).
              This flag is automatically turned on if a heading contains an
              image.

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

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

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

       -s size
              Set the base point size of the source file.  Thereafter when
              this point size is used in the source it will correspond to the
              html base size.  Every increase of two points in the source will
              yield a <big> tag, and conversely when a decrease of two points
              is seen a <small> tag is emitted.

       -Slevel
              When splitting html output, split at the heading level (or
              higher) defined by level.

       -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 beta
       code.
