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.

    -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.
