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
	      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 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	 gro-
	      html-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.
