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  auto-
	      matically 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.
