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.
