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
graphics 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
heading is found. Without the option the anchor value is the
textual 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
displays 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, usually 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.
