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.
- -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 automatically 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.
There are styles called R, I, B, and BI mounted at
font positions 1 to 4.
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.
Grohtml has been completely redesigned and rewritten. It is still beta
code.
