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
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.
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.
