NAME
grohtml - html driver for groff
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, usu- ally html. -gaa-graphic-bits Number of bits of antialiasing information to be used by graph- ics when generating png images. The default is 4 but valid 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. -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 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 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 dis- plays 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.
