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.
