15 The grohtml front end (which consists of a preprocessor, pre-grohtml,
16 and a device driver, post-grohtml) translates the output of GNU troff
17 to html. Users should always invoke grohtml via the groff command with
18 a -Thtml option. If no files are given, grohtml will read the standard
19 input. A filename of - will also cause grohtml to read the standard
20 input. Html output is written to the standard output. When grohtml is
21 run by groff options can be passed to grohtml using groff's -P option.
22
24 -aaa-text-bits
25 Number of bits of antialiasing information to be used by text
26 when generating png images. The default is 4 but valid values
27 are 0, 1, 2, and 4. Note your version of gs needs to support
28 the -dTextAlphaBits and -dGraphicAlphaBits options in order to
29 exploit antialiasing. A value of 0 stops grohtml from issuing
30 antialiasing commands to gs.
31 -b Initialize the background color to white.
33 -Ddir Inform grohtml to place all image files into directory dir.
35 -e This option should not be directly invoked by the user as it is
37 an internal option utilized by groff when -Thtml or -Txhtml is
38 specified. It is used by the grohtml preprocessor to determine
39 whether eqn should attempt to produce MathML (if -Txhtml is
40 specified).
41 -Fdir Prepend directory dir/devname to the search path for font and
43 device description files; name is the name of the device, usu‐
44 ally html.
45 -gaa-graphic-bits
47 Number of bits of antialiasing information to be used by graph‐
48 ics when generating png images. The default is 4 but valid val‐
49 ues are 0, 1, 2, and 4. Note your version of gs needs to sup‐
50 port the -dTextAlphaBits and -dGraphicAlphaBits options in order
51 to exploit antialiasing. A value of 0 stops grohtml from issu‐
52 ing antialiasing commands to gs.
53 -h Generate section and number headings by using <B>...</B> and
55 increasing the font size, rather than using the <Hn>...</Hn>
56 tags.
57 -iresolution
59 Select the resolution for all images. By default this is 100
60 pixels per inch. Example: -i200 indicates 200 pixels per inch.
61 -Istem Determine the image stem name. If omitted grohtml uses
63 grohtml-XXX (XXX is the process ID).
64 -jfilename
66 Inform grohtml to split the html output into multiple files.
67 The filename is the stem and specified section headings (default
68 is level one) start a new file, named filename-n.html.
69 -l Turn off the production of automatic section links at the top of
71 the document.
72 -n Generate simple heading anchors whenever a section/number head‐
74 ing is found. Without the option the anchor value is the tex‐
75 tual heading. This can cause problems when a heading contains a
76 `?' on older versions of some browsers (Netscape). This flag is
77 automatically turned on if a heading contains an image.
78 -overtical-offset
80 Specify the vertical offset of images in points.
81 -p Display page rendering progress to stderr. grohtml only dis‐
83 plays a page number when an image is required.
84 -r Turn off the automatic header and footer line (html rule).
86 -s size
88 Set the base point size of the source file. Thereafter when
89 this point size is used in the source it will correspond to the
90 html base size. Every increase of two points in the source will
91 yield a <big> tag, and conversely when a decrease of two points
92 is seen a <small> tag is emitted.
93 -Slevel
95 When splitting html output, split at the heading level (or
96 higher) defined by level.
97 -v Print the version number.
99 -V Create an XHTML or HTML validator button at the bottom of each
101 page of the document.
102 -xdialect
104 Select HTML dialect. Currently, dialect should be either the
105 digit 4 or the letter x which indicates whether grohtml should
106 generate HTML 4 or XHTML, respectively. This option should not
107 be directly invoked by the user as it is an internal option uti‐
108 lized by groff when -Thtml or -Txhtml is specified.
109 -y Produce a right-justified groff signature at the end of the doc‐
111 ument. This is only generated if the -V flag is also specified.
112
114 There are styles called R, I, B, and BI mounted at font positions 1
115 to 4.
116
118 grohtml is dependent upon the png utilities (pnmcut, pnmcrop, pnmtopng)
119 and GhostScript (gs). pnmtopng (version 2.37.6 or greater) and pnmcut
120 from the netpbm package (version 9.16 or greater) will work also. It
121 is also dependent upon psselect from the PSUtils package. Images are
122 generated whenever a table, picture, equation or line is encountered.
123
125 GROFF_FONT_PATH
126 A list of directories in which to search for the devname direc‐
127 tory in addition to the default ones. See troff(1) and
128 groff_font(5) for more details.
129
131 Grohtml has been completely redesigned and rewritten. It is still beta
132 code.
