20 gxditview interprets and displays the intermediate output format of
21 groff(1) on an X11 display. It uses the standard X11 fonts, so it does
22 not require access to the server machine for font loading. There are
23 several ways to use gxditview.
24 The intermediate output format of groff, documented in groff_out(5), is
26 produced by troff or the -Z option to groff. It can be viewed by ex‐
27 plicitly calling “gxditview file”. If the file operand is “-”,
28 gxditview will read the standard input stream; file cannot be omitted.
29 The intermediate output format of groff is device-independent but not
30 device-agnostic. gxditview can view it for all typesetter devices, but
31 the quality is device-dependent. gxditview will not display output for
32 terminal (nroff) devices.
33 The best results are achieved with the X* devices for groff's -T op‐
35 tion, of which there are four: -TX75, -TX75-12, -TX100, and -TX100-12.
36 They differ by the X resolution (75 or 100 dots per inch) and the base
37 point size (10 or 12 points). They are especially built for gxditview.
38 When using one of these, groff generates the intermediate output for
39 this device and calls gxditview automatically for viewing.
40 -X produces good results only with -Tps, -TX75, -TX75-12, -TX100, and
42 -TX100-12. The default resolution for previewing -Tps output is 75dpi;
43 this can be changed with the -resolution option.
44 While gxditview is running, the left mouse button brings up a menu with
46 several entries.
47 Next Page Display the next page.
49 Previous Page
51 Display the previous page.
52 Select Page Select a particular numbered page specified by a dialog
54 box.
55 Print Print the groff intermediate output using a command speci‐
57 fied by a dialog box. The default command initially dis‐
58 played is controlled by the printCommand application re‐
59 source, and by the -printCommand option.
60 Open Open for display a new file specified by a dialog box.
62 The file should contain groff intermediate output. If the
63 filename starts with a bar or pipe symbol, “|” it will be
64 interpreted as a command from which to read.
65 Quit Exit from gxditview.
67 The menu entries correspond to actions with similar but not identical
69 names, which can also be accessed with keyboard accelerators. The n,
70 Space, Return, and Next (PgDn) keys are bound to the NextPage action.
71 The p, b, BackSpace, Delete, and Prior (PgUp) keys are bound to the
72 PreviousPage action. The g key is bound to the SelectPage action. The
73 o key is bound to the OpenFile action. The q key is bound to the Quit
74 action. The r key is bound to a Rerasterize action which rereads the
75 current file, and redisplays the current page; if the current file is a
76 command, the command will be re-executed. Vertical scrolling can be
77 done with the k and j keys; horizontal scrolling is bound to the h and
78 l keys. The arrow keys (up, down, left, and right) are also bound to
79 the obvious scrolling actions.
80 The paperlength and paperwidth commands in the DESC file describing a
82 groff output device specify the length and width in machine units of
83 the virtual page displayed by gxditview; see groff_font(5).
84 X defaults
86 This program uses the Dvi widget from the X Toolkit. It understands
87 all of the core resource names and classes as well as:
88 width (class Width)
90 Specifies the width of the window.
91 height (class Height)
93 Specifies the height of the window.
94 foreground (class Foreground)
96 Specifies the default foreground color.
97 font (class Font)
99 Specifies the font to be used for error messages.
100 fontMap (class FontMap)
102 Specifies the mapping from groff font names to X font names.
103 This must be a string containing a sequence of lines. Each line
104 contains two whitespace-separated fields: firstly the groff font
105 name, and secondly the XLFD (X Logical Font Description). The
106 default is shown in subsection “Default font map” below.
107 Default font map
109 XLFDs are long and unwieldy, so some lines are shown broken and in‐
110 dented below.

146 gxditview accepts all of the standard X Toolkit command-line options
148 along with the additional options listed below.
149 -page This option specifies the page number of the document to be dis‐
151 played.
152 -backingStore backing-store-type
154 Because redisplay of the groff intermediate output window can
155 take a perceiptible amount of time, this option causes the
156 server to save the window contents so that when it is scrolled
157 around the viewport, the window is painted from contents saved
158 in backing store. backing-store-type can be one of Always,
159 WhenMapped or NotUseful.
160 -printCommand command
162 The default command displayed in the dialog box for the Print
163 menu entry will be command.
164 -resolution res
166 The groff intermediate output file will be displayed at a reso‐
167 lution of res dots per inch, unless the DESC file contains the
168 X11 command, in which case the device resolution will be used.
169 This corresponds to the Dvi widget's resolution resource. The
170 default is 75.
171 -filename string
173 The default filename displayed in the dialog box for the Open
174 menu entry will be string. This can be either a filename, or a
175 command starting with “|”.
176 The following standard X Toolkit command-line arguments are commonly
178 used with gxditview.
179 -bg color
181 This option specifies the color to use for the background of the
182 window. The default is “white”.
183 -bd color
185 This option specifies the color to use for the border of the
186 window. The default is “black”.
187 -bw number
189 This option specifies the width in pixels of the border sur‐
190 rounding the window.
191 -fg color
193 This option specifies the color to use for displaying text. The
194 default is “black”.
195 -fn font
197 This option specifies the font to be used for displaying widget
198 text. The default is “fixed”.
199 -rv This option indicates that reverse video should be simulated by
201 swapping the foreground and background colors.
202 -geometry geometry
204 This option specifies the preferred size and position of the
205 window.
206 -display host:display
208 This option specifies the X server to contact.
209 -xrm resourcestring
211 This option specifies a resource string to be used.
212
214 GROFF_FONT_PATH
215 A list of directories in which to seek the selected output de‐
216 vice's directory of device and font description files. See
217 troff(1) and groff_font(5).
218
220 /usr/share/X11/app-defaults/GXditview
221 /usr/share/X11/app-defaults/GXditview-color
222 define X application defaults for gxditview. Users can override
223 these values in the .Xdefaults file, normally located in the
224 user's home directory. See appres(1) and xrdb(1).
225 /usr/share/groff/1.23.0/font/devX100/DESC
227 describes the X100 output device.
228 /usr/share/groff/1.23.0/font/devX100/F
230 describes the font known as F on device X100.
231 /usr/share/groff/1.23.0/font/devX100-12/DESC
233 describes the X100-12 output device.
234 /usr/share/groff/1.23.0/font/devX100-12/F
236 describes the font known as F on device X100-12.
237 /usr/share/groff/1.23.0/font/devX75/DESC
239 describes the X75 output device.
240 /usr/share/groff/1.23.0/font/devX75/F
242 describes the font known as F on device X75.
243 /usr/share/groff/1.23.0/font/devX75-12/DESC
245 describes the X75-12 output device.
246 /usr/share/groff/1.23.0/font/devX75-12/F
248 describes the font known as F on device X75-12.
249 /usr/share/groff/1.23.0/tmac/X.tmac
251 defines macros for use with the X100, X100-12, X75, and X75-12
252 output devices. It is automatically loaded by troffrc when any
253 of those output devices is selected.
254 /usr/share/groff/1.23.0/tmac/Xps.tmac
256 sets up troff to use gxditview as a previewer for device-inde‐
257 pendent output targeting the ps output device. It is automati‐
258 cally loaded by troffrc when troff is given the options -X and
259 -Tps.
260
262 The following command views this man page with a base point size of 12.
263 groff -TX100-12 -man gxditview.1
265 The quality of the result depends mainly on the chosen point size and
267 display resolution; for rapid previewing, however, something like
268 groff -X -P-resolution -P100 document
269 yields acceptable results.

272 gxditview and its predecessor xditview were written by Keith Packard
273 (MIT X Consortium), Richard L. Hyde (Purdue), David Slattengren (Berke‐
274 ley), Malcolm Slaney (Schlumberger Palo Alto Research), Mark Moraes
275 (University of Toronto), and James Clark.
276 This program is derived from xditview; portions of xditview originated
278 in xtroff, which was derived from suntroff.
