17 The gxditview program displays the groff intermediate output, see
18 groff_out(5), on an X display. It uses the standard X11 fonts, so it
19 does not require access to the server machine for font loading. There
20 are several ways to use gxditview.
21 The groff intermediate output can be generated by groff -Z. This can
23 be viewed by explicitly calling gxditview filename. If filename is -,
24 gxditview will read the standard input; filename cannot be omitted.
25 The groff intermediate output is different for all devices. gxditview
26 can view it for all devices, but the quality is device dependent.
27 The best results are achieved with the X* devices for groff's option
29 -T. There are four X* devices: -TX75, -TX75-12, -TX100, -TX100-12.
30 They differ by the X resolution (75dpi or 100dpi) and the used base
31 font size (10pt or 12pt). They are especially built for gxditview.
32 When using one of them groff generates the intermediate output for this
33 device and calls gxditview automatically for viewing. For example, to
34 view this man page with a base resolution of 12pt, say
35 groff -TX100-12 -man -rS12 gxditview.1
37 (option -rSXX is documented in the groff_man(7) man page).
39 groff's option -X produces intermediate output for the PostScript de‐
41 vice and subsequently uses gxditview as a viewer for it. The quality
42 of the result depends mainly on the chosen point size and display reso‐
43 lution; for rapid previewing, however, something like
44 groff -X -P-resolution -P100 document
46 yields acceptable results.
48 During the run of gxditview, the left mouse button brings up a menu
50 with the following entries:
51 Next Page
53 Display the next page.
54 Previous Page
56 Display the previous page.
57 Select Page
59 Select a particular numbered page specified by a dialog box.
60 Print Print the groff intermediate output using a command specified
62 by a dialog box. The default command initially displayed is
63 controlled by the printCommand application resource, and by the
64 -printCommand option.
65 Open Open for display a new file specified by a dialog box. The
67 file should contain some groff intermediate output. If the
68 filename starts with | it will be taken to be a command to read
69 from.
70 Quit Exit from gxditview.
72 The n, Space, Return, and Next (PgDn) keys are bound to the Next Page
74 action. The p, b, BackSpace, Delete, and Prior (PgUp) keys are bound
75 to the Previous Page action. The g key is bound to the SelectPage ac‐
76 tion. The o key is bound to the OpenFile action. The q key is bound
77 to the Quit action. The r key is bound to the Rerasterize action which
78 rereads the current file, and redisplays the current page; if the cur‐
79 rent file is a command, the command will be reexecuted. Vertical
80 scrolling can be done with the k and j keys; horizontal scrolling is
81 bound to the h and l keys. The arrow keys (up, down, left, and right)
82 are also bound to the obvious scrolling actions.
83 The paperlength and paperwidth commands in the DESC file specify the
85 length and width in machine units of the virtual page displayed by
86 gxditview.
87
89 The gxditview program accepts all of the standard X Toolkit command-
90 line options along with the additional options listed below:
91 -help This option indicates that a brief summary of the allowed op‐
93 tions should be printed.
94 -page This option specifies the page number of the document to be
96 displayed.
97 -backingStore backing-store-type
99 Redisplay of the groff intermediate output window can take up
100 to a second or so, this option causes the server to save the
101 window contents so that when it is scrolled around the view‐
102 port, the window is painted from contents saved in backing
103 store. backing-store-type can be one of Always, WhenMapped or
104 NotUseful.
105 -printCommand command
107 The default command displayed in the dialog box for the Print
108 menu entry will be command.
109 -resolution res
111 The groff intermediate output file will be displayed at a reso‐
112 lution of res dpi, unless the DESC file contains the X11 com‐
113 mand, in which case the device resolution will be used. This
114 corresponds to the Dvi widget's resolution resource. The de‐
115 fault is 75.
116 -filename string
118 The default filename displayed in the dialog box for the Open
119 menu entry will be string. This can be either a filename, or a
120 command starting with |.
121 The following standard X Toolkit command-line arguments are commonly
123 used with gxditview:
124 -bg color
126 This option specifies the color to use for the background of
127 the window. The default is white.
128 -bd color
130 This option specifies the color to use for the border of the
131 window. The default is black.
132 -bw number
134 This option specifies the width in pixels of the border sur‐
135 rounding the window.
136 -fg color
138 This option specifies the color to use for displaying text.
139 The default is black.
140 -fn font
142 This option specifies the font to be used for displaying widget
143 text. The default is fixed.
144 -rv This option indicates that reverse video should be simulated by
146 swapping the foreground and background colors.
147 -geometry geometry
149 This option specifies the preferred size and position of the
150 window.
151 -display host:display
153 This option specifies the X server to contact.
154 -xrm resourcestring
156 This option specifies a resource string to be used.
157
159 This program uses the Dvi widget in the X Toolkit. It understands all
160 of the core resource names and classes as well as:
161 width (class Width)
163 Specifies the width of the window.
164 height (class Height)
166 Specifies the height of the window.
167 foreground (class Foreground)
169 Specifies the default foreground color.
170 font (class Font)
172 Specifies the font to be used for error messages.
173 fontMap (class FontMap)
175 Specifies the mapping from groff font names to X font names.
176 This must be a string containing a sequence of lines. Each
177 line contains two whitespace separated fields: first the groff
178 font name, and secondly the X font name. The default is
