gxditview - display groff intermediate output files
gxditview [-toolkitoption ...] [-option ...] [filename]
The gxditview program displays the groff intermediate output, see
groff_out(5), on an X display. It uses the standard X11 fonts, so it
does not require access to the server machine for font loading. There
are several ways to use gxditview.
The groff intermediate output can be generated by groff -Z. This can
be viewed by explicity calling gxditview filename. If filename is -,
gxditview will read the standard input; filename cannot be omitted.
The groff intermediate output is different for all devices. gxditview
can view it for all devices, but the quality is device dependent.
The best results are achieved with the X* devices for groff's option
-T. There are four X* devices: -TX75, -TX75-12, -TX100, -TX100-12.
They differ by the X resolution (75dpi or 100dpi) and the used base
font size (10pt or 12pt). They are especially built for gxditview.
When using one of them groff generates the intermediate output for this
device and calls gxditview automatically for viewing. For example, to
view this man page with a base resolution of 12pt, say
groff -TX100-12 -man -rS12 gxditview.1
(option -rSXX is documented in the groff_man(7) man page).
groff's option -X produces intermediate output for the Postscript
device and subsequently uses gxditview as a viewer for it. The quality
of the result depends mainly on the chosen point size and display
resolution; for rapid previewing, however, something like
groff -X -P-resolution -P100 document
yields acceptable results.
During the run of gxditview, the left mouse button brings up a menu
with the following entries:
Display the next page.
Display the previous page.
Select a particular numbered page specified by a dialog box.
Print Print the groff intermediate output using a command specified
by a dialog box. The default command initially displayed is
controlled by the printCommand application resource, and by the
Open Open for display a new file specified by a dialog box. The
file should contain some groff intermediate output. If the
filename starts with | it will be taken to be a command to read
Quit Exit from gxditview.
The n, Space, Return, and Next (PgDn) keys are bound to the Next Page
action. The p, b, BackSpace, Delete, and Prior (PgUp) keys are bound
to the Previous Page action. The g key is bound to the SelectPage
action. The o key is bound to the OpenFile action. The q key is bound
to the Quit action. The r key is bound to the Rerasterize action which
rereads the current file, and redisplays the current page; if the
current file is a command, the command will be reexecuted. Vertical
scrolling can be done with the k and j keys; horizontal scrolling is
bound to the h and l keys. The arrow keys (up, down, left, and right)
are also bound to the obvious scrolling actions.
The paperlength and paperwidth commands in the DESC file specify the
length and width in machine units of the virtual page displayed by
The gxditview program accepts all of the standard X Toolkit command
line options along with the additional options listed below:
-help This option indicates that a brief summary of the allowed
options should be printed.
-page This option specifies the page number of the document to be
Redisplay of the groff intermediate output window can take up
to a second or so, this option causes the server to save the
window contents so that when it is scrolled around the
viewport, the window is painted from contents saved in backing
store. backing-store-type can be one of Always, WhenMapped or
The default command displayed in the dialog box for the Print
menu entry will be command.
The groff intermediate output file will be displayed at a
resolution of res dpi, unless the DESC file contains the X11
command, in which case the device resolution will be used.
This corresponds to the Dvi widget's resolution resource. The
default is 75.
The default filename displayed in the dialog box for the Open
menu entry will be string. This can be either a filename, or a
command starting with |.
The following standard X Toolkit command line arguments are commonly
used with gxditview:
This option specifies the color to use for the background of
the window. The default is white.
This option specifies the color to use for the border of the
window. The default is black.
This option specifies the width in pixels of the border
surrounding the window.
This option specifies the color to use for displaying text.
The default is black.
This option specifies the font to be used for displaying widget
text. The default is fixed.
-rv This option indicates that reverse video should be simulated by
swapping the foreground and background colors.
This option specifies the preferred size and position of the
This option specifies the X server to contact.
This option specifies a resource string to be used.
This program uses the Dvi widget in the X Toolkit. It understands all
of the core resource names and classes as well as:
width (class Width)
Specifies the width of the window.
height (class Height)
Specifies the height of the window.
foreground (class Foreground)
Specifies the default foreground color.
font (class Font)
Specifies the font to be used for error messages.
fontMap (class FontMap)
Specifies the mapping from groff font names to X font names.
This must be a string containing a sequence of lines. Each
line contains two whitespace separated fields: first the groff
font name, and secondly the X font name. The default is

these values in the .Xdefaults file, normally located in the
user's home directory. See xrdb(1) and appres(1) for more.

This program is derived from xditview; portions of xditview originated
in xtroff which was derived from suntroff.
