       gxditview --help

       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 explicitly 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:

       Next Page
               Display the next page.

       Previous Page
               Display the previous page.

       Select 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
               -printCommand option.

       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 from.

       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

       -backingStore backing-store-type
               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 NotUseful.

       -printCommand command
               The default command displayed in the dialog box for the Print
               menu entry will be command.

       -resolution res
               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.

       -filename string
               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:

       -bg color
               This option specifies the color to use for the background of the
               window.  The default is white.

       -bd color
               This option specifies the color to use for the border of the
               window.  The default is black.

       -bw number
               This option specifies the width in pixels of the border
               surrounding the window.

       -fg color
               This option specifies the color to use for displaying text.  The
               default is black.

       -fn font
               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.

       -geometry geometry
               This option specifies the preferred size and position of the

       -display host:display
               This option specifies the X server to contact.

       -xrm resourcestring
               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

              The default resource files of gxditview.  Users should override
              these values in the .Xdefaults file, normally located in the
              user's home directory.  See xrdb(1) and appres(1) for more.

       gxditview and its predecessor xditview were written by Keith Packard (MIT
       X Consortium), Richard L. Hyde (Purdue), David Slattengren (Berkeley),
       Malcolm Slaney (Schlumberger Palo Alto Research), Mark Moraes (University
       of Toronto), and James Clark.
