Description         top

       gxditview interprets and displays the intermediate output format
       of groff(1) on an X11 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 intermediate output format of groff, documented in
       groff_out(5), is produced by troff or the -Z option to groff.  It
       can be viewed by explicitly calling “gxditview file”.  If the
       file operand is “-”, gxditview will read the standard input
       stream; file cannot be omitted.  The intermediate output format
       of groff is device-independent but not device-agnostic.
       gxditview can view it for all typesetter devices, but the quality
       is device-dependent.  gxditview will not display output for
       terminal (nroff) devices.

       The best results are achieved with the X* devices for groff's -T
       option, of which there are four: -TX75, -TX75-12, -TX100, and
       -TX100-12.  They differ by the X resolution (75 or 100 dots per
       inch) and the base point size (10 or 12 points).  They are
       especially built for gxditview.  When using one of these, groff
       generates the intermediate output for this device and calls
       gxditview automatically for viewing.

       -X produces good results only with -Tps, -TX75, -TX75-12, -TX100,
       and -TX100-12.  The default resolution for previewing -Tps output
       is 75dpi; this can be changed with the -resolution option.

       While gxditview is running, the left mouse button brings up a
       menu with several entries.

       Next Page
              Display the next page.

       Previous Page
              Display the previous page.

       Select Page
              Select a particular numbered page specified by a dialog

       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 groff intermediate output.  If the
              filename starts with a bar or pipe symbol, “|” it will be
              interpreted as a command from which to read.

       Quit   Exit from gxditview.

       The menu entries correspond to actions with similar but not
       identical names, which can also be accessed with keyboard
       accelerators.  The n, Space, Return, and Next (PgDn) keys are
       bound to the NextPage action.  The p, b, BackSpace, Delete, and
       Prior (PgUp) keys are bound to the PreviousPage 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 a Rerasterize action which rereads the current
       file, and redisplays the current page; if the current file is a
       command, the command will be re-executed.  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
       describing a groff output device specify the length and width in
       machine units of the virtual page displayed by gxditview; see

   X defaults
       This program uses the Dvi widget from the X Toolkit.  It
       understands all of the core resource names and classes as well

       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: firstly the groff font name, and secondly the XLFD
              (X Logical Font Description).  The default is shown in
              subsection “Default font map” below.

   Default font map
       XLFDs are long and unwieldy, so some lines are shown broken and
       indented below.

Options         top

       gxditview 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 displayed.

       -backingStore backing-store-type
              Because redisplay of the groff intermediate output window
              can take a perceiptible amount of time, 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 dots per inch, 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

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

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

       -xrm resourcestring
              This option specifies a resource string to be used.

Environment         top

              A list of directories in which to seek the selected output
              device's directory of device and font description files.
              See troff(1) and groff_font(5).

Files         top

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

Examples         top

       The following command views this man page with a base point size
       of 12.

              groff -TX100-12 -man gxditview.1

       The quality of the result depends mainly on the chosen point size
       and display resolution; for rapid previewing, however, something
              groff -X -P-resolution -P100 document
       yields acceptable results.
