DESCRIPTION

       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 gxditview.

OPTIONS

       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 displayed.

       -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 window.

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

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

X DEFAULTS

       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
               "\
