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
               "\
