NAME
       gxditview - display groff intermediate output files

SYNOPSIS
       gxditview [-toolkitoption ...] [-option ...] [filename]

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 explic-
       ity 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 applica-
	       tion 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; hori-
       zontal 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 fore-
	       ground 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  sepa-
	       rated  fields:  first  the  groff  font	name,  and secondly the X font name.  The
	       default is
	       "\
