NAME

       xditview - display ditroff output

SYNOPSIS

       xditview [ -toolkitoption ... ] [ -option ... ] [ filename ]

DESCRIPTION

       The  xditview  program  displays  ditroff  output  on  an  X  display.   It  uses  no special metrics and
       automatically converts the printer coordinates into screen coordinates; using the  user-specified  screen
       resolution,  rather  than  the actual resolution so that the appropriate fonts can be found.  If ``-'' is
       given as the filename, xditview reads from standard input.  If ``|'' is the first character of  filename,
       xditview forks sh to run the rest of the ``file name'' and uses the standard output of that command.

OPTIONS

       Xditview  accepts  all  of  the standard X Toolkit command line options along with the additional options
       listed below:

       -page page-number
               This option specifies the page number of the document to be displayed at start up time.

       -resolution screen-resolution
               This specifies the desired screen resolution to use; fonts will  be  opened  by  requesting  this
               resolution field in the XLFD names.

       -noPolyText
               Some  X  servers  incorrectly  implement PolyText with multiple strings per request.  This option
               suppresses the use of this feature in xditview.

       -backingStore backing-store-type
               Redisplay 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.

       The following standard X Toolkit command line arguments are commonly used with xditview:

       -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 a Dvi widget.  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)
               To  associate  the ditroff fonts with appropriate X fonts, this string resource contains a set of
               new-line separated specifications, each of which consists of a ditroff name, some white space and
               an  XLFD  pattern  with  * characters in appropriate places to allow all sizes to be listed.  The
               default fontMap is:

               R    -*-times-medium-r-normal--*-*-*-*-*-*-iso8859-1\n\

USING XDITVIEW WITH DITROFF

       You can use any ditroff output file with xditview, although files which use the fonts appropriate to  the
       fontMap will look more accurate on the screen.  On servers which support scaled fonts, all requested font
       sizes will be accurately reflected on the screen; for servers which do not support scaled  xditview  will
       use the closest font from the same family.
