xditview - display ditroff output
xditview [ -toolkitoption ... ] [ -option ... ] [
  filename ]
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.
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.
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:

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.
