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 coordi-
       nates 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 suppesses 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,  When-
	       Mapped 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

	       I    -*-times-medium-i-normal--*-*-*-*-*-*-iso8859-1

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.
