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\
I -*-times-medium-i-normal--*-*-*-*-*-*-iso8859-1\n\
B -*-times-bold-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.
