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 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, 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.
