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.
