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:
R -*-times-medium-r-normal--*-*-*-*-*-*-iso8859-1\n\

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.
