The
gxditview program displays the
groff intermediate
output, see
groff_out(5), on an X display. It uses the
standard X11 fonts, so it does not require access to the server machine for
font loading. There are several ways to use
gxditview.
The
groff intermediate output can be generated by
groff -Z.
This can be viewed by explicitly calling
gxditview filename. If
filename is
-,
gxditview will read the standard input;
filename cannot be omitted. The
groff intermediate output is
different for all devices.
gxditview can view it for all devices, but
the quality is device dependent.
The best results are achieved with the
X* devices for
groff's
option
-T. There are four
X* devices:
-TX75,
-TX75-12,
-TX100,
-TX100-12. They differ by the
X resolution (75dpi or 100dpi) and the used base font size (10pt or
12pt). They are especially built for
gxditview. When using one of them
groff generates the
intermediate output for this device and
calls
gxditview automatically for viewing. For example, to view this
man page with a base resolution of 12pt, say
- groff -TX100-12 -man -rS12 gxditview.1
(option
-rSXX is documented in the
groff_man(7) man page).
groff's option
-X produces
intermediate output for the
PostScript device and subsequently uses
gxditview as a viewer
for it. The quality of the result depends mainly on the chosen point size and
display resolution; for rapid previewing, however, something like
-
groff -X -P-resolution -P100 document
yields acceptable results.
During the run of
gxditview, the left mouse button brings up a menu with
the following entries:
- Next Page
- Display the next page.
- Previous Page
- Display the previous page.
- Select Page
- Select a particular numbered page specified by a dialog
box.
- Print
- Print the groff intermediate output using a command
specified by a dialog box. The default command initially displayed is
controlled by the printCommand application resource, and by the
-printCommand option.
- Open
- Open for display a new file specified by a dialog box. The
file should contain some groff intermediate output. If the
filename starts with | it will be taken to be a command to read
from.
- Quit
- Exit from gxditview.
The
n,
Space,
Return, and
Next (
PgDn) keys
are bound to the
Next Page action. The
p,
b,
BackSpace,
Delete, and
Prior (
PgUp) keys are bound
to the
Previous Page action. The
g key is bound to the
SelectPage action. The
o key is bound to the
OpenFile
action. The
q key is bound to the
Quit action. The
r key
is bound to the
Rerasterize action which rereads the current file, and
redisplays the current page; if the current file is a command, the command
will be reexecuted. Vertical scrolling can be done with the
k and
j keys; horizontal scrolling is bound to the
h and
l
keys. The arrow keys (
up,
down,
left, and
right)
are also bound to the obvious scrolling actions.
The
paperlength and
paperwidth commands in the
DESC file
specify the length and width in machine units of the virtual page displayed by
gxditview.
The
gxditview program accepts all of the standard X Toolkit
command-line options along with the additional options listed below:
- -help
- This option indicates that a brief summary of the allowed
options should be printed.
- -page
- This option specifies the page number of the document to be
displayed.
-
-backingStore backing-store-type
- Redisplay of the groff intermediate output window
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.
-
-printCommand command
- The default command displayed in the dialog box for the
Print menu entry will be command.
-
-resolution res
- The groff intermediate output file will be displayed
at a resolution of res dpi, unless the DESC file contains
the X11 command, in which case the device resolution will be used.
This corresponds to the Dvi widget's resolution resource.
The default is 75.
-
-filename string
- The default filename displayed in the dialog box for the
Open menu entry will be string. This can be either a
filename, or a command starting with |.
The following standard X Toolkit command-line arguments are commonly used
with
gxditview:
-
-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 the
Dvi widget in the X Toolkit. 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)
- Specifies the mapping from groff font names to
X font names. This must be a string containing a sequence of lines.
Each line contains two whitespace separated fields: first the groff
font name, and secondly the X font name. The default is

- GROFF_FONT_PATH
- A list of directories in which to search for the
devname directory in addition to the default ones. See
troff(1) and groff_font(5) for more details.
- /etc/X11/app-defaults/GXditview
-
/etc/X11/app-defaults/GXditview-color The default
resource files of gxditview. Users should override these values in
the .Xdefaults file, normally located in the user's home directory.

xditview were written by Keith
