NAME
gxditview - display groff intermediate output files
SYNOPSIS
gxditview [-toolkitoption ...] [-option ...] [filename]
DESCRIPTION
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 explicity 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 not always good.
The best result is 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.
groff's option -X should be considered obsolete today; it produces
intermediate output for Postscript and uses gxditview as a viewer for
it, but with a bad quality. Simply don't use it.
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 and Return keys are bound to the Next Page action. The p,
BackSpace and Delete keys are bound to the Previous Page 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.
The paperlength and paperwidth commands in the DESC file specify the
length and width in machine units of the virtual page displayed by
gxditview.
OPTIONS
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 view-
port, 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 reso-
lution of res dpi, unless the DESC file contains the X11 com-
mand, 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 sur-
rounding 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 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
