.SH DESCRIPTION
.\" ====================================================================
.
The
.B \%gxditview
program displays the
.I groff intermediate
.IR output ,
see
.BR 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
.BR \%gxditview .
.
.
.PP
The
.I groff intermediate output
can be generated by
.BR groff\~\-Z .
This can be viewed by explicitly calling
.B \%gxditview
.IR \%filename .
.
If
.I filename
is
.BR \- ,
.B \%gxditview
will read the standard input;
.I \%filename
cannot be omitted.
.
The
.I groff intermediate output
is different for all devices.
.
.B \%gxditview
can view it for all devices, but the quality is device dependent.
.
.
.PP
The best results are achieved with the
.BR X *
devices for
.BR groff 's
option
.BR \-T .
.
There are four
.BR X *
devices:
.BR \%\-TX75 ,
.BR \%\-TX75\-12 ,
.BR \%\-TX100 ,
.BR \%\-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
.BR \%gxditview .
.
When using one of them
.B groff
generates the
.I intermediate output
for this device and calls
.B \%gxditview
automatically for viewing.
.
For example, to view this man page with a base resolution of 12pt, say
.
.IP
.B groff \-TX100\-12 \-man \-rS12 gxditview.1
.
.
.PP
(option
.BI \-rS XX
is documented in the
.BR groff_man (7)
man page).
.
.
.PP
.BR groff 's
option
.B \-X
produces
.I intermediate output
for the
.I PostScript
device and subsequently uses
.B \%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
.
.IP
.BI "groff \-X \-P\-resolution \-P100 " document
.
.
.PP
yields acceptable results.
.
.
.PP
During the run of
.BR \%gxditview ,
the left mouse button brings up a menu with the following entries:
.
.TP 8
.B "Next Page"
Display the next page.
.
.TP
.B "Previous Page"
Display the previous page.
.
.TP
.B "Select Page"
Select a particular numbered page specified by a dialog box.
.
.TP
.B Print
Print the
.I groff intermediate output
using a command specified by a dialog box.
.
The default command initially displayed is controlled by the
.B printCommand
application resource, and by the
.B \-printCommand
option.
.
.TP
.B Open
Open for display a new file specified by a dialog box.
.
The file should contain some
.I groff intermediate
.IR output .
.
If the filename starts with
.B |
it will be taken to be a command to read from.
.
.TP
.B Quit
Exit from
.BR \%gxditview .
.
.
.PP
The
.IR n ,
.IR Space ,
.IR Return ,
and
.I Next
.RI ( PgDn )
keys are bound to the
.B Next\ Page
action.
.
The
.IR p ,
.IR b ,
.IR BackSpace ,
.IR Delete ,
and
.I Prior
.RI ( PgUp )
keys are bound to the
.B Previous\ Page
action.
.
The
.I g
key is bound to the
.B SelectPage
action.
.
The
.I o
key is bound to the
.B OpenFile
action.
.
The
.I q
key is bound to the
.B Quit
action.
.
The
.I r
key is bound to the
.B 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
.I k
and
.I j
keys;
horizontal scrolling is bound to the
.I h
and
.I l
keys.
.
The arrow keys
.RI ( up ,
.IR down ,
.IR left ,
and
.IR right )
are also bound to the obvious scrolling actions.
.
.
.PP
The
.B paperlength
and
.B paperwidth
commands in the
.I DESC
file specify the length and width in machine units of the virtual page
displayed by
.BR \%gxditview .
.
.
.\" ====================================================================
.SH OPTIONS
.\" ====================================================================
.
The
.B \%gxditview
program accepts all of the standard X\~Toolkit command-line options
along with the additional options listed below:
.
.TP 8
.B \-help
This option indicates that a brief summary of the allowed options should be
printed.
.
.TP
.B \-page
This option specifies the page number of the document to be displayed.
.
.TP
.BI \-backingStore\  backing-store-type
Redisplay of the
.I 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.
.
.I backing-store-type
can be one of
.BR Always ,
.B WhenMapped
or
.BR NotUseful .
.
.TP
.BI \-printCommand\  command
The default command displayed in the dialog box for the
.B Print
menu entry will be
.IR command .
.
.TP
.BI \-resolution\  res
The
.I groff intermediate output
file will be displayed at a resolution of
.I res
dpi, unless the
.I DESC
file contains the
.B X11
command, in which case the device resolution will be used.
.
This corresponds to the
.I Dvi
widget's

resource.
.
The default is 75.
.
.TP
.BI \-filename\  string
The default filename displayed in the dialog box for the
.B Open
