GXDITVIEW

NAME

SYNOPSIS

DESCRIPTION

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 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.  

OPTIONS

-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.
