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 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.
 

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
