gxditview - display gtroff output files

gxditview [-toolkitoption ...] [-option ...] [filename]

The gxditview program displays gtroff output on an X display. It uses the standard X11 fonts, so it does not require access to the server machine for font loading.

If filename is -, gxditview will read the standard input.

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 gtroff 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 gtroff 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.

Gxditview 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 gtroff output window can take upto 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 gtroff 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 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
