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: .
8 "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 . . .
8 -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 | . . .
