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 explicitly 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 resolu‐ tion of 12pt, say **groff** **-TX100-12** **-man** **-rS12** **gxditview.1** (option **-rS**_XX_ is documented in the **groff**___**[man**(7)](https://www.chedong.com/phpMan.php/man/man/7/markdown) 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 en‐ tries: ### 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 re‐ source, 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 ma‐ chine 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 ### -page ### -backingStore 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 The default command displayed in the dialog box for the **Print** menu entry will be _com__‐ _mand_. ### -resolution The _groff_ _intermediate_ _output_ file will be displayed at a resolution of _res_ dpi, un‐ less 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 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 This option specifies the color to use for the background of the window. The default is _white_. ### -bd This option specifies the color to use for the border of the window. The default is _black_. ### -bw This option specifies the width in pixels of the border surrounding the window. ### -fg This option specifies the color to use for displaying text. The default is _black_. ### -fn This option specifies the font to be used for displaying widget text. The default is _fixed_. ### -rv ground and background colors. ### -geometry This option specifies the preferred size and position of the window. ### -display This option specifies the X server to contact. ### -xrm 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.
