## About this Document

This is version &rev; of the &Yap; User's Guide. It corresponds to &Yap; &yaprev; as at &date;.

## About &Yap;

This section is borrowed from the XDVI help file.

You use &Yap; (Yet Another Previewer) to view &DVI; files, such as are produced by &TeX;.

&Yap; has the capability of showing the file shrunken by various (integer) factors, and also has a magnifying glass which allows one to see a small part of the unshrunk image momentarily.

Before displaying any page or part thereof, &Yap; checks to see if the &DVI; file has changed since the last time it was displayed. If this is the case, then &Yap; will reinitialize itself for the modified &DVI; file.

## How to Open a File

There are several ways to open a file:

- by double-clicking a &DVI; file icon in the Windows shell (Explorer)

- by dragging a &DVI; file icon to the &Yap; application window

- by specifying a file name on the &Yap; command-line (see ).

- by clicking Open... on the File menu.

- by clicking an MRU (most recently used} item on the File menu.

You can open more than one file with a single instance of &Yap;.

## Viewing &DVI; Files

### Render Methods

&Yap; supports two render methods:

Pk

  The &DVI; file is rendered using packed raster fonts. This is the traditional method to render &DVI; files.

Dvips

  The &DVI; file is rendered using &Dvips;/&Ghostscript;. This render method is suitable for &DVI; files which contain &PostScript; instructions. (e.g., rotated text and graphics).

  PostScript specials

The render method for the viewed &DVI; file can be chosen in the View menu ().

The default render method can be chosen on the Display property page ().

### Presenting Documents in Full Screen View

In Full Screen view, &DVI; pages fill the entire screen; the menu bar, tool bar and status bar are hidden. Full Screen view is often used for presentations. The pointer remains active in Full Screen view so that you can click links. You can use keybord shortcuts () for navigational and magnification commands.

To present a document in Full Screen view, click Full Screen on the View menu. To exit Full Screen view, press Escape.
