<h3><a name="preferences">Preferences</a></h3>
<p> When you run the plug-in for the first
time you should customize some of the settings. To do this by
clicking on "Preferences" in the Welcome dialog:</p>
<p class=image><img src=welcome.gif></p>
<p style="text-indent: 0pt">or by right-clicking anywhere in a DjVu document and selecting <b>Preferences</b>
in the popup menu:</p>
<p class=image><img src="popup-preferences.gif"></p>
<p>This window will appear:</p>
<p class=image><IMG src="preferences.gif" ></p>
<p>In the Display Preferences, drag the slider
until all four squares look approximately the same.</p>
<p>On fast machines, disable "Favor fast magnifications for 'Fit' resolutions".
On slow machines, enable "Draw using simple border". If
you have at least 64MB of memory, enable "Print with highest quality".

<A href="#top">Go to top</A>
</p>
<!--------------------------------------------------------------------------->
<h3><a NAME="scrolling"></a>Scrolling</h3>
<p>DjVu documents, when zoomed to sizes larger than the display window, can
be scrolled whenever you see the hand cursor (<img align=top src="hand.gif">) by clicking
on the document, moving the mouse, then unclicking. You can also scroll the
document using the scroll bars at the right and bottom of the document, or by using
Up, Down, Left, and Right <a href="refs.html#keyboard_shortcuts">keyboard shortcuts</a>.
<h3><a NAME="toolbar"></a>Popup toolbar</h3>
<p>The popup toolbar is located at the bottom of the plug-in's
window and appears as
follows:
<p class=image><IMG src="toolbar.gif" ></p>
<p class=right>
<A href="#top">Go to top</A>
</p>
<!--------------------------------------------------------------------------->
<h3><a NAME="modes"></a>Display mode</h3>
<p>Most DjVu files contain images stored in more than
one <A href="refs.html#chunk_names">layer</A>. There may be several background layers,
a mask layer, and a foreground layer. By switching between different display
modes, one can see what is stored in each layer.</p>
<p>In order to change the display mode, select the desired mode from the <b>Display</b>
item on toolbar.</p>
<p class=right>
<A href="#top">Go to top</A>
</p>
<!--------------------------------------------------------------------------->
<h3><a NAME="zoom"></a>Zoom</h3>
<p>The zoom factor refers to the magnification of the physical dimensions
of the image.
<p>Besides numerical zoom, four more zoom types are recognized:</p>
<div class="table">
<table BORDER=1 CELLSPACING=0 CELLPADDING=6>
<tr>
<th>Zoom</th>
<th>Description</th>
</tr>
<tr class="row1">
<td><b>Fit Width</b></td>
<td>
<p>Scales the image to fit the width of the window.</p>
<p>Note: On slow machines, the scaling is not continuously variable.</p>
</td>
</tr>
<tr class="row2">
<td><b>Fit Page</b></td>
<td>
<p>Scales the image to fit the window.</p>
<p>Note: On slow machines, the scaling is not continuously variable</p>
</td>
</tr>
<tr class="row1">
<td><b>One-to-One</b></td>
<td><p>The image is scaled to be displayed in pixel-to-pixel mode when every
pixel of the original image corresponds to one pixel on the screen.
</p></td>
</tr>
<tr class="row2">
<td><b>Stretch</b></td>
<td><p>The image is stretched to fit the window precisely.</p></td>
</tr>
</table>
</div>
<p>In order to change the zoom factor, you can select the <b>Zoom</b>
item from the toolbar or popup menu.
<p>There are also
<a href="refs.html#keyboard_shortcuts">keyboard shortcuts</a> available that directly set the zoom factor.
<p class=right>

</p>
<!--------------------------------------------------------------------------->
<h3><a NAME="navigation"></a>Navigation</h3>
<!--------------------------------------------------------------------------->
<p>If you view a multipage DjVu document you will need
a way to navigate through it, that is to go from page to page. There are
two ways described here to achieve it.
<h4><a NAME="nav_keyboard"></a>Navigation using Keyboard Shortcuts</h4>
<p>This is the most useful when you look through the
document page by page. The following hot keys are enabled:</p>
<div class="table">
<table BORDER =1 CELLSPACING=0 CELLPADDING=6>
<tr>
<th>Key</th>
<th>Action</th>
</tr>
<tr class="row1">
<td><b>Page Down</b>, <b>Page Up</b></td>
<td><p>Go to the end/beginning of the page. If already there, switch to the
next/previous page if possible.</p></td>
</tr>
<tr class="row2">
<td><b>Space</b></td>
<td><p>Switch to the next page.</p></td>
</tr>
<tr class="row1">
<td><b>Backspace</b></td>
<td><p>Switch to the previous page.</p></td>
</tr>
<tr class="row2">
<td><b>Home</b></td>
<td><p>Move to the beginning of the document.</p></td>
</tr>
<tr class="row1">
<td><b>End</b></td>
<td><p>Move to the end of the document.</p></td>
</tr>
</table>
</div>
<p>
Here is
<a href="refs.html#keyboard_shortcuts">a complete list of keyboard shortcuts</a>.

<A href="#top">Go to top</A>
</p>
<!--------------------------------------------------------------------------->
<h4><a NAME="nav_toolbar"></a>Navigation using the Popup Toolbar</h4>
<p>Here you can use six buttons from the toolbar to go to
the previous page, next page, plus/minus 10 pages, to the beginning and to the
end of the document. In addition, you can select the page you want to see from
the combo box directly.
<p class=right>
<A href="#top">Go to top</A>
</p>
<h3><a NAME="saving"></a>Saving</h3>
<p>The Save icon on the <a href="#toolbar">popup toolbar</a> saves the
whole document to a file.</p>
<p class=right>
<A href="#top">Go to top</A>
</p>
<h3><a NAME="printing"></a>Printing</h3>
<p>
Selecting the Print option from the DjVu
toolbar displays a Print dialog box.</p>
<p>NOTE: The display mode affects what is being printed, so if
you want the all document layers to be printed, make sure you are in the
<b>Color</b> display mode. The zoom mode does not affect printing.</p>
<p>NOTE: The DjVu plug-In does NOT use the Print command
that is found on the
main browser menu bar to print DjVu images. Instead, in order to print a loaded
image DjVu, click on the print icon on
the <a href="#toolbar">DjVu popup toolbar</a>.</p>
