<title>What is &gwenview;</title>

<para>
&gwenview; is a fast and easy to use image and video viewer.
</para>

 <para>
&gwenview; features two main modes: Browse and View. Both modes can be used
in a normal application window and Full Screen. Browse Mode
lets you navigate through your computer showing thumbnails of your images, View
Mode lets you view images one at a time, and Full Screen lets you make quick
slideshows.  There is also a start screen that displays a list of recently opened
folders and &URL;s as well as your places and tags.
</para>

<para>Image loading is handled by the &Qt; library, so &gwenview; supports all
image formats your &Qt; installation supports. &gwenview; correctly displays images
with an alpha channel (transparency) as well as animations.</para>

<para>&gwenview; supports the displaying and editing of EXIF comments in JPEG
images. Lossless JPEG transforms such as rotations and mirroring are also supported.</para>

<para>&gwenview; can read embedded color profiles from PNG and JPEG files.
It can use the image color profile together with the display color profile
to output correct colors on the screen.</para>

<para>The slider at the bottom right allows you to change the size of the images.
You can also filter the images by filename, date, tag or rating using the box on the
lower left. The toolbar appears in both Browse mode as well as View

<sect1 id='view_mode'><title>View Mode</title>
<para>View Mode displays full-size images.  The same
<link linkend="sidebar">sidebar</link> available in Browse Mode is displayed on
the left. At the bottom, there is the Thumbnail Bar, which allows you to scroll
through the images in the current folder. The Thumbnail Bar can be unfolded by
clicking on the <guibutton>Show Thumbnails</guibutton> button. Clicking again will
fold it. To change the size of the thumbnails move the splitter with the &LMB;.</para>

<para>View Mode supports viewing multiple images side-by-side.  You may select
multiple images in Browse Mode before switching to View Mode, or you may click the
<guibutton>+</guibutton> button that appears when hovering over images in the
Thumbnail Bar to add a pane displaying that image.  A <guibutton>-</guibutton> will
then appear that will permit you to remove its pane.</para>

<para>When multiple images are displayed, a small toolbar appears below each image
that permits you to delete the image or remove its pane.  You may perform zoom operations
independently for each image, or synchronize them.  Toggle this by checking the
<guilabel>Synchronize</guilabel> to the left of the zoom slider or by pressing
<keycombo action="simul">&Ctrl;<keycap>Y</keycap></keycombo>.  You can switch images
by clicking on their pane, or using your keyboard.  To switch to the image on the
right, press <keycombo action="simul">&Tab;</keycombo>.  To switch to the image
on the left, press <keycombo action="simul">&Shift;&Tab;</keycombo>.</para>

<para>The slider at the bottom right controls the zoom of the image. The
<guibutton>Fit</guibutton>, <guibutton>Fill</guibutton> and <guibutton>100%</guibutton>
buttons are next to the zoom slider and are three preset zoom levels. The
<guibutton>Fit</guibutton> button zooms the current image to fit the size
of the window, the <guibutton>Fill</guibutton> button zooms the image to fill the window 
by fitting width or height and the <guibutton>100%</guibutton> button zooms the image to
the actual pixel size. The shortcut <keycap>F</keycap> toggles between <guibutton>Fit</guibutton> mode and <guibutton>100%</guibutton>, pressing <keycombo action="simul">&Shift;<keycap>F</keycap></keycombo> will toggle <guibutton>Fill</guibutton> respectively.</para>

<para>When an image is in zoom-to-fit mode, you can go to the previous and next
image with the arrow keys. When you zoom in, arrow keys are used to scroll the image.
This is very similar to the behavior provided by phones or digital cameras.</para>

<para>When an image is zoomed in, a bird's eye view appears and lets you scroll
the image using the mouse and the arrow keys. The bird's eye view automatically hides
itself after a short delay, showing back only while zooming or scrolling. The bird's eye view
can be disabled from the right click context menu or from <menuchoice><guimenu>View</guimenu><guimenuitem>Show Bird's Eye View When Zoomed In</guimenuitem></menuchoice></para>

<para>You can define what happens when going to image B after having zoomed in on an area of image A using the options in the <guilabel>Zoom mode</guilabel> group on the <guimenuitem>Image View</guimenuitem> page of the &gwenview; configuration window which can be reached using the <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure &gwenview;...</guimenuitem></menuchoice>.</para>

    <listitem><para>If set to <guilabel>Keep same zoom and position</guilabel>, all images share the same zoom and position: image B is set to the same zoom parameters as image A (and if these are changed, image A will then be displayed with the updated zoom and position).</para></listitem>
    <listitem><para>If set to <guilabel>Per image zoom and position</guilabel>, all images remember their own zoom and position: image B is initially set to the same zoom parameters as image A, but will then remember its own zoom and position (if these are changed, image A will <emphasis>not</emphasis> be displayed with the updated zoom and position).</para></listitem>
</itemizedlist>

<tip><para>You can start directly in View mode by starting &gwenview; from a
context menu like <guimenuitem>Open With</guimenuitem> in another program or by
launching it from the command line with an image as an argument.</para> </tip>

<para>The following additional image operations are available only in View Mode:</para>

  <guimenuitem>Crop</guimenuitem>
 </menuchoice>:
 This operation lets you discard parts of the image you don't want.
</para>
<para>
    You can access the advanced cropping parameters by ticking <guilabel>Advanced settings</guilabel> check box on the bottom popup pane. Use the corresponding fields to tune up the cropping operation.
</para>
<para>
    It is also possible to adjust the cropped area by dragging the gray square handles on the borders of the image. You can move the cropped area by clicking and holding the &LMB; and drag it with the mouse pointer.
</para>
<para>
    Press the <guibutton>Crop</guibutton> button to see the results when you are ready. Use the upper popup pane to save the results or undo/redo the operation.
