  <title>The Viewer</title>
  <para>The reason for you to put all your images into &kphotoalbum;, and
spending hours after hours describing them, is of course that you at some
point want to look at them. For that purpose &kphotoalbum; has an viewer
capable of showing your images and videos. You open the viewer from the
thumbnail view as described in <xref
      linkend="chp-thumbnail-view"/>.</para>

  <para>The viewer can be seen in <xref linkend="fig-viewer"/>. The viewer
does of course show you the image, but in addition to that it also shows
you the information you specified for each image, including, who is on the
 images, where and when it was takes, &etc;
</para>

  <para>In case the info box is located on top of part of the images you actually
want to see, you can simply grab it with the mouse, and move it elsewhere
on the image. It is possible to configure what should be shown in the
info box, and of course whether it should be shown at all. All these
options are available by right clicking your mouse on the viewer. The
context menu can be seen in <xref linkend="fig-viewer-contextmenu"/>
below.</para>

  <para>Some of the words in the info box is underlines. If you click the
mouse on one of these words the browser (see <xref linkend="chp-browsing"/>)
will go into scope of that item. Thus if you click on <literal>Anne
Helene</literal> the browser will show you all images of Anne Helene, just
as it would have done if you selected <literal>People</literal> from the
root of the browser, and next selected <literal>Anne
Helene</literal>.</para>

<para>In the info box you can see a small button with the &kphotoalbum;
logo. Pressing that button will get you to the thumbnail viewer. The
thumbnail view will display all images, and the image you just had in the
viewer will be selected. The idea behind this is the following: you browse
to a given person, and look at the images of that
person. One of the images is from say your high school time, and now you
want to see images from that period of time. Using the <guilabel>Jump to
Context</guilabel> button, you are brought to the thumbnail view showing
all images, with the current one being in focus, and likely all your high
school pictures around it.</para>

  <para>In case you have loaded several images into the viewer, you can go
forth and back using <keycap>Page Up</keycap> and <keycap>Page
Down</keycap>. You can go to the first and last images
using <keycap>Home</keycap> and <keycap>End</keycap>. These functions
are of course also available from the context menu.</para>

  <para>If several images was loaded into the viewer, you can ask it to run
them as a slide show, which means that &kphotoalbum; loads a new image every few
second. How often it loads a new image is configure by pressing the control
key and respective plus (for go faster) or minus
(go slower). Starting and stopping the slide show is
done simply by pressing <keycombo>&Ctrl;<keycap>S</keycap></keycombo>.</para>

  <para>A very useful feature of the &kphotoalbum; viewer is it ability to go into
full screen mode. In this mode, the viewer is using the complete screen
space, simply press the return key to make it go into and out of full screen
mode.</para>

  <para>Using the viewer, you may zoom in and out of your image, simply by
dragging out a rectangle with the mouse. Pressing the minus key will zoom
out again. Pressing the plus key will zoom in at the center of the image. <xref
      linkend="fig-marking-zoom-rectangle"/> below shows how a zoom
rectangle is marked, and <xref linkend="fig-zoomed-view"/> shows the result of
the zoom.</para>

<para>Pressing the period key, lets you reset zooming, so the
image is shown un-zoomed. Pressing the equal sign will set the zoom level so
each pixel on the screen correspond to a pixel in the image.</para>

<para>Notice, for technical the only zooming operation that works when watching videos are  zoom in and out
(the plus and minus key).</para>

  <para>Choosing the rotate operations from the context menu, you may
rotate the image (Does not work for videos). You can annotate the current
image, simply by choosing <guimenuitem>Annotate</guimenuitem> in the context menu.</para>





<sect1 id="tokens">
<title>Setting Tokens from the Viewer</title>
<para>When viewing the images you may find that a given image contains a person
whose name you forgot to set on the images. At this time you may cancel
your viewing, and rush to the image configuration dialog to specify the
person. However, you may prefer to just tag the image and continue on
viewing images.</para>

<para>An alternative situation is if you want to sent a number of images
to a printer to get them developed on paper. To see which you want, you
start the viewer on the images, and tag them as good or bad while by
inspecting see each one.</para>

<para>For the above two examples the viewer offers you to set tokens on the
images when viewing them. Tokens are named from A to Z, and you set a token
simply by pressing its letter. In <xref linkend="fig-images-with-tokens"/>
you may see an image where the tokens A, B and C are set.</para>

  <figure id="fig-images-with-tokens">
    <title>An Image with Tokens</title>

          format="PNG"/>
      </imageobject>
    </mediaobject>
  </figure>

<para>Once you've set tokens on your images, they will be available for
regular browsing in the browser, as can be seen in <xref
linkend="fig-tokens-in-browser"/>. So when you've marked images that
needs to be edited, printed, or whatever, simply browse to the images, and
annotate all images at a time (as described in <xref
linkend="sect-specifying-properties-for-all-images-simultaneously"/>), use
a plugin to copy the selected images to a CD, or whatever you need to do.</para>

<para>Categories (and esp tokens) may be displayed in the thumbnail
viewer. When Showing the categories in the thumbnail viewer, you may also
add tokens to images, simply by pressing the letter for the token when the
image is selected, this can be seen in
<xref linkend="fig-tokens-in-thumbnail-viewer"/></para>

<sect1 id="category-selectors-in-viewer">
    <title>Setting Categories from the Viewer</title>
    <para>Category can be selected on viewer by starting to type the category
    name. Selection is made immediately when there is only one matching
    category left.</para>

    <para>To switch to category selection mode simply type slash (/). Possible
    options are shown after Assigning: text in curly brackets and it is
    immediately revised once more letters are typed. When a category is
    selected you can keep on typing to select the item value. Following image
    shows this in action and below it is explanation how this all works.

<para>
Follow the category setup below to better understand this explanation.
Starting by typing "/k" the input selection will shift from "Tokens" to
"Keywords" (since K is unique). After that, typing "g" will assign the "good"
keyword immediately to the image. Typing "b" will show B{ad,oring} in the info
box and typing "a" or "o" next will complete the match and assign the result to
the image. Typing "/p" will work similarly and show the partial category match
"P{eople,laces} so you can type "e" or "l" to complete "People" or "Places"
respectively.

    <title>Exact words</title>
<para>
    If you want to insert a new word or have words like boa and board you need
    to be able to type in the exact word you want to insert or select. This can
    be achieved by starting the word with double quote (") and ending with
    comma (,). If we would select boa immediately when it is typed you could
    not select board and otherwise we would be waiting for more key presses and
    you could not select boa.

<sect2>
    <title>Always start with category selection</title>
<para>
    If you type two '/'s in a row it will toggle between two different modes.
    The default mode described above and a category selection mode. In the
    latter mode we go straight back to category selection after a match.
    That way you can continually select items within different categories.
    It'll still do the fastest match possible so that typing "kbo" will still
    match "Keywords/Boring" in the example set above.
</para>

<sect2>
    <title>Assigning shortcuts</title>
<para>
    If the current input is blank (e.g. you're not in the middle of selecting
    anything) and you hit a function key F1 through F12 (or up to F35 if
    your keyboard supports), it will assign the last
    matched assignment to that key. You can apply the same assignment to
    new images just by hitting the shortcut key. To  remove use shift
    modifier and the shortcut (<keycombo>&Shift;<keycap>F#</keycap></keycombo>). This is useful for quickly assigning
    frequently repeating items in your current set of images. It
    remembers both the category and the category item. These shortcuts are
    remembered until &kphotoalbum; is closed, there is currently no
    support for replacing the assigned shortcut.
