<title>Introduction</title>

<para>&kooka; is a &kde; application that enables easy scanning using
<acronym>SANE</acronym> libraries. Therefore,<acronym>SANE</acronym>
the package must be installed to use &kooka;. Clear and concise use
was the focus of its development.</para>

<para>Character recognition is also provided by the built-in text
recognition program gocr. Install <application>gocr</application> to
use this functionality. After character recognition is complete, the
recognized material can be opened in the text editor &kate; with just
one click, where you can edit the contents.</para>

<para>The web site <ulink

has information about supported scanners. Refer to it before
purchasing a scanner, if possible.</para>

<para>Start &kooka; from a console by simply entering
<userinput><command>kooka</command></userinput>.  Create a link on the
&kde; desktop, which uses a scanner icon, if desired.</para>

<para>The main window in &kooka; consists of three frames. At the top,
see both icon and a menu panels.  Use the mouse to enlarge or reduce
the windows as needed.</para>

<itemizedlist>

<para>The navigation window consists of two tabs, which allow you to
switch between the <guilabel>Preview</guilabel> and the integrated
file browser called the <guilabel>Gallery</guilabel>.  The working
folder is displayed in the lower part of the window along with the
folder where the scan will be saved.</para> 
</listitem>

<listitem>
<para>Make your scanner-dependent settings, which are dependent on the
scanner you have connected, in the lower left window.  Usually, these
are settings for resolution, brightness and contrast, scanning mode
(&eg;, color, gray, or binary), and for gamma values.</para>

<para>Configure your settings here first. Afterwards, initiate the
preview scan with <guimenuitem>Preview</guimenuitem>. If the
<guilabel>Preview</guilabel> tab in the upper window is selected, see
the results there.</para>

<para>Select the various formats in the preview image itself to define
the final dimensions. The <guilabel>User</guilabel> setting is
recommended for this, so you select the area to scan in the preview
display with the mouse.</para>

<para>After this is done, click <guimenu>Scan</guimenu> to scan the
selection made in the preview. After scanning, you will be asked in
which format to save the image whether to make this your standard
format (without being prompted to confirm your selection in the
future).</para>

<note><para>If you checked that you do not want to be asked about the
save format, the memory assistant will no longer appear. To change the
format some time in the future, select <menuchoice>
<guimenu>Settings</guimenu> <guimenuitem>Configure

<title>Save</title>
<subtitle>More on Saving Images</subtitle>

<para>The method for saving an image is somewhat different in &kooka;
than in many other applications. Click the
<guilabel>Gallery</guilabel> tab to open a small file browser. This is
the folder <filename
class="directory">~/.kde/share/apps/ScanImages/</filename> In the
lower portion of the window, your current subfolder in the gallery
is shown. This is where all scanned images are first saved as
files. When starting &kooka; for the first time, you will only see the
<filename class="directory">ScanImages</filename>.  Create
subfolders by <mousebutton>right</mousebutton> clicking this
folder. The selected folder, highlighted in blue, is the first save
location of the scanned images. The scans are labeled in ascending
numerical order as in <filename>kscan_0001</filename> and
<filename>kscan_0002</filename>.</para>

<para>To save an image permanently, <mousebutton>left</mousebutton>
click the name. Next, give a new name and the appropriate ending for
the image format chosen when scanning.  If you enter a different
extension, you will get a message that it does not correspond to the
scanned format. Although you can still save the image under this name,
it will retain its original format. At present,
<quote>On-the-fly</quote> conversion is not offered.</para

><para>If you do not want to use this method of managing your images
in <filename
class="directory">~/.kde/share/apps/ScanImages/</filename>, you can,
of course, save them to another location. To do this,
<mousebutton>right</mousebutton> click the
image name and select <guilabel>Save</guilabel>.  Choose any path
here. In addition, close or permanently delete images here.</para>

<para>To incorporate other images in the gallery, add them in
&konqueror; by dragging and dropping.  Open &konqueror; to the
folder containing the desired images.  Then add them to the &kooka;
gallery by dragging them and dropping them into the gallery.</para>

<chapter id="ocr">
<title>Character Recognition</title>

<para>As already mentioned, the <application>gocr</application> must
be installed. Scan a preview of your document in grayscale or
color. You can only scan in binary mode if you have a pure white sheet
of paper with black print. Next, highlight the text to be recognized
in the preview window. Then, do your final scan in binary mode with
<guibutton>Scan</guibutton>.</para>

<para>Now click the second icon from the left, 
<inlinemediaobject><imageobject>
	    <imagedata fileref="ocr-select.png" format="PNG"/>
	  </imageobject></inlinemediaobject>,   
  in the icon panel,
<guilabel>OCR on Selection...</guilabel>, or select
this item in the <guilabel>Image</guilabel> menu.  For your
first try, do not change the default settings shown in the emerging
<acronym>OCR</acronym> window. These are usually appropriate and meet
most needs.  Now click <guimenuitem>Start character
recognition</guimenuitem>. You will now see a window containing the
<acronym>OCR</acronym> results. The quality depends heavily on that of
the document itself. </para>

<screenshot> <screeninfo>The gocr Window</screeninfo> <mediaobject>
<imageobject><imagedata fileref="kooka_gocr.png"

<para>The text can now be opened by clicking the button with the
&kate; editor. After the final scan, mark a selection in the image
display to the right to load just a part of the text or image to the
<acronym>OCR</acronym>.  Next, in the icon panel, click the third
button from the right or click in the menu on
