<chapter id="introduction">
<title>Introduction</title>
<para>&skanlite; is a simple image scanning application that does nothing more than scan and save images. &skanlite; can open a save dialog for every image scanned or save the images immediately in a specified folder with auto-generated names and format. The user can also choose to show the scanned image before saving.</para>
<para>
&skanlite; can save images in all the formats supported by &Qt;. For example the following formats:
<itemizedlist>
<listitem><para>
png (8 and 16 bits per color)
</para></listitem>
<listitem><para>
jpeg, jpg, jpeg 2000
</para></listitem>
<listitem><para>
bmp
</para></listitem>
</itemizedlist>
</para>

<note><para>You can check the status of your scanner support from the SANE project website through the <ulink url="http://www.sane-project.org/sane-supported-devices.html">Supported Devices page on the SANE website</ulink>.</para></note>

<title>Scanner Selection</title>
<para>A default scanner can be specified on the command line of &skanlite; using <userinput>skanlite -d [device name]</userinput> in a terminal. If the selected scanner cannot be opened or if no default scanner is provided, a scanner selection dialog is opened.

<para>
In case no devices were found, maybe because the scanner is not plugged in or 
switched off, correct that. Then the <guibutton>Reload device list</guibutton> 
can be used to reload the list of scanners.</para> 
<note><para>Not all drivers/backends support this feature. In that case quit &skanlite;, 
connect your scanner and restart the application.</para>

<title>&skanlite; Main Window</title>

	  </textobject>
	</mediaobject>
</screenshot>

<para>
In the main window, the user has two sets of scan options: <guilabel>Basic Options</guilabel> and <guilabel>Scanner Specific Options</guilabel>. The <guilabel>Basic Options</guilabel> tab contains the most common parameters that the SANE scanner backends provide, while the <guilabel>Scanner Specific Options</guilabel> tab contains all the options of the backend. The options listed here depend on SANE support for your driver: libksane (which &skanlite; uses) should be able to display most of the types of parameters that SANE provides (analog gamma tables are not supported at this time).
</para>

	</mediaobject>
</screenshot>

<para>
The scanner specific options contains more detailed options of the backends. &skanlite; (libksane) does not have any special handling for these options.
</para>

<para>If you are satisfied with your settings, you can use the little arrow on the top of the options splitter. 
When clicked it collapses or expands the options. The collapser can overlap the preview area, but fades
away when the mouse cursor moves out of the collapser.</para>  

<sect1 id="scanning">
<title>Scanning</title>
<para>
To scan an image, the user can start with a preview scan and then select the part of the scan area to do the final scan on. The preview scan is started by pressing the preview button.

<title>Scanning Multiple Selections</title>
<para>
Sometimes you need only certain parts of an image.
Instead of scanning the whole picture and then using a graphics
application (&eg; &kolourpaint;) to save the different image parts into separate
files, use &skanlite;'s  multiple selection feature.

<para>Scan a preview and then use the &LMB; to select the first part of the image in the preview.
Hover the selected area with mouse cursor and click on the green <guiicon>+</guiicon> icon
to select the area.  Selected areas are indicated by a red border.
Now select the next parts of the image in the same way.</para>
<para>To remove a single selection hover the area with the mouse cursor and click on the red
<guiicon>-</guiicon> icon. With <guilabel>Clear Selections</guilabel> from the context menu launched with the
&RMB; all selections in a preview can be removed.
</para>
<para>If you placed two separate images or photos on you scanner and started a preview 
&skanlite; automatically preselect the different areas. This behaviour can be switched off in the settings dialog.
</para>
<para>If you are satisfied with your choice starting the final batch scan of all selections. The images are saved
using the batch renaming feature described in the settings dialog.

<para> This setting allows you to choose how &skanlite; will save the images. If you choose <guilabel>Open the save dialog for every image</guilabel> the save dialog will be opened for every scanned image. If you prefer &skanlite; to auto-save (by auto-generating a name and saving the image in a predefined folder) you can choose <guilabel>Open the save dialog for the first image only</guilabel>. This option will open the following "Save Location" dialog for the first scanned image.</para>

<varlistentry>
<term><guilabel>Name Format:</guilabel></term>
<listitem><para> This parameter defines the image prefix for the auto-saved images and is also the suggested name for the image in the save dialog. The auto-saved image will have a numeric suffix (the ### will be replaced by numbers) that is increased every time an image is saved.

<term><guilabel>Set preview resolution (DPI)</guilabel></term>
<listitem><para>&skanlite; is using heuristics to try to get a sane resolution,

resolution can be manually set with this option.

</varlistentry>
<varlistentry>
<term><guilabel>Disable automatic selections</guilabel></term>
<listitem><para>By default automatic selections are enabled; and after a preview, 
libksane does try to automatically select the images in the preview and should
batch scan the selected areas. &eg; if you place two photos 
on the scanner and do a preview, &skanlite; will automatically add 
selections of the photos.</para>
<para>If on the other hand you are usually scanning documents it might be that the 
automatic selection will select a lot of different parts in the documents and 
you have to manually remove the selections. To avoid that tick the checkbox and
disable automatic selection.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term><guilabel>Revert scanner options to default values</guilabel></term>
<listitem><para>
The last used settings are reloaded on startup. If you have screwed up the options 
(for example if you have changed the color correction settings, available
in some backends, without knowing what they mean), the image can start to look very odd. 
For that scenario this option provides a way to revert the setting to the default values, 
which are a combination of backend and libksane defaults.
