  </section>

  <section xml:id="eom-features"><info><title>Image Viewer Features</title></info>
    
    <para><application>Image Viewer</application> has a variety of features to help you view your images. You can zoom in and out or view the image full screen. Regardless of your zoom level, <application>Image Viewer</application> uses a low amount of memory. You can also rotate and flip the image you are viewing.</para>

    <para>The collection view allows the viewing and editing of large image collections. In this view image operations can be applied to all selected images at once.</para>

    <para><application>Image Viewer</application> has special support for digital camera pictures and displays EXIF metadata recorded with the image. This feature requires <systemitem class="library">libexif</systemitem> to be installed on your system. All modifications made in JPEG images are lossless. That is, saving rotated and flipped JPEG images will not recompress the image. Beside this all available metadata (like EXIF) will be preserved and updated accordingly.</para>

<!-- ============= Saving Images ============================== -->
<section xml:id="eom-save-rename"><info><title>Saving Images</title></info>
	

	<para><application>Image Viewer</application> always tries to choose the save method with the least impact to the image data. For example, if an otherwise unmodified image is saved under a different name in the same format, the file is simply copied. If <systemitem class="library">libjpeg</systemitem> is available on the system all JPEG image modifications are done without loss of image information.</para>

<!--============ To Save an Image ======================= -->

If the image should be saved in another folder or the file type detection failed, expand the dialogue by clicking on <guilabel>Browse for other folders</guilabel>. This allows further folder navigation and the specification of the file type from the drop down box.</para>

	<!--============ To Save As an Image ======================= -->
	<section xml:id="eom-save-as-multiple"><info><title>Saving Multiple Images</title></info>

		<para>The folder in which the images will be saved is specified by the <guilabel>Destination folder</guilabel> drop-down box. Initially, the folder is set to the current folder. Select <guilabel>Other...</guilabel> from the drop-down list to open a standard open folder dialogue for browsing the filesystem. The resulting filename for each image is specified by <guilabel>Filename format</guilabel>. The filename schema is constructed by simple characters and special tags. The following special tags are available:</para>
		<itemizedlist>
			<listitem><para><guilabel>Filename (%f)</guilabel> - Original filename without the fileformat suffix.</para>
			</listitem>
			<listitem><para><guilabel>Counter (%n)</guilabel> - Auto-incremented number (starts at specified counter start).</para>
			</listitem>			
		</itemizedlist>	
		<para>Everything but these special tags are considered normal text.</para>
		<para>The image format is determined by the drop-down box after the schema definition. Select a specific image format or use the <guilabel>as is</guilabel> option to state that the same format as the original file should be used.</para>
	
		<para>The <guilabel>Options</guilabel> section allows to remove all space characters by underscores in the resulting filename if <guilabel>Replace spaces with underscores</guilabel> is checked. The <guilabel>Start counter at</guilabel> spin box determines at which number the counter starts if you use the %n tag for the file format specification.</para>
		<para>The <guilabel>File Name Preview</guilabel> section of the dialogue shows the resulting file name according to the above settings for an example filename from the selected images.</para>
