<title>Introduction</title>

<para>
This plugin is available from within the host application. It allows to store images in JPEG format, which is usually set to a compression level that looses information (otherwise there's would be no size reduction) without losing any quality nor exif informations:
</para>

<itemizedlist>
<listitem><para>Do lossless JPEG 90/180/270 Degree Rotation.</para></listitem>
<listitem><para>Do lossless JPEG Horizontal or Vertical flip.</para></listitem>
<listitem><para>Do lossless JPEG black and white conversion.</para></listitem>
<listitem><para>Exif orientation tag based rotation or flip auto-adjustment.</para></listitem>
<listitem><para>Do lossless recompression of JPEG images.</para></listitem>
</itemizedlist>
<para>As a consequence of the lossless storage the file size will be larger (similar to the lossless PNG format) since there's no compression of the color coding information.
