title: What EXIF lib can I use from a Qt program (on embedded linux)?
body: <p>Can anybody recommend a nice exif lib for tiff img that can be used with a Qt program? 
  I would like to both read and write exif data.</p>
  
  <p>Please note that that I need a license that is compatible with a closed source program, 
  so a lib that is using LGPL or a BSD style license would be really nice.</p>
  
  <p>My first plan was to use <a href="http://doc.qt.nokia.com/qtextended4.4/qexifimageheader.html" rel="noreferrer">QExifImageHeader</a> and <a href="http://doc.qt.nokia.com/qtextended4.4/qexifvalue.html" rel="noreferrer">QExifValue</a> in Qt Extended, 
  but then I noticed that Extended never got the LGPL licence and is on top of that it is <a href="http://qt.nokia.com/about/news/qt-software-discontinues-qt-extended" rel="noreferrer">discontinued</a>....</p>
  
  <p>The platform used is Embedded linux.</p>
  
  <p>Thanks
  Johan</p>

  <p><em>Update</em>:</p>
  
  <p>Since I'm adding a bounty for this question, 
  I'm refining the question to be about to add exif data 
  on a tiff image from a Qt program.</p>
  
  <p>A nice lib to use and a example on how to use it would be really nice.</p>
