SVN commit 427281 by cgilles:

digiKam Aspect Ratio plugin : new photograph composition tool based on Golden Rules.

This is a very important feature for photographs. this is a great composition tool to create better images.

This new tool is inspired from famous PowerRetouche (tm) photo$hop plugin named 'Divine Proportion' (c) [ http://powerretouche.com/Divine_proportion_tutorial.htm ]. I have never seen a similar tool in Open Source world ! Now, we have one (:=)))...

New digiKam ratio crop tool screenshots can be seen at this url : http://digikam3rdparty.free.fr/RATIOCROPTOOL/

'Golden Mean' rules are very important for photograph. It's used by profesional photographers and film directors. These rules are based on Leonardo Fibonacci works (1175 - 1240 !). If you want to learn more about Golden Rules and photography composing, please take a look at these urls :

To digiKam users : I'm very happy if any photographers using digiKam 0.8.0 SVN branch can give me any feeback about this new tool.
