I need to retrieve the epsg code of a qgis project.<br>
<br>
I know this python sintax:<br>
<br>
self.canvas.mapRenderer().destinationCrs()<br>
<br>
But it retrun me a class with inside all the elements of definition.<br>
<br>
Instead I need only the code:<br>
<br>
epsg:4326<br>
or<br>
epsg.25832<br>
and so on...<br>
<br>
Is this available in qgis API ?<br>
<br>
Thx<br>
