[Qgis-developer] Bringing the raster processing algorithms of the Orfeo Toolbox Monteverdi in QGIS

[Pirmin Kalberer]

Salut Manuel
You could also have a look at PluginLayer class introduced in 1.5.
A simple usage example is here: 
http://github.com/sourcepole/qgis-watermark-plugin
Looking forward to discuss that in Barcelona!
