Hi Marie, I think that u cannot export a classification as a shapefile...but u can convert ur Raster on Vector by GRASS plugin in QGIS.
1. u have to create a new Mapset on GRASS (Démarrez QGIS, cliquez sur Extensions > GRASS > Nouveau jeu de données) 2. Import your raster on GRASS ( Modules GRASS>Gestion des fichiers>Importer un raster dans GRASS>choisir la fonction "r.in.gdal.qgis.loc". 3. U have to attribute a color rules to your map "r.colors.rules" (if u had a text file with color rules, u can put from "path to rule file" ) GRASS don't recongnize other color rules, u need to do this step! 4. Convert ur raster on vector using "r.to.vect.area"! U need a large memory and time!! to do this step if not the app will crash!
