Hi !

Georeferencing images with worldfiles is great, as it's very light and doesn't require to rewrite the raster.

Still, currently, rasters displayed this way in QGIS display a black background when rotated. One can overcome this by adding a 0 as transparent no-data value, but then every black pixel in the image becomes transparent (not only the background).

The expected behaviour is to have the image displayed with no background at all.
