Basically, it can be done the same way with QGIS, but the Openlayers 
plugin background is not a raster datasource, but comes in tiles.

I have described a simple way to mask tile backgrounds here:

Second choice would be to make a screen copy with Save as Image, and 
load that as raster. The screen copy is already georeferenced.

The print composer produces raster images as well, but they are not 
georeferenced.
