[Qgis-user] pixel counting in a raster

[Alex Mandel]

With Processing (Included in 2.2+, previously called sextante) you can
access the r.stats or r.report function directly in QGIS. If you don't
see a Processing Menu, you can enable it in the Plugin Manager.

It should be fairly straight foward to pick a loaded raster and get
results back.

Thanks,
Alex
