[Qgis-user] pixel counting in a raster

[Marco Antonio]

Hi Giacomo, the r.stats command from GRASS complement could be useful for
you.
Open the GRASS tools and go to the console, there write:
r.stats -c raster_layer_name
the c flag prints the total count of the cells that have a certain value.

Good luck
Marco
