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.

Hi, again.
You'r rigth, is necesary export the raster to a grass location and mapset
bla bla bla...
I think there is a tool to do it in Qgis, is an experimental complement
"processing" [https://hub.qgis.org/projects/sextante/] maybe you should
install it.
When installed go to Processing > toolbox.
you may want to file a feature request in the bug tracker to be able to
save the raster histogram as a text file...

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

Hi Etienne
yes the Histogram works, but I taught there was also a tool that could give
me the numerical value.
Thanx

Hi Giacomo:
r.report, from GRASS complement is the tool that does directly what you are
asking for...
Good luck

Dear Qgis Community
I have a Raster layer made by pixels with 4 different values (4, 7, 17, 27).
How can i calculate the number of pixels with value 4, with value 7, with
value 17, with value 27?
Thank you very much
Giacomo
