[Qgis-user] Counting pixels

[Sergio A Estay]

Hi everybody,

I have a apparently simple question. How can I extract the data in the 
histogram of a raster layer??

I have a geotiff layer, which contains several values in its pixels. I 
would like to know how to obtain the number of pixels with each value 
(0, 1 and 2 in my geotiff). I googled it, but I didn't find any similar.

Thanks

Sergio
