 Replying to [comment:21 rblazek]:
 > Isn't it bug in the plugin? Should not they check 'if cstr'? Where can I
 find the plugin?! I cannot find it on internet. The installer in QGIS is
 currently disabled. I have to see which values it reads and if they can be
 passed from the provider with current raster providers implementation.


 Hi,
 the "value tool" plugin is in the contributed repository, available among
 all the others. As far as I can remember it always worked fine with GRASS
 rasters. In fact it is one of that tools we use more when we reclassify
 rasters (and  show how to), use r.mapcalc, etc.




 > Does it work with WMS layer?



 as far as I know, no.

 by valuetool?

 readable info.


 You may want to ask this in the dev mailing list.
