[Qgis-user] How to probe raster values?

[Carson Farmer]

Borys,

What about using GDAL to access your raster values? Your plugin could 
get all the needed info (i.e. path, name, etc), load the data using 
GDAL, and read the data as needed using ReadRaster.

Check out: http://www.gdal.org/gdal_tutorial.html  or  
http://www.nabble.com/beginners-programming-questions-td15498345.html 
for details.

Cheers,

Carson
