I would like to modify a raster (pixel values) in QGIS.

The plugins "value tools" can easily provided me with the value of the pixel of my raster. However I know know how to modify it.

I have found this tread saying it is possible to do it in Grass. thread I'v spent several hours on trying to understand how grass works. To complex for me...

Is it possible to access the d.rast.edit. tool from another way ? (can't find it in the sextant plugin.

Thank you for your help.
