[Qgis-user] extraction of the value of each pixel of a raster

[skampus]

much more easier:

Sextante--> Grid Values to Point

"This module saves grid values to point (grid nodes) or polygon (grid cells)
shapes. Optionally only points can be saved, which are contained by polygons
of the specified shapes layer. In addition, it is possible to exclude all
cells that are coded NoData in the first grid of the grid list."
