Hello,
I would like to write a qgis python plugin, which modifies cell values based on
the values of their surrounding neighbors.
But how can I iterate over a raster layer in order to read the value of each
raster cell (and its surrounding neighbors)?
Is there any method querying raster cell val
AFAIK in QGIS API there are no methods for modifying raster cells.
To learn about querying raster values look at qgsmaptoolidentify.cpp file
in QGIS source tree.
If you want not only read pixel values but modify them, look at GDAL
and NumPy.
