Hi,
thanks for your hints, I think I am on the right track now. I had a look at
the value tool plugin and tried to adapt the method accordingly:
def sampleRaster20(self, layer, x, y):
#success, data = layer.dataProvider().identify(QgsPoint(x,y))
success, data =
from the api
http://www.qgis.org/api/classQgsRasterIdentifyResult.html#a8537d25fdff215e7e9650b71a0a16783
results() returns a QMapint, QVariant (one item for each band), it
does not return a tuple, so you should actually call
ident =

It will be a QPyNullVariant so doing

Hi,
thanks for the hint. And if I need the value of the raster? If I understand
correctly, ident will always be 1, if I have a 1 band raster layer. But how
can I get the value at QgsPoint(x,y) of the raster? I don't understand that
from the value tool plugin.
In QGIS 1.8 I use :
success, data =

Have a look at the source of the value tool plugin, it calls the identify()
method and has been updated to 2.0 api.
