Hi, I want to update a plugin from 1.8 to QGIS 2.0 and it throws following error:
Traceback (most recent call last): File "/home/dassau/.qgis2/python/plugins/weibullanalyse/weibullanalysedialog.py", line 447, in printValue self.showValues() File "/home/dassau/.qgis2/python/plugins/weibullanalyse/weibullanalysedialog.py", line 453, in showValues self.plot() File "/home/dassau/.qgis2/python/plugins/weibullanalyse/weibullanalysedialog.py", line 514, in plot w = float(self.sampleRaster(self.InRastW.currentText(), self.xCoord, self.yCoord))/10 File "/home/dassau/.qgis2/python/plugins/weibullanalyse/weibullanalysedialog.py", line 299, in sampleRaster return self.sampleRaster20(layer, x, y) File "/home/dassau/.qgis2/python/plugins/weibullanalyse/weibullanalysedialog.py", line 284, in sampleRaster20 success, data = layer.dataProvider().identify(QgsPoint(x,y)) TypeError: QgsRasterDataProvider.identify(QgsPoint, QgsRaster.IdentifyFormat, QgsRectangle theExtent=QgsRectangle(), int theWidth=0, int theHeight=0): not enough arguments I found at http://hub.qgis.org/wiki/quantum-gis/API_changes_for_version_20 the section QgsRasterDataProvider which should fit. And the Method, where I assume the error occurs should be this # get value at mouse position QGIS <= 1.8 (working for 1.8) def sampleRaster18(self, layer, x, y): success, data = layer.identify(QgsPoint(x,y)) for band, value in data.items(): return value now what I tried but doesn't work (see error above) # get value at mouse position QGIS >= 2.0 (not working yet :() def sampleRaster20(self, layer, x, y): success, data = layer.dataProvider().identify(QgsPoint(x,y)) for band, value in data.items(): return value my problem is, that I don't understand how to implement in sampleRaster20 the new method from the API_changes_for_version_20 website which says: QMap<int, QVariant> identify( const QgsPoint & thePoint, IdentifyFormat theFormat, const QgsRectangle &theExtent = QgsRectangle(), int theWidth = 0, int theHeight = 0 ) can anybody help?
