Hello everyone,
I try to load on signal, a rasterlayer to qgsmapcanvas. I try it like in
the pycookbook:
@QtCore.pyqtSlot()
def loadRasterImage(self):
print "slot works"
fileName = QFileDialog.getOpenFileName(None, "historical map",
".", "Image Files (*.png *.jpg *.bmp *.tiff)")
fileInfo = QFileInfo(fileName)
baseName = fileInfo.baseName()
rlayer = QgsRasterLayer(fileName, baseName)
if not rlayer.isValid():
print "Layer failed to load!"
QgsMapLayerRegistry.instance().addMapLayer(rlayer)
print rlayer.extent().yMinimum()
self.canvasRaster.setExtent(rlayer.extent())
self.canvasRaster.setLayerSet( [ QgsMapCanvasLayer(rlayer) ] )
self.canvasRaster is defined in the gui . I search for 8h but I dont
find a solutionen, because there are no errors.
It load the rasterlayer to the main program of qgis, but not in my
qgsmapcanvas. it is still white.
please help me.
