In Aligning Raster and vector layer using PyQGIS when they do not match?, someone gave a solution for creating a point memory layer to correctly align a raster image with a vector.
I am wondering how this can be implemented for a .PNG raster image?
I think the method is the same, just the commands would be different?
I have tried:
def addRasterImage1(self): x = self.lon0 y = self.lat0 self.layers =  fileName = 'Desktop' dir = os.path.dirname(fileName) if fileName is not None else "." #path of the saved raster image formats = ["*.%s" % "PNG"] file = myfile_list[k_zt] #raster image to load onto vector image print file if file: layer = QgsRasterLayer(file, fileName) print "layer",layer if not layer.isValid(): return # add layer to the registry QgsMapLayerRegistry.instance().addMapLayer(layer) # # set extent to the extent of layer self.canvas.setExtent(layer.extent()) self.layers.insert(0, QgsMapCanvasLayer(layer)) print "layers number:",len(self.layers) self.canvas.setLayerSet(self.layers) self.canvas.refresh() self.MyWorldLayer(ext = False)
Which produces a shifted raster png file on the vector map (the vector map is
I have then also tried changing the raster layer by resampling, similar to the code Changing Raster Layer Resampling with PyQGIS?.
