goTo(self, layer, end_coord, start_coord=None, smooth=False)

source code

Main public method for putting the magnifier on a coordinate.

Parameters:

layer (integer) - Layer
end_coord (tuple) - Coordinate we want to reach.
start_coord (tuple) - Coordinate we are starting at, if none is given, there will be no panning.
smooth (boolean) - Use smooth panning?
