TypeError when trying to create a new wxPoint

import pcbnew

def add_track(start, end, layer=pcbnew.B_Cu):
	track = pcbnew.PCB_TRACK(board)
	track.SetStart(start)
	track.SetEnd(end)
	track.SetWidth(int(0.25 * 1e6))
	track.SetLayer(layer)
	board.Add(track)

board = pcbnew.GetBoard()

for f in board.GetFootprints():
	ref =  f.GetReference()
	if ref.startswith("U"):
		num = int(ref[1:])
		dnum = (num - 1) * 8
		dnum += 2
		for i in range(1, 8):
			dref = "D" + str(dnum)
			start = board.FindFootprintByReference(dref).FindPadByNumber("1").GetCenter()
			x = start.x - 200
			x *= 1.1
			y = start.y - 200;
			y *= 1.1
			mid = pcbnew.wxPoint(x, y)
			end = board.FindFootprintByReference(ref).FindPadByNumber(str(i)).GetCenter()
			add_track(start, mid)
			dnum += 1

pcbnew.Refresh()

When I run this script I get:

Traceback (most recent call last):
  File "<input>", line 1, in <module>

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: in method 'PCB_TRACK_SetEnd', argument 2 of type 'VECTOR2I const &'

The script is supposed to draw some new tracks radiating out from a circle around point (200,200). I tried changing the call to this:

add_track(start, pcbnew.VECTOR2I(start, mid))

But that just gives a different error:

Traceback (most recent call last):

How can I fix this? Thanks.
