RuntimeError：Frame size is not supported or is not set 错误

openmv4H7 set_windowing后报错

import sensor, image, time
from pyb import USB_VCP
usb = USB_VCP()
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.VGA)
sensor.skip_frames(time = 2000)
sensor.set_windowing((134,243,113,110))
clock = time.clock()
img = sensor.snapshot()
while(True):
	clock.tick()
	img = sensor.snapshot()

请问这是什么问题

set_windowing，里面的尺寸，必须是16的倍数。
