If you set the stroke width to 0, there will often still be a hairline. To remove this hairline, use transparency, f.e. using:
setStrokeColor("#00000000")
hex 0-6 = color -> black
hex 6-8 = opacity -> full transparency

Please note that this function only works (as in: the stroke width changes) when setStrokeColor() is called before.
