из хэлпа: thickness:Number (default = NaN) — An integer that indicates the thickness of the line in points; valid values are 0-255. If a number is not specified, or if the parameter is undefined, a line is not drawn. If a value of less than 0 is passed, the default is 0. The value 0 indicates hairline thickness; the maximum thickness is 255. If a value greater than 255 is passed, the default is 255.
