GMSStrokeStyle

@interface GMSStrokeStyle : NSObject

Describes the drawing style for one-dimensional entities such as polylines.

stampStyle
A repeated image over the stroke to allow a user to set a 2D texture on top of a stroke. If the image has transparent or semi-transparent portions, the underlying stroke color will show through in those places. Solid portions of the stamp will completely cover the base stroke.
