AI-generated Key Takeaways

• GMSStrokeStyle defines the visual appearance of lines or strokes on a map, such as polylines.

• It supports solid colors, gradients, and repeating image patterns (stamps) for styling.

• Strokes can be made transparent while still displaying a stamp pattern.

• Developers can create GMSStrokeStyle instances using convenience methods for solid colors, gradients, or stamps.

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.

  Declaration

  Swift

  var stampStyle: GMSStampStyle? { get set }

  Objective-C

  @property (nonatomic, strong, nullable) GMSStampStyle *stampStyle;

• +solidColor:

  Creates a solid color stroke style.

  Declaration

  Swift

  class func solidColor(_ color: UIColor) -> Self

  Objective-C

  + (nonnull instancetype)solidColor:(nonnull UIColor *)color;

• +gradientFromColor:toColor:

  Creates a gradient stroke style interpolating from fromColor to toColor.

  Declaration

  Swift

  class func gradient(from fromColor: UIColor, to toColor: UIColor) -> Self

  Objective-C

  + (nonnull instancetype)gradientFromColor:(nonnull UIColor *)fromColor
                                    toColor:(nonnull UIColor *)toColor;

• +transparentStrokeWithStampStyle:

  Creates a transparent stroke style and sets the stampStyle.

  Declaration

  Swift

  class func transparentStroke(withStamp stampStyle: GMSStampStyle) -> Self

  Objective-C

  + (nonnull instancetype)transparentStrokeWithStampStyle:
      (nonnull GMSStampStyle *)stampStyle;
