                    -initWithDrawOrder:

Initializes an empty image that will be displayed with the given drawOrder.

Declaration

Objective-C

- (nonnull instancetype)initWithDrawOrder:(int32_t)drawOrder;

Swift

init(drawOrder: Int32)

Parameters


                                drawOrder

The draw order of the object.


                    
                    
                    -init

Initializes an image that will be injected into map tile data (for example, you can add a vector object that is drawn beneath map elements).

Declaration

Objective-C

- (nonnull instancetype)init;

Swift

init()


                    
                    
                    -setImage:completion:

Loads an image into GLMapImage. This method does not upload data to OpenGL until the image is added to a map view for rendering. The UIImage instance is retained by GLMapDrawable.

Declaration

Objective-C

- (void)setImage:(nonnull PlatformImage *)image
      completion:(dispatch_block_t _Nullable)completion;

Swift

func setImage(_ image: NSImage) async

Parameters

`image`	The new image to display on the map.
`completion`	A block called when the image is replaced.


                    
                    
                    -setImage:forMapView:completion:

Loads an image into GLMapImage and immediately uploads the OpenGL data to the specified map view. The image object itself is not retained. Call this method for every map view that will display the image.

Declaration

Objective-C

- (void)setImage:(nonnull PlatformImage *)image
      forMapView:(nonnull GLMapView *)mapView
      completion:(dispatch_block_t _Nullable)completion;

Swift

func setImage(_ image: NSImage, for mapView: GLMapView) async

Parameters

`image`	The new image to load.
`mapView`	The map view where the OpenGL resources are allocated.
`completion`	A block called when the image is replaced.
