  • Initializes empty image that will be displayed with given drawOrder

    Declaration

    Objective-C

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

    Parameters

    drawOrder

    drawOrder of object

  • Initializes image that will be injected into map tile data (for example you can set vector object that can be displayed under map elements)

    Declaration

    Objective-C

    - (instancetype _Nonnull)init;

Properties

  • When set to YES image rotates with map. Default value is ‘NO’

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite) BOOL rotatesWithMap;

  • GLMapTransform mode of drawable

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite)
    GLMapTransformMode transformMode;

  • A position that sets image position in map internal coordinates For vector object adds translation Animatable.

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite) GLMapPoint position;

  • Image offset from position point. Can be used for image and text When offset is (0,0), bottom left corner of image is displayed at position Animatable.

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite) CGPoint offset;

  • A size of image in pixels Can be used for image and text

    Declaration

    Objective-C

    @property (atomic, readonly) CGSize size;

  • Scale of object. (by default is 1.0) Animatable.

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite) double scale;

  • A float variable that defines image angle Animatable.

    Declaration

    Objective-C

    @property (atomic, assign, unsafe_unretained, readwrite) float angle;

Methods

  • Loads image into GLMapDrawable This variant will not load anything into OpenGL util GLMapDrawable will be added to some mapView that will try to render it. UIImage will be retained by GLMapDrawable.

    Declaration

    Objective-C

    - (void)setImage:(UIImage *_Nonnull)image
      completion:(dispatch_block_t _Nullable)completion;

    Parameters

    image

    New image to display on map
    completion

    A block called when image is replaced.

  • Loads image into GLMapDrawable This variant of function loads OpenGL data into given mapView and does not retain image itself You must call this function for every mapView where you will display the image

    Declaration

    Objective-C

    - (void)setImage:(UIImage *_Nonnull)image
      forMapView:(GLMapView *_Nonnull)mapView
      completion:(dispatch_block_t _Nullable)completion;

    Parameters

    image

    New image to laod
    mapView

    where to load openGL resources
    completion

    A block called when image is replaced.

  • Sets text to draw

    See

    GLMapVectorStyle

    Declaration

    Objective-C

    - (void)setText:(NSString *_Nonnull)text
      withStyle:(GLMapVectorStyle *_Nonnull)style
     completion:(dispatch_block_t _Nullable)completion;

    Parameters

    text

    New text
    style

    A style object used for text
    completion

    A block called when text is replaced.

  • Sets vector object to draw

    See

    GLMapVectorStyle

    Declaration

    Objective-C

    - (void)setVectorObject:(GLMapVectorObject *_Nonnull)object
              withStyle:(GLMapVectorCascadeStyle *_Nonnull)style
             completion:(dispatch_block_t _Nullable)completion;

    Parameters

    object

    object to draw
    style

    A style of object
    completion

    A block called when object ready to draw

  • Sets vector objects to draw

    See

    GLMapVectorStyle

    Declaration

    Objective-C

    - (void)setVectorObjects:(GLMapVectorObjectArray *_Nonnull)objects
               withStyle:(GLMapVectorCascadeStyle *_Nonnull)style
              completion:(dispatch_block_t _Nullable)completion;

    Parameters

    objects

    objects to draw
    style

    A style of object
    completion

    A block called when object ready to draw

  • Tests if point is inside of image

    Declaration

    Objective-C

    - (BOOL)hitTest:(CGPoint)point
           onMap:(GLMapView *_Nonnull)mapView
    withPaddings:(UIEdgeInsets)paddings;

    Parameters

    mapView where images is displayed
    point

    point to check
    paddings

    paddings of image
