GLMapDrawable

Objective-C


@interface GLMapDrawable : GLMapDrawObject

Swift

class GLMapDrawable : GLMapDrawObject

GLMapDrawable is a bridge class to work with the GLMap internal representation of objects that should be rendered on the map. This can be a single image, text, or vector object. GLMapDrawable can be rendered as a separate object or injected into tile data. Check GLMapImageGroup for large groups of images or GLMapMarkerLayer to display map markers with clustering.

  • Unavailable

    GLMapDrawable is an abstract class

    Default -init is disabled.

    Declaration

    Objective-C

    - (instancetype _Nonnull)init;

Properties

  • When set to YES, the image rotates with the map. The default value is NO.

    Declaration

    Objective-C

    @property BOOL rotatesWithMap;

    Swift

    var rotatesWithMap: Bool { get set }

  • GLMapTransform mode of drawable.

    Declaration

    Objective-C

    @property GLMapTransformMode transformMode;

    Swift

    var transformMode: GLMapTransformMode { get set }

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

    Declaration

    Objective-C

    @property GLMapPoint position;

    Swift

    var position: GLMapPoint { get set }

  • Image offset from the position point, measured in image pixels. Can be used for both image and text. When the offset is (0, 0), the bottom-left corner of the image is displayed at the position. When the offset is (image.size.width / 2, 0), it is ideal for a pin. Animatable.

    Declaration

    Objective-C

    @property CGPoint offset;

    Swift

    var offset: CGPoint { get set }

  • The size of the image in pixels. Can be used for image and text.

    Declaration

    Objective-C

    @property (readonly) CGSize size;

    Swift

    var size: CGSize { get }

  • Scale of the object. The default value is 1.0. Animatable.

    Declaration

    Objective-C

    @property double scale;

    Swift

    var scale: Double { get set }

  • A float variable that defines the image angle. Animatable.

    Declaration

    Objective-C

    @property float angle;

    Swift

    var angle: Float { get set }

  • Set to true to render on terrain surface

    Declaration

    Objective-C

    @property DrawTarget drawTarget;

    Swift

    var drawTarget: DrawTarget { get set }

Methods

  • Calculates screen bbox of object

    Declaration

    Objective-C

    - (CGRect)getScreenBBoxOnMapView:(GLMapView *_Nonnull)mapView;

    Swift

    func getScreenBBox(on mapView: GLMapView) -> CGRect

    Parameters

    mapView

    The mapView where the drawable is displayed.
