MaplyShapeLinear

Objective-C

@interface MaplyShapeLinear : MaplyShape

Swift

class MaplyShapeLinear : MaplyShape

A linear feature offset from the globe.

The main difference between this object and a regular MaplyVectorObject is that you specify coordiantes in 3D. You can use this to create linear features that are offset from the globe.

  • Line width in pixels

    The linear is implemented as a set of line segments in OpenGL ES. This is their line width in pixels.

    Declaration

    Objective-C

    @property (nonatomic) float lineWidth;

    Swift

    var lineWidth: Float { get set }

  • Initialize with coordinates and coordinate array size

    This initializer will make a copy of the coordinates and use them to draw the lines. The x and y values are in geographic. The z values are offsets from the globe (or map) and are in display units. For the globe display units are based on a radius of 1.0.

    Declaration

    Objective-C

    - (nullable instancetype)initWithCoords:(MaplyCoordinate3d *_Nonnull)coords
                              numCoords:(int)numCoords;

    Swift

    init?(coords: UnsafeMutablePointer<MaplyCoordinate3d>, numCoords: Int32)

  • Return the coordinates for this linear feature.

    Declaration

    Objective-C

    - (int)getCoords:(MaplyCoordinate3d *_Nullable *_Nonnull)retCoords;

    Swift

    func getCoords(_ retCoords: UnsafeMutablePointer<UnsafeMutablePointer<MaplyCoordinate3d>?>) -> Int32

    Return Value

    Returns the number of coordinates and a pointer to the coordinate array.
