MaplyVectorStyleSettings

Objective-C

@interface MaplyVectorStyleSettings : NSObject

Swift

class MaplyVectorStyleSettings : NSObject

Settings that control how vector tiles look in relation to their styles.

These are set based on the sort of device we’re on, particularly retina vs. non-retina. They can be manipulated directly as well for your needs.

  • Initialize with the (presumably) retina scale

    Declaration

    Objective-C

    - (instancetype _Nonnull)initWithScale:(CGFloat)scale;

    Swift

    init(scale: CGFloat)

  • Line widths will be scaled by this amount before display.

    Declaration

    Objective-C

    @property (nonatomic) float lineScale;

    Swift

    var lineScale: Float { get set }

  • Text sizes will be scaled by this amount before display.

    Declaration

    Objective-C

    @property (nonatomic) float textScale;

    Swift

    var textScale: Float { get set }

  • Markers will be scaled by this amount before display.

    Declaration

    Objective-C

    @property (nonatomic) float markerScale;

    Swift

    var markerScale: Float { get set }

  • Importance for markers in the layout engine

    Declaration

    Objective-C

    @property (nonatomic) float markerImportance;

    Swift

    var markerImportance: Float { get set }

  • Default marker size when none is specified

    Declaration

    Objective-C

    @property (nonatomic) float markerSize;

    Swift

    var markerSize: Float { get set }

  • Importance for labels in the layout engine

    Declaration

    Objective-C

    @property (nonatomic) float labelImportance;

    Swift

    var labelImportance: Float { get set }

  • If set we’ll use the zoom levels defined in the style

    Declaration

    Objective-C

    @property (nonatomic) _Bool useZoomLevels;

    Swift

    var useZoomLevels: Bool { get set }

  • For symbols we’ll try to pull a UUID out of this field to stick in the marker and label uniqueID

    Declaration

    Objective-C

    @property (nonatomic, nullable) NSString *uuidField;

    Swift

    var uuidField: String? { get set }

  • Draw priority calculated as offset from here

    Declaration

    Objective-C

    @property (nonatomic) int baseDrawPriority;

    Swift

    var baseDrawPriority: Int32 { get set }

  • Offset between levels

    Declaration

    Objective-C

    @property (nonatomic) int drawPriorityPerLevel;

    Swift

    var drawPriorityPerLevel: Int32 { get set }

  • The overall map scale calculations will be scaled by this amount.

    We use the map scale calculations to figure out what is dispalyed and when. Not what to load in, mind you, that’s a separate, but related calculation. This controls the scaling of those calculations. Scale it down to load things in later, up to load them in sooner.

    Declaration

    Objective-C

    @property (nonatomic) float mapScaleScale;

    Swift

    var mapScaleScale: Float { get set }

  • Dashed lines will be scaled by this amount before display.

    Declaration

    Objective-C

    @property (nonatomic) float dashPatternScale;

    Swift

    var dashPatternScale: Float { get set }

  • Use widened vectors (which do anti-aliasing and such)

    Declaration

    Objective-C

    @property (nonatomic) _Bool useWideVectors;

    Swift

    var useWideVectors: Bool { get set }

  • Where we’re using old vectors (e.g. not wide) scale them by this amount

    Declaration

    Objective-C

    @property (nonatomic) float oldVecWidthScale;

    Swift

    var oldVecWidthScale: Float { get set }

  • If we’re using widened vectors, only activate them for strokes wider than this. Defaults to zero.

    Declaration

    Objective-C

    @property (nonatomic) float wideVecCuttoff;

    Swift

    var wideVecCuttoff: Float { get set }

  • If set, this is the shader we’ll use on the areal features.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable arealShaderName;

    Swift

    var arealShaderName: String? { get set }

  • If set, we’ll make all the features selectable. If not, we won’t.

    Declaration

    Objective-C

    @property (nonatomic) _Bool selectable;

    Swift

    var selectable: Bool { get set }

  • If set, icons will be loaded from this directory

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable iconDirectory;

    Swift

    var iconDirectory: String? { get set }

  • The default font family for all text

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable fontName;

    Swift

    var fontName: String? { get set }
