MGLRasterStyleLayer

 
@interface MGLRasterStyleLayer : MGLForegroundStyleLayer

An MGLRasterStyleLayer is a style layer that renders raster tiles on the map.

Use a raster style layer to configure the color parameters of raster tiles loaded by an MGLRasterSource object. For example, you could use a raster style layer to render Mapbox Satellite imagery, a raster tile set uploaded to Mapbox Studio, or a raster map authored in TileMill, the classic Mapbox Editor, or Mapbox Studio Classic.

You can access an existing raster style layer using the -[MGLStyle layerWithIdentifier:] method if you know its identifier; otherwise, find it using the MGLStyle.layers property. You can also create a new raster style layer and add it to the style using a method such as -[MGLStyle addLayer:].

Example

let layer = MGLRasterStyleLayer(identifier: clouds, source: source)
layer.rasterOpacity = MGLStyleValue(rawValue: 0.5)
mapView.style?.addLayer(layer)

Accessing the Paint Attributes

  • Increase or reduce the brightness of the image. The value is the maximum brightness.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 1. Set this property to nil to reset it to the default value.

    This attribute corresponds to the raster-brightness-max layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *maximumRasterBrightness;

    Swift

    var maximumRasterBrightness: MGLStyleValue

  • Increase or reduce the brightness of the image. The value is the minimum brightness.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 0. Set this property to nil to reset it to the default value.

    This attribute corresponds to the raster-brightness-min layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *minimumRasterBrightness;

    Swift

    var minimumRasterBrightness: MGLStyleValue

  • Increase or reduce the contrast of the image.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 0. Set this property to nil to reset it to the default value.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *rasterContrast;

    Swift

  • Fade duration when a new tile is added.

    This property is measured in milliseconds.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 300. Set this property to nil to reset it to the default value.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *rasterFadeDuration;

    Swift

    var rasterFadeDuration: MGLStyleValue

  • Rotates hues around the color wheel.

    This property is measured in degrees.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 0. Set this property to nil to reset it to the default value.

    This attribute corresponds to the raster-hue-rotate layout property in the Mapbox Style Specification.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *rasterHueRotation;

    Swift

    var rasterHueRotation: MGLStyleValue

  • The opacity at which the image will be drawn.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 1. Set this property to nil to reset it to the default value.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *rasterOpacity;

    Swift

    var rasterOpacity: MGLStyleValue

  • Increase or reduce the saturation of the image.

    The default value of this property is an MGLStyleValue object containing an NSNumber object containing the float 0. Set this property to nil to reset it to the default value.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic, null_resettable)
    MGLStyleValue<NSNumber *> *rasterSaturation;
