SymbolLayer

Mapbox spec: symbol

import { SymbolLayer } from '@rnmapbox/maps';

SymbolLayer

SymbolLayer is a style layer that renders icon and text labels at points or along lines on the map.

props​

id​

string

required A string that uniquely identifies the source in the style to which it is added.

existing​

boolean

The id refers to an existing layer in the style. Does not create a new layer.

sourceID​

string

The source from which to obtain the data to style. If the source has not yet been added to the current style, the behavior is undefined. Inferred from parent source only if the layer is a direct child to it.

defaults to: Mapbox.StyleSource.DefaultSourceID

sourceLayerID​

string

Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style.

aboveLayerID​

string

Inserts a layer above aboveLayerID.

belowLayerID​

string

Inserts a layer below belowLayerID

layerIndex​

number

Inserts a layer at a specified index

filter​

FilterExpression

Filter only the features in the source layer that satisfy a condition that you define

minZoomLevel​

number

The minimum zoom level at which the layer gets parsed and appears.

maxZoomLevel​

number

The maximum zoom level at which the layer gets parsed and appears.

slot​

'bottom' | 'middle' | 'top'

The slot this layer is assigned to. If specified, and a slot with that name exists, it will be placed at that position in the layer order.

v11 only

style​

SymbolLayerStyleProps

required Customizable style attributes

children​

JSX.Element | JSX.Element[]

@deprecated passed children used to create an image with id of symbol in style and also set the iconImageName property accordingly. This is now deprecated, use Image component instead.

symbolPlacement​

Name: symbolPlacement

Mapbox spec: symbol-placement

Description​

Label placement relative to its geometry.

Type​

enum

Default Value​

point

Supported Values​

point - The label is placed at the point where the geometry is located.
line - The label is placed along the line of the geometry. Can only be used on LineString and Polygon geometries.
line-center - The label is placed at the center of the line of the geometry. Can only be used on LineString and Polygon geometries. Note that a single feature in a vector tile may contain multiple line geometries.

Expression​

Parameters: zoom

symbolSpacing​

Name: symbolSpacing

Mapbox spec: symbol-spacing

Description​

Distance between two symbol anchors.

Type​

number

Default Value​

250

Units​

pixels

Minimum​

1

Expression​

Parameters: zoom

symbolAvoidEdges​

Name: symbolAvoidEdges

Mapbox spec: symbol-avoid-edges

Description​

If true, the symbols will not cross tile edges to avoid mutual collisions. Recommended in layers that don't have enough padding in the vector tile to prevent collisions, or if it is a point symbol layer placed after a line symbol layer. When using a client that supports global collision detection, like Mapbox GL JS version 0.42.0 or greater, enabling this property is not needed to prevent clipped labels at tile boundaries.

Type​

boolean

Default Value​

false

Expression​

Parameters: zoom

symbolSortKey​

Name: symbolSortKey

Mapbox spec: symbol-sort-key

Description​

Sorts features in ascending order based on this value. Features with lower sort keys are drawn and placed first. When iconAllowOverlap or textAllowOverlap is false, features with a lower sort key will have priority during placement. When iconAllowOverlap or textAllowOverlap is set to true, features with a higher sort key will overlap over features with a lower sort key.

Type​

number

Expression​

Parameters: zoom, feature

symbolZOrder​

Name: symbolZOrder

Mapbox spec: symbol-z-order

Description​

Determines whether overlapping symbols in the same layer are rendered in the order that they appear in the data source or by their yPosition relative to the viewport. To control the order and prioritization of symbols otherwise, use symbolSortKey.

Type​

enum

Default Value​

auto

Supported Values​

auto - Sorts symbols by symbol-sort-key if set. Otherwise, sorts symbols by their y-position relative to the viewport if icon-allow-overlap or text-allow-overlap is set to true or icon-ignore-placement or text-ignore-placement is false.
viewport-y - Sorts symbols by their y-position relative to the viewport if any of the following is set to true: icon-allow-overlap, text-allow-overlap, icon-ignore-placement, text-ignore-placement.
source - Sorts symbols by symbol-sort-key if set. Otherwise, no sorting is applied; symbols are rendered in the same order as the source data.

Expression​

Parameters: zoom

symbolZElevate​

Name: symbolZElevate

Mapbox spec: symbol-z-elevate

Description​

Position symbol on buildings (both fill extrusions and models) rooftops. In order to have minimal impact on performance, this is supported only when fillExtrusionHeight is not zoomDependent and remains unchanged. For fading in buildings when zooming in, fillExtrusionVerticalScale should be used and symbols would raise with building rooftops. Symbols are sorted by elevation, except in cases when viewportY sorting or symbolSortKey are applied.

Type​

boolean

Default Value​

false

Expression​

Parameters: zoom

textWritingMode​

Name: textWritingMode

Description​

The property allows control over a symbol's orientation. Note that the property values act as a hint, so that a symbol whose language doesn’t support the provided orientation will be laid out in its natural orientation. Example: English point symbol will be rendered horizontally even if array value contains single 'vertical' enum value. For symbol with point placement, the order of elements in an array define priority order for the placement of an orientation variant. For symbol with line placement, the default text writing mode is either ['horizontal', 'vertical'] or ['vertical', 'horizontal'], the order doesn't affect the placement.
