Class: NameLayer

Defined in: packages/core-ol/src/tools/nameLayer.ts:177

文字避让标注图层（旧库 NameLayer/vzAvoidance 移植）。

两种避让模式：

declutter（默认，已转正）：交给 ol 原生 declutter 做「重叠即隐藏」，无手写碰撞，行为稳健；
leader（@experimental）：保留旧库四方向候选框 + 引线重定位算法，密集场景有已知避让瑕疵。

Set the maximum zoom (exclusive) at which the layer is visible. Note that the zoom levels for layer visibility are based on the view zoom level, which may be different from a tile source zoom level.

Parameters

maxZoom

number

The maximum zoom of the layer.

setOpacity()

setOpacity(opacity): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/Base.d.ts:310

setProperties()

setProperties(values, silent?): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/Object.d.ts:166

Sets a collection of key-value pairs. Note that this changes any existing properties and adds new ones (it does not remove any existing properties).

Parameters

values

Partial<NoInfer<Properties>>

Values.

silent?

boolean

Update without triggering an event.

setRenderOrder()

setRenderOrder(renderOrder): void;

Parameters

renderOrder

OrderFunction | null | undefined

Render order.

Returns

void

GVectorLayer.setRenderOrder

setSource()

setSource(source): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/Layer.d.ts:369

Set the layer source.

Parameters

source

| VectorSource<Feature<Geometry, { [x: string]: any; }>> | null

The layer source.

Returns

GVectorLayer.setSource

setStyle()

setStyle(style?): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/BaseVector.d.ts:221

Set the style for features. This can be a single style object, an array of styles, or a function that takes a feature and resolution and returns an array of styles. If set to null, the layer has no style (a null style), so only features that have their own styles will be rendered in the layer. Call setStyle() without arguments to reset to the default style. See [the ol/style/Style module]module:ol/style/Style~Style for information on the default style.

If your layer has a static style, you can use [flat style]module:ol/style/flat~FlatStyle object literals instead of using the Style and symbolizer constructors (Fill, Stroke, etc.):

vectorLayer.setStyle({
  "fill-color": "yellow",
  "stroke-color": "black",
  "stroke-width": 4
})

Parameters

style?

StyleLike | FlatStyleLike | null

Layer style.

Returns

void

GVectorLayer.setStyle

Parameters

visible

boolean

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/Base.d.ts:325
