setMinZoom()

setMinZoom(minZoom): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/Base.d.ts:303

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>>

silent?

boolean

Update without triggering an event.

setRadius()

setRadius(radius): void;

Defined in: node_modules/.pnpm/ol@10.9.0/node_modules/ol/layer/Heatmap.d.ts:190

Set the size of the radius in pixels.

Parameters

setRenderOrder()

setRenderOrder(renderOrder): void;

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

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
