TiledImageBackgroundComponentProps

Props for the tiled image background component

Properties

height

height: number

Required. Indicates the height of the full image.


maxZoom

maxZoom: number

Required. Indicates the maximum zoom level. Zoom starts at 0 - fully zoomed out - and increases in integer values from there. Each successive zoom level is twice the zoom of the previous level, meaning two times as many tiles in each direction.


panDebounceTimeout?

optional panDebounceTimeout: number

How long to wait after a pan before reloading tiles.


tileSize

tileSize: Size

For tiled backgrounds, provides the width and height of tiles. Every tile is assumed to have these dimensions, even if the tile has whitespace in it. Required.


tiling?

optional tiling: TilingStrategy

Default is TilingStrategies.logarithmic. See notes for TilingStrategies enum.


url?

optional url: string

URL for the background. You can supply this, or you can supply a urlGenerator function instead. If you supply url and no urlGenerator, the url you supply is treated as a template for the url for any given tile, and is expected to contain {z}, {x} and {y} placeholders. The form of the URL can be anything you like as long as it has the placeholders for z, x and y. For instance:

http://foo.com/{z}/{x}/{y} https://bar.com?zoom={z}&x={x}&y={y}

etc


urlGenerator()?

optional urlGenerator: (z, x, y) => string

For tiled backgrounds, an optional function you can supply to generate the URL for a given tile. See url for an explanation of the default syntax for urls when using a tiled background.
