Documentation

For ES Modules

To use, import the openseadragon-deckgl-overlay.js file and create a new instance of DeckGLOverlay.

For example:

import DeckGLOverlay from "openseadragon-deckgl-overlay.js";

const overlay = new DeckGLOverlay(this.viewer, (parent) => new Deck({
    parent,
    views: [new OrthographicView({})],
    controller: false,
    layers: [new ScatterplotLayer({id: "scatterplot", ...})]
}));

For Pure Javascript

To use, include the openseadragon-deckgl-overlay.js file after openseadragon.js on your web page.

To add deck.gl overlay capability to your OpenSeadragon Viewer, call deckGLOverlay(options) on it. The argument options is a same type of Deck constructor options.

For example:

var overlay = this.viewer.deckGLOverlay({
    layers: [new ScatterplotLayer({id: "scatterplot", ...})]
});

If you omit to set options, it will use the default options;

• views: OrthographicView is used.
• controller: false is set.

This will return a new object with the following methods:

• deck(): Gives access to Deck.
• resize(): If your viewer changes size, you'll need to resize the overlay by calling this method.

See online demo or demo.html for examples of it in use.

• typescript demo with nebula.gl
