CanvasSourceOptions

src/source/canvas_source.js

Options to add a canvas source type to the map.

Properties

type(string): Source type. Must be "canvas" .
canvas((string | HTMLCanvasElement)): Canvas source from which to read pixels. Can be a string representing the ID of the canvas element, or the HTMLCanvasElement itself.
coordinates(Array<Array<number>>): Four geographical coordinates denoting where to place the corners of the canvas, specified in [longitude, latitude] pairs.
animate(boolean?): Whether the canvas source is animated. If the canvas is static (i.e. pixels do not need to be re-read on every frame), animate should be set to false to improve performance.
