new PIXI.Application (options)

Name Type Attributes Default Description
options object <optional>

The optional renderer parameters.

options.autoStart boolean <optional>
true

Automatically starts the rendering after the construction. Note: Setting this parameter to false does NOT stop the shared ticker even if you set options.sharedTicker to true in case that it is already started. Stop it by your own.

options.width number <optional>
800

The width of the renderers view.

options.height number <optional>
600

The height of the renderers view.

options.view HTMLCanvasElement <optional>

The canvas to use as a view, optional.

options.useContextAlpha boolean <optional>
true

Pass-through value for canvas' context alpha property. If you want to set transparency, please use backgroundAlpha. This option is for cases where the canvas needs to be opaque, possibly for performance reasons on some older devices.

options.autoDensity boolean <optional>
false

Resizes renderer view in CSS pixels to allow for resolutions other than 1.

options.antialias boolean <optional>
false

Sets antialias

options.preserveDrawingBuffer boolean <optional>

options.backgroundColor number <optional>
0x000000

The background color of the rendered area (shown if not transparent).

options.backgroundAlpha number <optional>
1

Value from 0 (fully transparent) to 1 (fully opaque).

options.clearBeforeRender boolean <optional>
true

This sets if the renderer will clear the canvas or not before the new render pass.

options.powerPreference string <optional>

Parameter passed to webgl context, set to "high-performance" for devices with dual graphics card. (WebGL only).

options.sharedTicker boolean <optional>
false

true to use PIXI.Ticker.shared, false to create new ticker. If set to false, you cannot register a handler to occur before anything that runs on the shared ticker. The system ticker will always run before both the shared ticker and the app ticker.

options.sharedLoader boolean <optional>
false

true to use PIXI.Loader.shared, false to create new Loader.

options.resizeTo Window | HTMLElement <optional>

Element to automatically resize stage to.
