Attach visual effects by assigning one filter (or an array for chaining) to container.filters. Built-in filters cover blur, color matrix, displacement, alpha, and noise; custom filters wrap a GLSL/WGSL fragment shader via Filter.from(...).
Quick Start
const sprite = new Sprite(await Assets.load("hero.png"));
app.stage.addChild(sprite);
const blur = new BlurFilter({ strength: 4, quality: 4 });
const colorMatrix = new ColorMatrixFilter();
colorMatrix.brightness(1.2, false);
sprite.filters = [blur, colorMatrix];
const container = new Container();
container.filters = [new BlurFilter({ strength: 2 })];
container.filterArea = new Rectangle(0, 0, 800, 600);
app.stage.addChild(container);
