<p>
The BlurFilter class creates a blur filter on the renderer. In contrast to the PIXI BlurFilter, you can
specify a range (defined as a PIXI.Rectangle) on which the filter should be applied.
</p>
<h2>Example with Image</h2>
<p>Let's look at an example of creating a new blur filter near the bottom:</p>
<canvas id="canvas" class="interactive"></canvas>
<p>What you should see: A sniffing hedgehog and three blurred areas (with different strengths of blur).</p>
<script class="doctest">
// Create the app
const app = new PIXIApp({
view: canvas,
width: 480,
height: 270,
transparent: false
})
.setup()
.run()
// Load a video and add it to the scene
const videoSprite = new PIXI.Sprite(PIXI.Texture.from('assets/blurfilter.mp4'))
videoSprite.width = app.size.width
videoSprite.height = app.size.height
app.scene.addChild(videoSprite)
// Create three filters and assign them to the scene
const blurFilter1 = new BlurFilter(new PIXI.Rectangle(40, 40, 120, 80))
const blurFilter2 = new BlurFilter(new PIXI.Circle(240, 140, 60), 150)
const blurFilter3 = new BlurFilter(new PIXI.Rectangle(380, 40, 100, 100), 20)
app.scene.filters = [blurFilter1, blurFilter2, blurFilter3]
</script>
