<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>
