pixijs-filters
This skill teaches you how to leverage PixiJS v8's powerful filter system to enhance your 2D graphics with visual effects. You'll learn to apply filters to display objects, chain multiple effects together, and optimize performance when working with complex rendering scenarios. Master both built-in filters and custom implementations to bring professional polish to your WebGL and Canvas-based applications.
pixijs-filters lets you apply blur and other effects to display objects using the filters array. Create a filter instance (like BlurFilter), then assign it to your sprite or container's filters property. For example: `sprite.filters = [new PIXI.BlurFilter()]`. You can chain multiple filters together by adding them to the array, and pixijs-filters handles rendering them in sequence for professional visual effects.

How do I apply a blur filter in pixi.js?
pixijs-filters lets you apply blur and other effects to display objects using the filters array. Create a filter instance (like BlurFilter), then assign it to your sprite or container's filters property. For example: `sprite.filters = [new PIXI.BlurFilter()]`. You can chain multiple filters together by adding them to the array, and pixijs-filters handles rendering them in sequence for professional visual effects.
What is Filter.from and how do I use GLSL with pixijs-filters?
pixijs-filters provides Filter.from() to create custom filters using GLSL or WGSL shaders. This method lets you define vertex and fragment shaders for advanced effects beyond built-in filters. You specify your shader code and uniform values, then pixijs-filters compiles and applies them to your display objects. This is ideal for creating unique visual effects tailored to your application's needs.
How can I optimize filter performance with resolution and filterArea?
pixijs-filters performance depends on resolution and filterArea settings. Lower resolution reduces GPU load but may blur quality; filterArea defines the region affected by the filter. Adjust these properties based on your target performance. For complex scenes, use smaller filterArea values or lower resolution on non-critical filters. pixijs-filters also supports padding and antialias options to balance visual quality with rendering speed.
Can I chain multiple effects together in pixijs-filters?
Yes, pixijs-filters supports chaining by adding multiple filter instances to the filters array. For example: `sprite.filters = [new PIXI.BlurFilter(), new PIXI.ColorMatrixFilter()]`. pixijs-filters applies them in order, letting you combine blur, color adjustments, displacement maps, and custom shaders. Configure each filter's options like blend mode and padding independently for complete creative control.
What does the pixi-filters package offer beyond built-in filters?
The community pixi-filters package extends pixijs-filters with advanced effects like glow, adjustment, and specialized visual enhancements. It provides pre-built, optimized implementations of complex effects that would be time-consuming to create from scratch. Use it alongside pixijs-filters' core system to access professional-grade effects with minimal configuration.
How do I configure filter options like padding, antialias, and blend mode?
pixijs-filters lets you customize filter behavior through properties like padding (adds buffer around filterArea), antialias (smooths edges), and blendRequired (determines WebGL back buffer usage). Set these on your filter instance before applying it: `filter.padding = 10; filter.antialias = true`. These options control rendering quality, performance, and how filters interact with underlying content.

rendered from the published skill — quoted content, verbatim
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
```ts 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
