SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

PixiJS filter effects can be slow or incorrect when you don’t tune shader options, filter bounds, chaining order, and renderer-specific backbuffer needs.

Core Features & Use Cases

  • Attach effects via the filter pipeline by assigning one or multiple filters to container.filters to blur, transform colors, displace pixels, or apply alpha/noise.
  • Create custom GLSL/WGSL filters using Filter.from() (and optionally GlProgram/GpuProgram) with typed resources for uniforms and a deterministic shader pipeline.
  • Optimize performance and correctness using filterArea, resolution, padding, antialias, and blendRequired so effects render crisply without unnecessary per-frame bounds measurement.
  • Use community filters (pixi-filters) to quickly stack adjustment/glow-style effects with PixiJS v8 conventions.
  • Avoid common pitfalls like using outdated Filter constructors, over-applying filters to many children, or enabling backbuffer-dependent filters without WebGL useBackBuffer.

Quick Start

Ask the AI to help you apply a blur plus color-matrix correction to a PixiJS v8 sprite by setting sprite.filters to an array of new BlurFilter(...) and new ColorMatrixFilter() instances.

Frequently Asked Questions about pixijs-filters

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I chain multiple PixiJS filters on a single container without dropping performance?▼

To chain PixiJS filters, assign an array of filter instances to `container.filters`. Optimize rendering speed by configuring `filterArea`, `resolution`, and `padding` to prevent unnecessary per-frame bounds measurement.

How do I write a custom GLSL shader filter in PixiJS v8?▼

Create custom GLSL shaders in PixiJS v8 using `Filter.from()` with `GlProgram` or `GpuProgram`. Pass typed `resources` for uniforms to establish a deterministic shader pipeline for rendering effects.

Why does my PixiJS filter render incorrectly or fail on WebGL?▼

PixiJS filters fail on WebGL when backbuffer-dependent filters lack the `useBackBuffer` setting, or when using outdated Filter constructors. Ensure `blendRequired` behavior is correctly handled for proper rendering.

Can I use community pixi-filters with PixiJS v8?▼

Yes, community pixi-filters are supported for stacking adjustment and glow-style effects. Use them with PixiJS v8 conventions to quickly apply chained visual adjustments without writing custom shaders.

What is the best way to optimize PixiJS filter bounds for crisp rendering?▼

Optimize PixiJS filter bounds by setting `filterArea` to restrict the rendering region and tuning `padding`, `resolution`, and `antialias` options. This ensures effects render crisply without excessive computation.

When should I avoid applying filters to many children in PixiJS?▼

Avoid over-applying filters to many children in PixiJS to prevent rendering bottlenecks. Apply filters to parent containers instead, using `filterArea` to constrain the effect region and maintain performance.
