Simple Usage
import * as React from "react";
import ParticleImage, { ParticleOptions } from "react-particle-image";
const particleOptions: ParticleOptions = {
filter: ({ x, y, image }) => {
// Get pixel
const pixel = image.get(x, y);
// Make a particle for this pixel if blue > 50 (range 0-255)
return pixel.b > 50;
},
color: ({ x, y, image }) => "#61dafb"
};
export default function App() {
return (
<ParticleImage
src={"/react-logo.png"}
scale={0.75}
entropy={20}
maxParticles={4200}
particleOptions={particleOptions}
/>
);
}

Performance Tips
ParticleImage
has a target frame rate of 30fps, but with thousands of particles updating positions and repainting 30 times per second, performance can be a problem.
If animations are choppy try:
- Reducing the number of distinct particle colors (particles of the same color will be batched while painting)
- Reducing the number of particles (less than 6000 is ideal)
- Reducing the resolution of the src image.
Here's a codesandbox of a good boy to show what I mean. Note the round
function to reduce the number of colors painted on the canvas.
