kampos

Tiny and fast effects compositor on WebGL

Features

• Filter effects for images and videos that you can mix and compose.
• As tiny as ~4KB (minified and gzipped).
• Core engine for creating and running effects.
• Plugins for effects and transitions - available for import.
• Custom plugins? Extremely easy by using the effects/transitions descriptors DSL.

Usage

Here's a simple example for using kampos:

import { Kampos, effects } from 'kampos';

const target = document.querySelector('canvas');
const media = document.querySelector('video');

const hueSaturation = effects.hueSaturation();
hueSaturation.hue = 90;

const kampos = new Kampos({ target, effects: [hueSaturation] });

kampos.setSource(media);
kampos.play();
