method 1:

You just need pass gif url(such as https://xxx.gif) and filter url(such as https://yyy.png) to mixFilterToGIF function ( It is important to note that the url must allow cross-origin! ).

你只需要向 mixFilterToGIF 函数分别传 gif url 和 滤镜 url 就可以了（务必注意 url 必须允许跨域！）

import { mixFilterToGIF } from "colorful_gif";
// if in commonjs, use:
// const { mixFilterToGIF } = require("colorful_gif")
// if import from <script src="**/colorful_gif.min.js" />, use directly:
// window.ColorfulGif.mixFilterToGIF

mixFilterToGIF("xxx.gif", "yyy.png").then((newGIFDataURL) => {
  // this will output new gif dataURL
  console.log(newGIFDataURL);

  // you can use this url to do anything……
});

method 2:

Also you can pass HTMLImageElements to mixFilterToGIF function. Look at example below:

或者你可以给 mixFilterToGIF 函数传入 image 元素，请看下面的例子：

Assume you have a html file like this:

假设你有一个像下面这样的 HTML：

<img id="gif" src="https://xxx.gif" />

<img id="filter" src="https://xxx.png" />

<img id="result" src="" />

You can do this in JavaScript file:

你可以在 JavaScript 里面这样做：

import { mixFilterToGIF } from "colorful_gif";

mixFilterToGIF(
  document.querySelector("#gif"),
  document.querySelector("#filter")
).then((newGIFDataURL) => {
  // this will output new gif dataURL 这里将打印出一个新的gif dataURL
  console.log(newGIFDataURL);

  // give this url to an image element
  const resultImage = document.querySelector("#result");
  resultImage.src = newGIFDataURL;
});

In the end, the img element what's id is result will show a new gif with filter.

最终，id 为 result 的 img 元素会展示新的带有滤镜的 gif。
