Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

安装

npm install @iwhalecloud-lab/metamee-digital-picture2d-render

使用方法

1. 初始化

import { init } from '@iwhalecloud-lab/metamee-digital-picture2d-render';

// 初始化配置
const config = {
  id: 'avatar-container', // 挂载的DOM元素ID
  avatarImagePath: '/path/to/avatar/', // 形象图片路径
  avatarImageFileName: 'digital.gif', // 形象图片文件名
  avatarImagePlayFileName: 'digital-play.gif', // 播放中的形象图片文件名(可选)
  avatarMouthStartFileName: 'a.png', // 默认口型图片(可选,默认a.png)
  height: '400px', // 高度(可选)
  width: '300px', // 宽度(可选)
  avatarMouthStyle: 'width:25px;top:calc(50% + 15px);left:calc(50% - 23px);', // 口型图片样式(可选)
  render: 'server', // 渲染模式,可选'server'或'front',默认'server'
  hideMouth: false, // 是否隐藏嘴型,默认false
  debug: false, // 是否开启debug模式,默认false
  mouthThrottleInterval: 200, // 嘴型切换节流间隔(ms),默认200
  mouthTypeMappings: [ // 音量级别与嘴型的映射关系(可选)
    { threshold: 240, type: 'f' },
    { threshold: 180, type: 'd' },
    { threshold: 140, type: 'h' },
    { threshold: 100, type: 'e' },
    { threshold: 60, type: 'c' },
    { threshold: 20, type: 'b' },
    { threshold: -Infinity, type: 'x' }
  ],
  fftSize: 2048, // 音频分析精度,2的幂,默认2048
  options: {
    onSuccess: () => {
      console.log('初始化成功');
    },
    onError: (error) => {
      console.error('初始化失败:', error);
    }
  }
};

init(config);

2. 发送TTS请求

import { sendToTTS } from '@iwhalecloud-lab/metamee-digital-picture2d-render';

const ttsConfig = {
  url: 'https://api.example.com/tts', // TTS服务地址
  text: '你好,我是数字人', // 要转换的文本
  role: 'female', // 声音风格(可选)
  headers: {
    'Content-Type': 'application/json'
  },
  data: {}, // 额外参数(可选)
  options: {
    onSuccess: () => {
      console.log('TTS转换成功');
    },
    onError: (error) => {
      console.error('TTS转换失败:', error);
    }
  }
};

sendToTTS(ttsConfig);

3. 中断播放

import { abort } from '@iwhalecloud-lab/metamee-digital-picture2d-render';

// 中断当前播放和请求
abort();

注意事项

  1. 确保提供的图片资源路径正确。
  2. 口型图片命名需要按照a-z的格式,且需与mouthTypeMappings中的type对应。
  3. 若使用前端渲染口型(render: 'front'),需保证浏览器支持Web Audio API。
