A sketch Render&Editor on Canvas/WebGL.

NPM version CI

Install

npm install sketch-editor

Usage

如果文档有pdf图片,需要前置引入pdfjs-dist库,也可以使用cdn文件:

<script src="https://gw.alipayobjects.com/os/lib/pdfjs-dist/3.11.174/build/pdf.min.js"></script>

如果需要颜色选择器功能,需要前置引入vanilla-picker库,也可以使用cdn文件:

<script src="https://gw.alipayobjects.com/os/lib/vanilla-picker/2.12.3/dist/vanilla-picker.min.js"></script>

拿到sketch文件的ArrayBuffer后:

import sketchEditor from 'sketch-editor';

// css自行修改引入,这里是举例
import 'sketch-editor/style.css';

// 一些建议的手动配置
sketchEditor.config.tile = true; // 开启tile优化大尺寸大文件(持续改进中)

// 一些有用的前置方法
sketchEditor.style.font.registerLocalFonts(); // 异步注册本地字体

// 真正的读取渲染逻辑
sketchEditor
  .openAndConvertSketchBuffer(arrayBuffer) // 读取sketch的buffer
  // .openAndConvertPsdBuffer(arrayBuffer) // 如果是psd用这个
  .then(json => {
    const dpi = 2;
    
    // 渲染
    const $canvasC = document.querySelector('#canvas-container');
    const { clientWidth, clientHeight } = $canvasC;
    const canvas = document.createElement('canvas');
    canvas.width = clientWidth * dpi;
    canvas.height = clientHeight * dpi;
    $canvasC.appendChild(canvas);
    const root = sketchEditor.parse(json, {
      dpi,
      canvas,
    });
    
    // 可选控制,鼠标键盘基础操作
    const listener = sketchEditor.control.initCanvasControl(root, $canvasC);
    // page列表展示
    sketchEditor.control.initPageList(root, document.querySelector('#page'), listener);
    // 图层树结构展示
    sketchEditor.control.initTree(root, document.querySelector('#tree'), listener);
    // 右侧属性面板展示
    sketchEditor.control.initPanel(root, document.querySelector('#side'), listener);
    // 缩放情况展示
    sketchEditor.control.initZoom(root, document.querySelector('#zoom'), listener);
  });

sketch-editor的诞生离不开 karas 开源项目。
