worker线程里可以拿到项目内的图片吗

/ 主线程代码（entry/src/main/ets/MainPage.ets）

import worker from '@ohos.worker';


// 创建Worker实例

const workerInstance = new worker.ThreadWorker("entry/ets/workers/ImageWorker.ts");


// 方法1：传递图片的ArrayBuffer

async function sendImageAsArrayBuffer() {

  try {

    // 获取资源管理器

    const context = getContext(this) as common.UIAbilityContext;

    const resourceMgr = context.resourceManager;


    // 读取rawfile中的图片为ArrayBuffer

    const fileData = await resourceMgr.getRawFileContent('image.jpg');

    const arrayBuffer = fileData.buffer;


    // 发送到Worker线程

    workerInstance.postMessage({

      type: 'processImage',

      data: arrayBuffer

    });

  } catch (err) {

    console.error('Failed to load image:', err);

  }

}


// 方法2：传递临时文件路径（适合大文件）

async function sendImageAsFilePath() {

  const tempDir = getContext().cacheDir; // 应用缓存目录

  const sourcePath = 'entry/resources/rawfile/image.jpg';

  const destPath = `${tempDir}/image_${Date.now()}.jpg`;


  // 将图片拷贝到Worker可访问的目录

  const fs = require('@ohos.file.fs');

  await fs.copyFile(sourcePath, destPath);


  workerInstance.postMessage({

    type: 'processImage',

    filePath: destPath

  });

}
