#鸿蒙通关秘籍# 如何使用鸿蒙OS通过分析图标中的像素值来调整背景色？

    const context = getContext(this);
    //获取resourceManager资源管理器
    const resourceMgr: resourceManager.ResourceManager = context.resourceManager;
    const fileData: Uint8Array = await resourceMgr.getMediaContent(this.imgData[targetIndex]);
    //获取图片的ArrayBuffer
    const buffer = fileData.buffer;
    //创建imageSource
    const imageSource: image.ImageSource = image.createImageSource(buffer);
    //创建pixelMap
    const pixelMap: image.PixelMap = await imageSource.createPixelMap();

    effectKit.createColorPicker(pixelMap, (err, colorPicker) => {
      //读取图像主色的颜色值，结果写入Color
      let color = colorPicker.getMainColorSync();
    })
