import { image } from '@kit.ImageKit' 
try { 
  // 媒体文件字节数组 
  getContext().resourceManager.getMediaContent($r('app.media.icon').id, (error, value:ArrayBuffer) => { 
    let opts: image.InitializationOptions = { 
      editable: true, 
      pixelFormat: 3, 
      size: { height: 4, width: 6 } 
    } 
 
    // 创建PixelMap 
    image.createPixelMap(value, opts).then((pixelmap) => { 
      // ... 
    }) 
  }); 
} catch (error) { 
  console.error(`callback getMediaContent failed, error code: ${error.code}, message: ${error.message}.`) 
}
