如何让 ImageResizer 加载源图像？

Question

我在我的 React Native 应用程序中使用react-native-image-resizer 。

我尝试将assetPath、pathURI 和图像（见下文）提供给ImageResizer，并且总是得到相同的消息：

err on ImageResizer Unable to load source image from path

我已经验证 uri64 确实对文件进行了编码，所以我知道文件路径和 URI 是正确的。

 let maxWidth = 24;
  let maxHeight = 24;
  let compressFormat = "PNG";
  let quality = 100; // only used for jpeg
  let rotation = 0;
  let outputPath = ".";
  let options = {};
  let keepMeta = false;

  const assetPath = "../../../../../assets/Knob-54px.png" 
  const pathURI = "file://" + assetPath

  const uri64 =  Base64.encodeURI(pathURI ); 
  const image = 'data:image/jpeg;base64,' + uri64; 

  console.log("uri64 ", uri64);
  console.log("image ", image);
   

  ImageResizer.createResizedImage(pathURI or assetPath or image, maxWidth, maxHeight, 
    'PNG', quality, rotation, outputPath)
    //, keepMeta = false,
    //options = {mode: 'contain'})
  .then(response => {
    console.log("response.uri ", response.uri)
    console.log("response.path ", response.path)
    console.log("response.name ", response.name)
    console.log("response.size ", response.size)

    // response.uri is the URI of the new image that can now be displayed, uploaded...
    // response.path is the path of the new image
    // response.name is the name of the new image with the extension
    // response.size is the size of the new image
  })
  .catch(err => {
    console.log("err on ImageResizer", err)
    // Oops, something went wrong. Check that the filename is correct and
    // inspect err to get more details.
  });

这是 ImageResizer 的 GitHub 上的源代码：
