如何使用“干预/图像”包获取修改后的图像的二进制文件？

I have a project that is written using PHP on the top of Laravel 5.7.

I am trying to use intervention/image package to interact with pictures. I want to resize an image and then get the new binaries after the picture has been resized.

So I tried something like this

$originalBinaries = $photo->getContentType(); // this is the original binaries
$image = Image::make($originalBinaries)->fit(230);
Storage::disk('local')->put('thumbnails/filename.jpeg', $image);

However, that write an images on the local storage with 0 bytes. I want to basically save the changes in Image object in memory and then get the new binary so I can write it using Laravel's Storage drive.

How can I get the updated images binaries from the Image object?
