I'm following the result in this answer exactly but I am receiving the following error:

ReferenceError: BinaryFile is not defined

Here's the code where that is used:

fr.onloadend = function() {
            console.log(this);
            exif = EXIF.readFromBinaryFile(new BinaryFile(this.result));
        }

The console.log shows that there is data there, I just don't understand this error I'm receiving.

Thank you for your help.

I used the following which worked very well

EXIF.getData(img, function() {
    orientation = EXIF.getTag(this, "Orientation");
});

where img is my image object.

Also EXIF.pretty(this) was helpful to see what data is in each image.

Removing BinaryFile and changing how FileReader read the file (readAsArrayBuffer) worked for me.

fileReader.onload = function (event) {

    var exif = fileReader.readFromBinaryFile(this.result);

    console.log(exif);

};

fileReader.readAsArrayBuffer(file);
