I am trying to extract EXIF data from a image(jpeg) which has been dragged into the browser or has been selected via a html file input element.
I managed to preview the image within the browser using
FileReader and FileReader.readAsDataURL
as described here
and I found a EXIF library
tags which load their content over a URL.
I also found this question
on stackoverflow where the accepted answer states that it is just not possible.
But I am pretty sure that it can be realized because 500px.com
extracts the EXIF data immediately after a file is added for upload and before the upload has been finished.
Some ideas how it should be possible to extract the EXIF data from the base64 encoded image I get from the FileReader?
Thanks a lot for your help!
