Description

I'm trying to compute hashes from my images to detect duplicates.

To do so, I strip every metadata (like keywords I may have added) then compute a CRC32.

My problem is that JpegIptcRewriter.removeIPTC() does not remove all metadata as there is always a difference of 18 bytes (containing "Photoshop 3.0").

So could it be possible to remove those 18 bytes as well in removeIPTC() so that I can compute hashes?

Thanks,

Xavier
