class FilePipeline::FileOperations::ExifRedaction
A FileOperation
that will redact (delete) unwanted Exif tags from a file's metadata.
This could be tags containing sensitive data, such as e.g. GPS location data.
Caveat: if this operation is applied to a file together with ExifRestoration
, it should be applied after the latter, to avoid redacted tags being restored.
