Description hardy.public 2017-12-23 11:05:36 UTC

If an image with multiple face tags is cropped and saved as a new image, all face regions are retained in the metadata giving meaningless face tags in the new image.

Expected Behaviour
==================

Minimum:
All regions should be deleted from the metadata in the new image.

Ideal:
If technically possible, whole face regions within the boundaries of the new cropped image should be rescaled and retained. All other regions should be deleted from the metadata.

Yes and no. The cropped image now doesn't contain any face regions which is good as an interim solution. Ideally though, I think a cropped image should have its face regions recalculated whre possible.
