I have a number of family photographs that I'd like to annotate. A lot of these photographs already have people identified in them courtesy of Picasa. I'd like to know:
- Is there a standard way of defining and embedding a region of interest in a photograph? - Are there any image viewers that currently use that standard? - Is there a way of embedding Picasa's region of interest definitions into the photograph? I understand that Picasa saves this metadata in a separate file rather than in the original photograph. Cheers, Mark
