XMP Category values

[Matous Bocek]

Hey, thanks for writing this tool!

I found issue with processing XMP Category values. It returns mixed values for photo with 2 recognized faces and some values for Region Extensions are missing:

Results from NExifTool:
XMP Toolkit: XMP Core 5.4.0
Region Area Y: 0.4605000.471000
Region Area W: 0.0440000.033000
Region Area X: 0.4450000.325500
Region Area H: 0.0590000.044000
Region Area Unit: normalizednormalized
Region Type: FaceFace
Region Applied To Dimensions H: 3024
Region Applied To Dimensions W: 4032
Region Applied To Dimensions Unit: pixel

There is attached image, which caused issues:

Thanks for the detailed report! I will look at this when I find some free time.

After some testing, I believe the tags were being parsed and made available, but you would have had to find these by looking by the Tag ID, such as "apple-fi:RegionsRegionListExtensionsAngleInfoYaw", as the name field is not currently set in this condition.

I have made a small update to also populate the name when we encounter a tag that is not known ahead of time. The name will either match the ID, or the value after the last ':' in the tag id. In the above example, you should now see the tag when searching for a name with RegionsRegionListExtensionsAngleInfoYaw.

This update is available in v0.8.2.

Also, I hope you don't mind, but I have included the example picture above in the test project. If you do mind, please let me know and I will remove the image and test case.

Thanks,
-Mike

Sorry for the long delay, I have just released a pre-release version (0.9.0-beta) which should address most scenarios for getting list data out. You can see an example in the overhaul branch; have a look at ParseTests.cs:GetRegionExtensionsTags().

Note that there were a number of breaking changes introduced, but hopefully they are pretty straightforward to work through.

Thanks!

This should be addressed in v0.9.0.
