Can't get CROP values

[HolyOne]

Hello, I use MyFamilyTree for my family tree and I upload images for individuals and select faces in the photos.
However I am unable to get information about cropping boundries with this library.
This is an example content of my ged file

I've not seen the _Multimedia_uses custom gedcom tag before. It definitely won't handle this, but if you have a data file so I can see how it works I can look at for an update. But it may not be soon.

If you are able to share a gedcom, let me know and I'll give you my email address.

Here is a sample tree I generated with MyFamilyTree application with pictures. It may have additional properties. but it should be fully compatible with gedcom7

Can you give me advice how to implement this feature, I could not figure out where the CROP is feeded to the reader class.
