UX with annotations

[martinschorb]

This is related to what we implemented here:

https://github.com/mobie/clem-example-project/issues/18

• When an annotation is part of a view and thus loaded into the viewer, it appears in the sources list like the other image sources.
• there it can be toggled, its opacity can be modified and it can be deleted from that list.
• unlike other (non-exclusive) views the annotations however cannot be individually added again to create a new view.

Is it possible to generate non-exclusive views only containing the annotations and list them in a menu dropdown? Then they could be added individually to existing views.

I am not really sure what would happen in that case, but it's probably not currently possible. For some context, the sources need to be listed in the sourceAnnotationDisplay: https://github.com/mobie/mobie.github.io/blob/master/schema/view.schema.json#L272-L327

And for what you describe there wouldn't be any other displays (either segmentationDisplay or imageDisplay) that actually contain that source. This has two problems:

• it's unclear how the view with only sourceAnnotationDisplay would know about these sources then
• even worse, you can easily produce an inconsistent state where you load the view with only the sourceAnnotationDisplay but without these sources being added

This overall doesn't sound like a good idea to me because it can introduce a lot of corner cases.

so we better add the views that show a layer of sources plus their annotations as non-exclusive views, so they can be added to any other view to display these annotations?

A dirty hack would be to generate empty sources with the shape (and subsequent trafos) of the original sources and then annotate those instead of the original sources.

I suggest we discuss your use-case via zoom after Easter.
