Hi Niqui --
The values in the new data-xywh-coords attribute seem significantly different than what is in the Mirador state. Is this what you would expect? For example, the x value in the screenshot is 1348 vs 14.

Also, what is the purpose of the data-parent-window-id attribute?

The mirador state is the center of the window, and Niqui's x/y coordinates are the top-left corner. That said, I'm not sure I understand the benefits of exposing this in the DOM vs using the redux state (or OSD viewer) directly. Is this a niche feature for sul-dlss/exhibits#2604 (maybe?) or is there some general utility?

[marlo-longley]

I know that getExportableState(currentState) is used to get coordinates in other applications such as MISE at Stanford.

I need the xywh coordinates to update the thumbnail view. So exhibits has the thumbnail that points the the IIIF image. In order to update that view, we need to be able to have the IIIF coordinates.

That seems like a use case pretty specific to Stanford's applications, and more appropriate as a local plugin? sul-dlss/sul-embed#2279

That works. Thanks.
