Can we get some examples of how WebMapManager interfaces with the MapManagerCoreAPI

[cudmore]

Hi @Suhayb-A, Can you push a recent dev branch of WebMapManager? It is ok if some things are broken.

Can you post (here) some code examples of how you query the MapManagerCore API? And @jtle00, I know you worked on this within PyMapManager so any feedback is super welcome.

For example, when the viewer sets a new image slice, what is your code to request the point and line data to display?

Are you calling something like this in AnnotationsLayers

getAnnotations(self, options: AnnotationsOptions) -> list[Layer]:

With that as an example, can you give us some samples of the key/value pairs in options and the type of data it returns. Not sure getAnnotations() is a good example, please give better or more recent examples as needed.

Even just a code block of what options and list[Layers looks like would be great.

With a loaded map, I tried something like the following and get loads of key errors depending on my selection of options.

from mapmanagercore.annotations.layers import AnnotationsOptions, ImageViewSelection, AnnotationsSelection

options = AnnotationsOptions(
    selection=ImageViewSelection(z=(0,50)),
    annotationSelections=AnnotationsSelection(spineID=10, segmentID=0, segmentIDEditing=0),
    showSpines=True,
    showLineSegments=True,
    showAnchors=True,
    showLabels=False,
    showLineSegmentsRadius=False
)

layerList = map.getAnnotations(options)

With showSpines=False I get an empty list of layers. With showSPines=True I get the following error.

Please ignore if this is fixed in a more recent version.
