When calling new OpenSeadragon.Annotations({ viewer }); there is an error

[AdamOrHd123]

Hi,
I'm trying to use the annotations.js.
I am deploying it from my main html file like this:

<script src="/static/openseadragon-annotations.js"></script>

I need to create annotation per viewer.
I'm doing it like this:
myAeeay.push(new OpenSeadragon.Annotations({viewre_}))
I get an error saying that Annotations is undefined.
What am I missing?
Really thanks for any help and guidance

Are you including the OpenSeadragon library first? Are you getting any errors loading the scripts?

Hi Ian
Thanks for reaching out
Actually I am able to create annotations by calling the api : initiaizeAnnotations()
However, there is an issue when trying to have this plug-in work on multiple instances of OSD Viewer
When I try to call this method on the second instance, I get:
Uncaught Error: The OpenSeadragon Annotations plugin is already running
This makes me understand that the plug-in can't work in parallel.
So I am using shutdownAnnotations api in order to shift between instances
But now I get a new problem, where the flow is not robust and I end up with the above error.
This makes me assume that shutdown didn't really shut/remove itself.
Did you encounter it?
This is the code I use to shift around between instances:

I actually don't know that much about this plugin. Odd that it seems to only work on one viewer at a time! What does the code look like for that? Do you literally create two viewers and then call new OpenSeadragon.Annotations({ viewer }) with each one?

Have you poked around in the code of the plugin? There might be some clues there...

Hi Ian,
Thanks for trying to help me, really
When I use: OpenSeadragon.Annotations({ viewer }), I get an error:
Uncaught SyntaxError: missing : after property id
Do you have a lead here?
I'm missing something basic.
Alternatively, I could work with Annotorious, however I don't see the controls being avaialble.
I opened an issue on the github of Annotorious.

This is the ticket I opened on Annotorious:
annotorious/annotorious-v2-openseadragon#49

When you say you use OpenSeadragon.Annotations({ viewer }), do you mean new OpenSeadragon.Annotations({ viewer })? The latter is what the docs say, and it makes a difference.

It does look like Annotorious is more actively supported than this plugin, if that makes any difference.
