How to openseadragon annotorious - openseadragon, fabricjs combination used?

[Whao510]

Where openseadragon uses annotorious-openseadragon, how can I use it with fabricjs?I desperately need help。

Currently openseadragon is used with annotorious, but I would like to add fabricjs to extend the measurement and screenshot capabilities

I'm not sure I understand exactly what you mean. Do you want to use FabricJS instead of Annotorious? Did you look into this: https://github.com/altert/OpenseadragonFabricjsOverlay

Either way, I'm afraid I can only answer questions about Annotorious here. For anything else around OpenSeadragon, did you check their support channels?

P.S. for screenshots, also see html2canvas: https://html2canvas.hertzen.com/ (This is completely separate from OpenSeadragon, and would work with any website.)

For measurements, did you see this plugin? https://github.com/verrochi92/OSDMeasure
