Is it possible to clear all the annotations in realtime?

[Songhao-LI]

for now, I found clearAnnotations() is deleting all the annotations using a loop? So, when the dataset is huge, it may take a long time to remove all the annotations, is there any more efficient ways to solve this problem?

I think you may be referring to this line?

annotorious/packages/annotorious-openseadragon/src/annotation/pixi/PixiLayer.svelte

Line 153 in 8eaf2bb

filterAnnotations((deleted || [])).forEach(annotation => stage.removeAnnotation(annotation));

Followed by

annotorious/packages/annotorious-openseadragon/src/annotation/pixi/stageRenderer.ts

Line 222 in 8eaf2bb

const removeAnnotation = (annotation: ImageAnnotation) => {

There might be room for optimization & I appreciate PRs. However, keep in mind the loop only updates the Map data structures. The actual redraw (which is the expensive operation) happens only once, after the loop.
