Export Volume Annotations

[fm3]

Note that #5252 should be merged first (some of the bugs fixed there could crop up here too during testing)

TODO (includes changes in https://github.com/scalableminds/webknossos-worker/pull/6/ )

• fetch volume annotations
• merge with fallback layer
• pass result to cuber
• are compound tracings cached long genough? → increased to 70 min, created follow-up issue In Tracingstore, move temporary data from local cache to Redis #5255
• use glob instead of exists
• pass version
• pass token only for this job
• pass tracing id from frontend
• don’t include fallback layer if it is unlinked
• test resulting files with imagemagick (convert 000002.tiff -evaluate multiply 200 -depth 8 8.tif)
• adapt job description in list view
• disable buttons already in frontend if mag1 is not present
• ensure saved state
• clean up intermediate files? (let’s leave them in for the moment, for debugging. clean-up job issue Add expiry + clean up job for exported files #5202)

Steps to test:

• set up https://github.com/scalableminds/webknossos-worker/pull/6/
• set jobsEnabled = true in application.conf
• open volume annotation (also try hybrid, skeleton, view mode)
• brush some, create bbox
• click export tif button, modal should show annotation layer
• zip download from jobs list should include segmentation tifs with the annotations
• modals should not contain typos

Issues:

• fixes Tiff Export for Volume Annotations #5203

---

• Updated (unreleased) changelog
• Ready for review

Another idea: might be worth to save the “referrer” link with the job (e.g. to go back to the source (compound) annotation the tiffs were exported from. The tracing id is not sufficient for this lookup in compound case.

Edit: created follow-up issue for that #5261

front-end looks great! will test now.

I have not tested it, but the backend code looks good 🎉
