toggleable zoom lock feature

[matt-deboer]

Feature Request
For some scenarios where zooming is overly sensitive (I'm looking at you, Macbook pro oversized touchpad), it would be useful to toggle a lock on the zoom capability.

on large images the zoom is also quite poor.. or unclear. I find it will really help if we had a tool to move the image and annotations.

[EMCP]

performance in general is bad on large large images, but that's probably not trivial to fix either

@EMCP What version are you on. This should no longer be an issue #151

[EMCP]

according to the site, v0.8.0

I may be on the fat tail side of image sizes, can try preprocessing a step down (tried half size and still quite big)... had chrome crash on me once now, may switch to firefox as I heard it can help

@EMCP Current version is 0.10.2, issue was fixed in 0.9.0. Please consider upgrading. Keep in mind annotation made in 0.8.0 might not be optimization but new annotations will be.

[EMCP]

definitely can do! I had just run off the instructions 1 month ago, but perhaps I need to build from source to get latest release.. in either case, will do! thanks

luckily hadn't made too many datasets with the v0.8.0

[jsbroks]

To get the latest:

git pull
docker-compose down
docker-compose pull
docker-compose up

Normally you wont have to do git pull, but 0.10 was such a large update. View release section for more info on what has changed.

[EMCP]

I still get crashes, I can hear my CPU whirring hard on these images.. I'm guessing it's testing the limits of VueJS and the algorithm that stores the annotation mask cordinates

@EMCP Please try to reproduce this on the demo server and provide a link.
