Continuously zoomable images #360

Closed wafels closed 2 months ago

wafels commented 2 years ago

This image:

https://www.sidc.be/EUI/pictures/20220307_hrieuv_mosaic/

is continuously zoomable and relies on this library:

http://openseadragon.github.io/

Should this be implemented in Helioviewer, and if it is, how would this affect the screenshot and movie making capability? And positioning of features and events....

Features and events are doable:

A typical helioviewer viewer window would include multiple layers, features and events and labels. Transparency also needs to be included in order to make sure that the Sun is visible in the center of coronagraph images.

Since we have code to handle this for mobile, I can likely leverage the same code for handling zoom but connect it to the mouse wheel.

We could also still explore openseadragon. I think I have some notes from playing with openseadragon before.

We have continuous zoom now.
