limit z range for mouse scrollwheel

[berl]

Currently neuroglancer will allow you to ctl-scroll in z well outside the range of any image stacks. I'm working with stacks that are just a few images deep and it's easy to end up far away from the data. I'd love to see scrollable z range to the z limits of the data (maybe padded with 1 slice to make people feel good about reaching the end). Thanks!

This feature makes sense --- are you interested in trying to implement it?

This is probably not a good job for me, given that I had to google what .ts is! From poking around, maybe it could be implemented by adding a check in the SpatialPosition class . The validity of the new z position is checked (i.e. is it null?) before updating it and there could be a new method added to the SpatialPosition class to check if it's in the z limits of any current stack. It's possible such a method could also be useful for annotation tasks and allowing the user to toggle display of annotation objects inside or outside the image data volume.

At long last, this has been implemented as part of the general improvements to the handling of coordinate spaces in Neuroglancer.
