how to pan zoomed image

[stas00]

I have a very large pickle with many thousands of items, so I have to zoom in the rendering to be able to access the specific allocations, but when I do that parts of the rendering disappear and I couldn't find how to pan, so this tool is a great improvement over Chrome rendering but I can't using it without being able to pan the zoomed image. This was on Linux.

Thank you!

WASD should work, is it not working on your computer?

Wow, it's the first time I have heard of WASD - looks like a gamer thing, but from reading comments I have figured out how to use it - Ctrl+[W|A|S|D] to pan with keyboard. Learned something new - thank you. Perhaps it could be useful to add to README.md? I can make a PR.

Is there a way to add mouse window panning? For a huge pickle with lots of allocations the keyboard panning is very clunky when heavily zoomed in. It'd be much more user friendly to use a mouse. Like google maps or some such?

Thanks for the suggestion! I will try to implement mouse window panning 😄

@stas00 branch drag-pan should be kind of working; Note that now ctrl-click to view allocation details.

mouse pan works, thank you!

would it be more intuitive to reverse Ctrl+Drag to pan and keep the normal click to show trace?

somehow Chrome's https://docs.pytorch.org/memory_viz pans and mouse clicks to show trace w/o needing to use Ctrl.
