I noticed that in github, autoresize functionality was added in v4.3.0: https://github.com/eXeC64/imv/commit/4eaa1c89aefb4ebb0cc5aa40613a555e6d250ed0
However, in v4.3.1 and master, this functionality doesn't seem to exist. Adding autoresize to the config, or using -w flag returns an error. Checked the source code too, and there doesn't seem to be any autoresize functionality.
Unless there are reasons for removing this functionality, it would be great to have this option.
Thank you so much.
Looks like I temporarily removed it as this kind of functionality wasn't (and may still not be) possible in wayland, and then forgot about it completely. I'm fine with the feature but it'd need to be rewritten from scratch most likely, and that's if there's a wayland protocol to allow this.
