compressed image visualizer?

[flynneva]

it looks like image_transport is being used now within rviz2....however i cant seem to get the image plugin to even list the compressed image topics, i can only see them listed in the camera rviz plugin.

are there plans to add support for compressed image topics to rviz2?

Part of the original impetus to making rviz2 use image_transport was exactly so that we could write functionality for compressed images.

That said, I don't think there are currently any concrete plans to implement that. But we'd definitely be happy to review any PRs to implement that.
