ROS2 image_transport republish broken?

[Ken Yasumoto-Nicolson]

Using Foxy on Ubuntu 18.04:

I use the command:

ros2 run image_transport republish compressed --ros-args --remap in:=/camera3/front/image_raw --remap out:=/camera/image_repub

I expect to see /camera/image_repub/compressed appear, but it is not being published.

EDIT: I see I am mistaked; the first argument compressed is the input format, but this topic is uncompressed, and there doesn't seem to be a NULL topic; I would need a image_raw_sub to satisfy the current structure.

I'm deleting the rest and closing.
