[Feature-Request] {Publishing compressed images}

[Serafadam]

Start with the why:

Describe why this feature would be useful to you and to other users. As mentioned in one of the comments, when using low_bandwidth_mode, images get converted back to "raw" message types for publishing. This introduces some additional processing which might not be needed if a user only wants to use just the compressed type.

Move to the what:

A clear and concise description of the feature you would like to get added to the depthai. Add the option to publish just the compressed images, without conversion.

Move to the how:

If you already have an idea of how this new feature could be implemented, describe it here.

• Modify ImageConverter to provide conversion to CompressedImage type
• Add compressed publishers to depthai_ros_driver (most likely will need to create a Publisher wrapper to simplify the API
• Add parameters to toggle the compression for Image publishing nodes

Is this already implemented in ROS Noetic? When I use your Noetic branch, I can recieve JPEG compressed images using the depthai_examples as well as the depthai_ros_driver launch files. I cannot get it to do PNG compression though.
