image_proc/resize subscribes to image and camera_info messages using image_transport, but cannot receive messages via compressed or compressedDepth (or any non raw) transports.

[repro]

1. Publish image and camera_info with image_transport_plugins such as compressed_image_transport:

$ rostopic list
/camera_info
/image_raw
/image_raw/compressed
:

2. Subscribe to /camera/image_raw/compressed in image_proc/resize nodelet.

$ rosrun nodelet nodelet standalone image_proc/resize image:=/image_raw camera_info:=/camera_info _image_transport:=compressed

[expected behavior]

• image and camera_info are republished respectively at /image_proc_resize/image and /image_proc_resize/camera_info. Images are not resized because the default scale is 1.

[actual behavior]

• /image_proc_resize/image and /image_proc_resize/camera_info are advertised but do not publish any message.

Can you post an example message you’re sending over the compressed topic with the image data itself clipped?
