Hi. I'm running ros2/demos intraprocessdemo , imagepipelinedemo. But in this demo ,the image size is too small.

When I increase the image size to 19201080 or 1280720, The msg.get() address will always change. And the communication time will increate to 15ms. And If I decrease the publish rate to 5HZ, the msg.get() address will stay the same, and the communication time will be 1ms or 2ms .

Can this demo support image size 1920*1080 at30 HZ? How to achieve this?

Thanks !
