Save Segmentation Image

Hello,

I’m currently trying to write my own application to save .png images received from Isaac Sim on the disk. It works well for color images. But when i try to save depth or label images i get this error:

“PANIC ./engine/alice/hooks/message_hook.hpp@199: No message available”

Here is my code :

Where rx_segmentation_image() channel receives message from type SegmentationCameraProto.

I use application navsim_training.subgraph.json to stream the different image types from Isaac Sim and i can visualize the received images in isaac sight.

Thanks in advance.
