Hello kind reader!

I am curious to read what you think is the best approach to transfer a 5-channel image from an imageregistration node to an imageevaluation node.

Or should I do the proposed thing in the Image.msg-Definition and ask for a 8u5c-Format?

# If you want to standardize a new string format, join
# ros-users@lists.sourceforge.net and send an email proposing a new encoding.

Another idea would be to wrap 3 Image.msg (3ch-RGB + 2x 1ch-Bands) in mymsimage.msg, but isn't that much overhead for the headers? They already have the "same" position, size and timestamp after image registration.

Thank you for your consideration!
