[Rock-dev] image_preprocessing -> DepthImage2Pointcloud callback method never called?

[Martin.Azkarate at esa.int]

Hi there,

Thanks a lot for your comments, my version of the component [stable] does 
not include any transformer in the .orogen task description, should I get 
the master version with the transformer part?

I was checking the status of the stream aligner and it seems like it drops 
samples indeed...here an snapshot of what I have:

any ideas?

Thanks again,

Hey. FYI the best way to check if the problem is related to
transformer/stream aligner is to check the two related status ports
(don't have the names out of the top of my head).
