2014-06-24 07:22:49 -0500 asked a question ueye: how to publish only compressed image?

I'm using the ueye package and I want to reduce the number of published messages. Since I'm only using the compressed images, I don't want the node to publish them additionaly in raw and theora. Is there an easy way to change this? I've tried the parameter _image_transport:=compressed. But it's only working for the subscriber not for the publisher.

Btw, I'm using hydro on Ubuntu 12.04.4.
