Change jpeg quality #108

Closed JeremieBourque1 closed 3 years ago

JeremieBourque1 commented 3 years ago

Hi,

Is there a way to change the jpeg quality for the compressed image topic? By default it is set to 80 but I don't see a parameter for changing it.

Thank you

Yeah, you can use dynamic reconfigure to change the compression level from the compressed image_transport plugin:
