fvnet - Man Page
Explore and retrieve from FireVision instances on the network
Synopsis
fvnet -e fvnet -s -n host[:port]] fvnet <-i|-j|-c|-C> -n host[:port]]/id file
Description
Explore FireVision instances on the network and interact with those instances. In the first form the network is explored using mDNS-SD service discovery to find FireVision Fountain instances. These are then queried for existing images and lookup tables.
In the second form the available images and lookup tables are queried from a specified host.
The third form finally allows for retrieving images and retrieving or pushing colormaps reading from or writing to file.
