A Multi-Port-In module is added by default in a new Group module. Use it to add one or more input ports to the Group module so that you can process an image through the modules in the Group module.
When you plug an element to a Multi-Port-In module, an input port appears at the top of the Group module. You can add additional ports to the modules as needed.
Pass your cursor over the Group module input port to see the name of the Port Image In module that it connects to. You will notice that the Group module in these examples has no output port. It requires a Multi-Port-Out module to output data from its network.
A Multi-Port-In is automatically added when you create a group.
Use the Multi-Port-In editor to rename the module.
