The Item Macro-Operator
A Macro-Operator is an item which represents a group of items used as a regular item. Like items, it contains input images, mask, parameters, output images, and result value. The macro is defined by its related subgraph of items.
The group of items is composed in the related subgraph (double-click on the item to open the subgraph.)
The links between inputs, mask, parameter and outputs of the macro are done thanks to the connection slots located at the border of the subgraph:
To enable execution, each output as well as the final result must be linked before execution, even directly with inputs slots.
