The Item: Operator
An Operator is an item which represents a binary program of the common library or the personal library.
An operator takes data from the input slots and produces new data in the output slots. The parameters are used to tune the operator behavior.
The mask is a file that specifies the region in which the operator will operate. However, this principle must be implemented by the operator itself. Ariane only add this mask file as an optional argument of the command line sent to the operating system:
name parameter* [-m mask_file] input* output*
An Operator is invoked by Ariane as a command of the operating system:
name parameter* [-m mask] input* output*
The name is the name of the binary as defined in the operator property dialog (with relative or absolute path). The mask is optional and is only introduce if the mask slot is linked.
