Tableau Method

Allows multiple operators to be manipulated simultaneously in a pipeline architecture; outputs of operators are connected to inputs of other operators

Starting the system presents a blank workspace.

File operations allow the user

Clear the workspace
Save the workspace
Load a previously stored network

Components menu allow the user to choose an operator to add to the workspace

Component appears as a rectangle with the name of the operator and labels for input and output

Operators can be repositioned on the workspace by left-button dragging
Parameters can be set for the operator by double-clicking on the operator name
Operators can be deleted by right-clicking on the operator name

Building a network

Always should start with an "ImageLoad" component
Probably end with "ImageDisplay" component
Click on an "output" and drag to an "input" to establish a connection
Output can go to multiple destinations; Input can only be received from one location
Avoid Loops! (system will hang)
