Grouping Nodes

You can group an arbitrary set of nodes, whether connected or not, as another method of organizing the process tree.

Grouping is local to the Schematic view, so it is not reflected in the Workspace panel. The flow of image data is not changed by grouping. You can group nodes as a step in your workflow.

To group nodes:

1. Select the nodes to be grouped.
2. Right-click (Windows) or Ctrl-click (Macintosh) and choose Group Nodes, or press G.

The nodes are grouped into one node which is named Group. This type of node has no thumbnail.

Note: You can also press Ctrl+G (Windows) or Command+G (Macintosh).

To ungroup a group node:

1. Select the group node.
2. Right-click (Windows) or Ctrl-click (Macintosh) and choose Ungroup Nodes, or press U.

The nodes are ungrouped.

Note: You can also press Ctrl+U (Windows) or Command+U (Macintosh).

To view the contents of a group node:

Do any of the following:

• Ctrl-click (Windows) or Command-click (Macintosh) the group node.
• Double-click the group node.
• Right-click (Windows) or Ctrl-click (Macintosh) the group node and choose Edit Group Node.

The Schematic view switches to show only the contents of the group. Edges that link to nodes outside the group are connected to dummy nodes.

You cannot break the connection to a dummy node, or delete the dummy node.

Note: The connection nodes for layers belong to their Composite operator node. Thus, you cannot include layer nodes in a group without including the Composite node. When you include a Composite node, all the layer nodes are grouped with it (even if not selected).

You can group a set of nodes that includes a group node. This creates nested groups.

To return to the previous Schematic level:

• Shift-click the gray area away from the nodes.
• Right-click (Windows) or Ctrl-click (Macintosh) in an empty area of the Schematic view and choose Exit Group Node.
• Double-click or Ctrl-click on any dummy node.

The Schematic view switches to show all nodes at the next higher level (including the group node).
