Onscreen Controls
When it comes to adjusting images, the Control Panel provides very precise numerical values,
but sometimes visually positioning an element using onscreen controls can get you where you
want to go with less tweaking. The viewers show onscreen controls for manipulating the
parameters of the currently selected node. Common onscreen controls include crosshairs,
angle indicators, polylines, and paint strokes. Each of these controls can be manipulated
directly in the viewer using the mouse or keyboard.
The Angle preview control.
The controls shown in viewers are determined by which nodes are selected, not by the node
displayed in the viewer. For example, a downstream blur is easily viewed while manipulating the
controls for a selected polygon mask or merge. If multiple nodes are selected, the controls for
every selected node are shown simultaneously.
Showing and Hiding Onscreen Controls
The onscreen controls for a viewer can be hidden so they don’t interfere with viewing
the image.
To toggle the visibility of onscreen controls, do one of the following:
Click a viewer’s Option menu and choose Show Controls to toggle the controls
on or off.
Right-click in a viewer and choose Options > Show Controls from the contextual menu.
Select a viewer and press Command-K.
Enabling/Disabling Onscreen Controls in Specific Nodes
Some nodes, like masks, allow disabling of their onscreen controls on a per-node basis, since
you often use multiple Polygon nodes to organize and animate masks.
You can disable some nodes, like the Polygon node, on a per-node basis.
