Testing the Gizmo's Tree
OK, so the functionality is there, but let's test what this looks like on an image and see if
the current tree is missing anything. Let's call it beta testing the Safe Area tool.
1. From the Image toolbox, create a ColorBars node.
TheColorBarsnodegeneratescolorbarsusedinvideoimageadjustments.Inthis
case, you will just use it as a background image for the Safe Area tool.
Now where should you connect the ColorBars node? Seems like there is already
something missing. If you connect ColorBars1 to the input of either Rectangle
node, you will pass them through the EdgeDetect and Shuffle nodes. That's not
part of the functionality planned for; you need to add another Merge node.
2. Click Text2 to select it and press M to create another Merge node.
Figure 12.29. Not every part of the Safe Area is readable.
