Each Recipe step outputs either an grayscale, or B/W image. B/W images are often the goal, as the black pixels represent the selection at that point in the Recipe. If you are only targeting one set of features, a final B/W image is all you need. However, if you need to identify multiple feature types (e.g., large vs. small particles), Layers come in very handy.
Layers are essentially “favorited” Recipe steps, which can be overlaid together and measured separately. For example, if you’re looking for large vs. small particles, you may have one step which selects the large, and one which selects the small. Just set each step as a Layer, and you’re done. You’ve now separately classified your two feature types and can enjoy coloring them separately, outputting each selection during a batch process, and taking measurements from each with one click.
To move a Layer from one step to another, select then Layer step, hold CTRL and select the step to move to. The “Set Layer” button will change to “Move Layer”. Click this button to move the layer.
