How can I overlay two outlines on a single image?


I want to use “Overlay Outlines” module to overlay two outlines on a single raw image. While I was trying to color code the two outlines separately, one color became hidden behind of the other. How can I distinguish and visualize two outlines that are different in colors on a image?


Unfortunately, that’s not doable right now. You commonly see this in IdentifySecondary where the secondary object is identical to the primary one; in that case, you see just the secondary outline because it’s the last one drawn. So in OverlayOutlines, you might consider rearranging the outline order to ensure that the outline you need to see is on top.

That said, I can imagine some way to make this case more illustrative. I’ve added it as a feature request here: … ssues/1300
