Create Line art (silhouette or contour drawing) from filled shapes on colour layer

Hi Folks,

I know there has got to be some way to do this in harmony. In photoshop if I have a layer of filled painted shapes and want to create a separate line layer I control click the layer to get a selection around the shape. Then I simply select the brush tool, go to the menu options and pick ‘stroke selection’. This puts a drawn line around any area that was selected, including negative shapes or holes inside the shape. How would I do a similar thing in Harmony? Any help would be super appreciated :slight_smile:
