Shape's outline color from a table column
Currently, the color of a set of shapes can be set according to a column in the table, but for the outline, it's only possible to specify a single color common to all shapes.
I would like to propose the possibility to select different outline colors for different shapes.
My use case is that I automatically generate annotated regions around certain groups of cells and I want to display only the outline because these regions can contain heterogeneous cells (colored + grey) that I still want to be able to show, as in the example in the following image.
If you think it's a good idea I can attempt a PR :)
Hi @marcovarrone, the addition of this feature would very nice, if you could propose a PR it would be super! We are happy to review it and assist you with technical questions.
btw should also specify that you can achieve something similar by using the contour argument, instead of the outline, which leverages https://scikit-image.org/docs/stable/api/skimage.morphology.html#skimage.morphology.erosion
