How to add contour?

[1923trk]

Hello, Thank you for the library.
I have png images with alpha channels. I want to add contours to these images and get a result like the examples I will share below, but I couldn't find how to do it. Additionally I should be able to control the background color.

There is no function to do that and I am also not sure if that is even possible. Maybe you could ask your question here instead: https://github.com/ImageMagick/ImageMagick/discussions. And if you get an answer and need help translation this to C# then feel free to come back and ask for more help.
