Hey everyone, I want to add a border around a custom shape, unknown ,basically a image loaded from XML or a bunch of composables inside a Box

[Zach Klippenstein (he/him) [MOD]]

You can pass a Shape to the border modifier, and make a custom shape for whatever you need.

The problem is when the shape is unknown. I have a library that can help for that. If you have a Bitmap it can compute a Path representing the outline

See https://github.com/romainguy/pathway

That’s how I flow text around these images for instance:

That’s awesome, thanks. Is there a way we can do that with a composable función? (an image and a text)

[romainguy]

You'll have to render the composable to a bitmap first

@romainguy How do you determine the outline of a bitmap? Any sources or references you can share to explain what’s happening?
