Headless Opacity about react-native-skia HOT 3 CLOSED

This is actually the expected result.
The values are unpremultiplied when you encode it to a non transparent format, this is what you will get (only the rgb components are used).
If you want to save it as JPG, you can add a black background yourself and get the expected result.
If you save it as a PNG, the transparency will be preserved.

If you create the surface Premultiplied, you will get the expected result, which we could expose as an option but I am not sure if it's worth it 🤔

I'm closing it for now but if there is a use case for creating surfaces with more control over the color format, alpha type, and color space, we will reopen it.

That makes sense! I agree, this seems correct as the intended behavior. Thank you for clarifying for me!
