Copy code
Bitmap.createBitmap(rgbaArray, width, height, config).asImageBitmap()e

There is Image.makeFromEncoded(bytes) but this expects an compressed image format.
You could use BufferedImage from Swing but i think this is not so good performance like skia.
@eygraber You know that you can also draw canvas in Compose?
