val surface = Surface.makeRasterN32Premul(640, 360)
val canvas = surface.getCanvas()
canvas.clear(0xFFFFFFFF.toInt())
canvas.drawTriangles(
    arrayOf(Point(320f, 70f), Point(194f, 287f), Point(446f, 287f)),
    listOf(0xFF00FFFF, 0xFFFF00FF, 0xFFFFFF00).map { it.toInt() }.toIntArray(),
    Paint()
)
Image(ImageIO.read(ByteArrayInputStream(surface.makeImageSnapshot().encodeToData()?.getBytes())))

This looks just great as is but maybe there can be tweaks you can add before having Skija listed in readme like providing some shorthand for image display or not.

tbh I wanted to file this so I won't lose this code and get some feedbacks so feel free to close this with no action as the situation looks just great as is. Thanks!

So let's close this as no action was required from the beginning except a possibility to add to the list of supported which will be up to maintainers. Thanks! :)
