Capture Area

In this example I use a graphicsLayer to store the draw action in drawWithContent scope

val graphicsLayer = rememberGraphicsLayer()

Box(
    modifier = Modifier
        .fillMaxSize()
        .drawWithContent {
            graphicsLayer.record {
                this@drawWithContent.drawContent()
            }
            drawLayer(graphicsLayer)
        }
) {  }

finally we can extract the bitmap from graphicsLayer

graphicsLayer.toImageBitmap().asAndroidBitmap()
