• Camera2

• ViewからBitmap？

mTextureView.getBitmap();

arView.getDrawingCache(false);

• Bitmapを重ねるには

Bitmap offBitmap = Bitmap.createBitmap(cameraMap.getWidth(), cameraMap.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvasForCombine = new Canvas(offBitmap);
canvasForCombine.drawBitmap(cameraMap, null, new Rect(0, 0, cameraMap.getWidth(), cameraMap.getHeight()), null);
canvasForCombine.drawBitmap(overlayMap, null, new Rect(0, 0, cameraMap.getWidth(), cameraMap.getHeight()), null);
