如何为捕获的图像添加水印文本

Question

我想使用水印在拍摄的图像上添加经度和纬度值，为此我在Google中搜索了很多，但是我没有找到任何解决方案可以帮助我，这是显示经度和纬度值的最佳方法捕获的图像上

private void takePhotoFromCamera() {
    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(intent, CAMERA);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
      imageView.setImageBitmap(mark(thumbnail, "Water mark text", 200, 200, Color.GREEN, 80, 24, false));
}

 public static Bitmap mark(Bitmap src, String watermark, int x,int y, int color, int alpha, int size, boolean underline) {

        int w = src.getWidth();
        int h = src.getHeight();
        Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());

        Canvas canvas = new Canvas(result);
        canvas.drawBitmap(src, 0, 0, null);

        Paint paint = new Paint();
        paint.setColor(color);
        paint.setAlpha(alpha);
        paint.setTextSize(size);
        paint.setAntiAlias(true);
        paint.setUnderlineText(underline);
        canvas.drawText(watermark, x, y, paint);

        return result;
    }
