  auto buf = ImageBuf("/root/oiiovuln/1.psd");
  for (auto layer = 0; layer < buf.nsubimages(); layer++) {
    // buf.reset("/root/oiiovuln/1.psd", layer);

    std::cout << buf.ymax() << std::endl;

Closing as it is not an issue: some people prefer expanding everything, some don't.
You can edit the context layout using gef config context.layout and customize to your own preference (for example just calling bt).
