Hi there, I watched a youtube video about changing the shapes of pixels in a QR code and is really excited to do it. However, the video was not a clear tutorial and I am a beginner in grasshopper. Can anyone help me to figure out how to complete it? The picture attached is what I have right now. But one of the biggest problems I am facing is that the QR code image won’t show in my rhino window, and I have no idea how to make it show.
