► Instructions: This project converts images to lists you can then draw using pen. You can replace the "Canyon" backdrop with any other image before scanning. Use the "+" and "-" buttons to change resolution. It's recommended to choose a low resolution because higher resolutions are very slow (scanning at 60x45 takes less than 5 minutes, scanning at 480x360 takes 15-20 minutes). ► Performance: Compared to a similar project by @Layzej ( https://scratch.mit.edu/projects/66980580/ ), this one is much faster at lower resolutions. I scanned the same image in both projects at 60x45 resolution. In this project it took 120 seconds and in @Layzej's project it took 340 seconds. Update (January 2021): Small fix that should make the scanning part about twice as fast. Processing is still slow, I'm going to remove it in a future version. ► Credits: Thanks to @Layzej for the idea and basic algorithm.
