Gradient-Based Edge Detector USE TURBOWARP Press SPACE to scan an image and reveal its edges. This project takes a selected backdrop image and processes it through a multi-pass pixel scanning system. Each pixel is captured, stored in lists, converted to grayscale, and then processed using a custom edge detection filter based on intensity differences between neighboring pixels (similar to an Image gradient). The result is a real-time edge rendering effect built entirely in Scratch. How to use: Import your image as a backdrop Use the RIGHT ARROW key to cycle through backdrops and select your image Press SPACE to begin scanning Wait for processing to complete, then view the edge output Features: Multi-pass scanning system for improved accuracy Custom pixel data storage using lists Grayscale conversion pipeline Pen-based rendering of detected edges Notes: Best results with high-contrast images and clean shapes Complex images may produce noise due to Scratch performance limits Processing time depends on image size and detail level Credits: Inspired by pixel scanning techniques from @griffpatch Built and extended with custom edge detection logic
