Convert drawing to stl file

ColorTracer is a tool designed to extract and refine image contours based on color sampling from foreground and background areas. It allows users to calibrate real-world scales, compute foreground-background probability, and generate a cleaned binary mask for edge refinement. The process includes detecting sharp corners and simplifying contours for cleaner export, with options for subpixel accuracy and morphology cleanup. The final output can be downloaded, including options for STL thickness adjustment.
