Banner](banner.png)\n\n# Vectopus\n\nVectopus is a browser-based, client-side image-to-vector studio that converts raster images (PNG, JPG, WEBP) into scalable vector graphics (SVG) entirely in the browser.\n\n![Vectopus Interface](interface.png)\n\nThe application utilizes canvas-based image preprocessing and advanced tracing configurations to produce clean, optimized SVGs without sending any files to external servers.\n\n## Features\n\n### Interactive Viewport\n\n- **Synchronized Zoom and Pan:** Drag the workspace to pan and scroll to zoom up to 1200% to inspect vector precision directly aligned with original pixels.\n- **Split Curtain Slider:** Drag a vertical divider curtain overlay to transition between the original image and the vectorized SVG in real-time.\n\n  ![Split Curtain Preview](split.png)\n\n- **Side-by-Side Comparison:** Compare the source and vector output side-by-side inside independent, synced preview cards.\n\n### Image Preprocessing Pipeline\n\n- **Chroma Key Background Eraser:** Choose between automatic background detection (edge scanning) and custom color extraction.\n- **Interactive Eyedropper:** Click directly on the preprocessed preview to pick and erase target background colors.\n- **Chroma Tolerance Slider:** Tune the color-matching tolerance boundaries with a smooth transition feather.\n- **Contrast and Brightness Filters:** Adjust contrast and brightness sliders to isolate details or outlines.\n- **Binarization (Silhouette Mode):** Convert images into high-contrast black-and-white silhouettes before vectorization.\n\n### Advanced Tracing Engine\n\n- **Tracing Presets:**\n  - **Logo/Graphic:** Flat solid color tracing with sharp boundaries.\n  - **Detailed Vector:** High color depth mapping for complex graphics.\n  - **Silhouette:** Solid contrast-mask tracing.\n  - **Outline Sketch:** Outline contours with stroke customization.\n  - **Retro Pixel Art:** Retains sharp pixel boundaries using right-angle alignment.\n- **Custom Engine Tuning:** Adjust color count limits, despeckling noise filters, line/spline smoothing coefficients, and coordinate rounding decimal precision to control file size.\n\n### SVG Inspector\n\n- **Performance Metrics:** View input PNG file size vs output SVG file size, compression ratios, and path complexity.\n- **Markup Inspector:** View, copy, or download the raw SVG source code.\n\n## Tech Stack\n\n- **Framework:** TanStack Start (SSR React Meta-framework)\n- **Build Tool:** Vite\n- **Styling:** TailwindCSS\n- **Tracing Library:** ImageTracerJS\n- **Icons:** Lucide React\n\n## Getting Started\n\n### Prerequisites\n\nMake sure you have Node.js and npm (or Bun) installed.\n\n### Installation\n\nClone the repository and install the dependencies:\n\n```bash\nnpm install --legacy-peer-deps\n```\n\n### Running Locally\n\nRun the development server:\n\n```bash\nnpm run dev\n```\n\nOpen `http://localhost:8080` in your browser.\n\n### Building for Production\n\nTo build the application for production deployment:\n\n```bash\nnpm run build\n```\n\nTo preview the production build locally:\n\n```bash\nnpm run preview\n```\n\n##
