How it helps

Generate a circular pin-and-thread portrait from a local image.

Tune pin count, line count, frame diameter, crop, contrast, gamma, and thread darkness.

Export a production package with DXF, SVG, PNG, CSV, TXT, and metadata.

Runs locally in the browser with no photo upload.

- Use a close, high-contrast portrait with clear light and dark facial features.
- Start with 200-280 pins and 1800-3000 lines for physical work.
- Cut or mark the pin circle accurately before following the exported pin sequence.
- Test a small line count first if your material, pin size, or thread thickness is unfamiliar.

- V1 is single-color black thread on a light background; multi-color thread is planned for a later version.
- The DXF is a pattern and reference drawing, not a robot or G-code fabrication path.
- Very low-contrast photos may need manual contrast/crop adjustment before the result is recognizable.

No. The portrait is processed locally in your browser and the production files are generated on your device.

Use the TXT or CSV pin sequence for wrapping the thread, and use the SVG or DXF to mark the frame and numbered pins.

Yes. The DXF contains FRAME, PINS, and THREAD layers for CAD, laser marking, or reference layouts.

Not in v1. The output model is prepared for future multi-color threads, but this first version produces one black-thread sequence.
