SVG Potracer + Qwen Image 2511 for Image to SVG

ComfyUI-ToSVG-Potracer plus Qwen-Image-Edit‑2511 is a strong combo for turning a raster character/image into clean SVG vector art by first stylizing it as high‑contrast “vector style” with Qwen, then tracing it to SVG with Potracer.​

What SVG Potracer is (in ComfyUI)

• ComfyUI-ToSVG-Potracer is a node that uses the Potrace library to convert a raster IMAGE into a 2‑color SVG (1 foreground, 1 background).

• It works best on sharp, high‑contrast, low‑color inputs: logos, silhouettes, bold line art, vinyl‑cut style assets.

What Qwen‑Image‑Edit‑2511 brings

• Qwen‑Image‑Edit‑2511 is an image‑editing model with strong geometric reasoning and style control, good at turning photos or detailed art into vector‑style illustrations while preserving identity and details.

• You can prompt it for “flat vector art illustration, bold black outline, white background, minimal shading” to prepare an ideal input for Potracer.​​

Minimal workflow idea (high level)

1. Input image (your character/logo).

2. Qwen‑Image‑Edit‑2511 node

   • Mode: image‑to‑image edit.

   • Prompt: describe target vector style (“flat 2‑color vector logo, black shapes on pure white background, thick outlines”).​​

   • Output: stylized, high‑contrast raster.

3. Optional: a simple levels/threshold step to really push it to only black and white.​

4. ComfyUI-ToSVG-Potracer node

   • Input: the processed raster image.

   • Tune Potracer params (e.g., optimize_curve, turdsize, smoothing) to control line smoothness and detail.

   • Output: SVG file (vector paths).

This way Qwen handles the aesthetic conversion to vector‑like art, and Potracer handles the true vectorization to SVG paths.
