Convert PNG images to high-quality SVG with optional white-background removal, vtracer spline vectorization, and svgo compression. Use when the user asks for "PNG to SVG", "png2svg", "转 SVG", "矢量化", "去白底", logo tracing, or converting raster icons into editable vector assets.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 矢量描摹 · Vector Tracer
将 PNG 图片转换为高质量矢量 SVG，支持去除白色背景。
## 工具链
```
PNG → magick (去白底+alpha阈值) → vtracer (样条曲线) → svgo (压缩) → SVG
```
- **ImageMagick** (`magick`): 去除白色背景 + alpha 阈值处理
- **vtracer**: 样条曲线矢量化（比 potrace 更平滑）
- **svgo**: SVG 路径压缩优化
## 调用方式
当需要将 PNG 转换为 SVG 时，按以下步骤执行：
### 输入
- `INPUT_PNG`: 输入 PNG 文件路径（必需）
- `OUTPUT_SVG`: 输出 SVG 路径（默认：同名 .svg）
- `KEEP_BG`: 是否保留背景（默认：false，去除白色背景）
### 执行步骤
#### Step 1: 预处理（去白底）
如果需要去除背景（KEEP_BG=false）：
```bash
magick INPUT_PNG \
-fuzz 15% -transparent white \
-channel A -threshold 50% +channel \
INPUT_PNG.temp.png
```
#### Step 2: 矢量化
```bash
vtracer --input INPUT_PNG.temp.png --output OUTPUT_SVG \
--mode spline \
--filter_speckle 8 \
--color_precision 8 \
--corner_threshold 120 \
--segment_length 6 \
--path_precision 5
```
#### Step 3: 压缩优化
```bash
npx svgo OUTPUT_SVG -o OUTPUT_SVG --multipass
```
#### Step 4: 清理
```bash
rm -f INPUT_PNG.temp.png
```
### 输出
返回生成的 SVG 文件路径，并报告文件大小。
```
✓ PNG → SVG 转换完成
输入: {INPUT_PNG}
输出: {OUTPUT_SVG}
大小: {file_size}
```
## 依赖
首次使用前确保已安装：
```bash
brew install imagemagick
cargo install vtracer
npm install -g svgo # 或使用 npx
```

How to install
mdr add lovstudio/skills/lov-png2svg@sha256:24adbc9c9a78dec1The line at the top of this page pins the label v1.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
