About

PNG to SVG Skill

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):

magick INPUT_PNG \
  -fuzz 15% -transparent white \
  -channel A -threshold 50% +channel \
  INPUT_PNG.temp.png
Step 2: 矢量化
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
npx svgo OUTPUT_SVG -o OUTPUT_SVG --multipass
Step 4: 清理
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:

brew install imagemagick
cargo install vtracer
npm install -g svgo  # 或使用 npx

参数调优

| 参数 | 作用 | 调大效果 | |-----|------|---------| | filter_speckle | 过滤小斑点 | 更干净 | | corner_threshold | 角点阈值 | 更平滑 | | segment_length | 线段长度 | 更平滑 | | color_precision | 颜色精度 | 更准确 |
