SVG Icon Maker

Convert raster images to colorful SVG using @neplex/vectorizer.

Output Directory

All files saved to workspace with timestamped folders (format: YYYY-MM-DDTHH-mm-ss-SSSZ):

<workspace>/svg-output/
└── <timestamp>/              # e.g., 2026-01-27T02-13-38-811Z
    ├── reference.png         # Generated reference image
    ├── icon.svg              # Color SVG output
    └── icon_preview.png      # Preview for comparison

Prerequisites

cd <workspace>
npm init -y
npm install @neplex/vectorizer sharp

Workflow

Step 1: Generate Reference Image

Use generate_image tool, save to svg-output root first (or directly to output folder if managed manually):

# Generate image, then move to proper folder later or keep in root for processing

Prompt template:

"[subject] avatar, high fidelity vector illustration, clear line style, 
black closed outlines, flat uniform colors, no gradients, 
white background, distinct separation between colors"

Step 2: Convert to Color SVG

Run the conversion script directly from skill resources (no copying needed):

node .agent/skills/svg-icon-maker/script/convert-template.js <input-file> [output-dir]

Example:

# Using default output directory (./svg-output)
node .agent/skills/svg-icon-maker/script/convert-template.js ./my-image.png

# Specifying custom output directory
node .agent/skills/svg-icon-maker/script/convert-template.js ./my-image.png ./custom-output

Key Features:

  • 4-Corner Flood Fill: Removes background starting from all corners to handle split backgrounds.
  • Inner Detail Protection: Preserves white/light details inside the subject (e.g., eyes).
  • Auto-Threshold: Adapts to the specific background color found at the corners.
  • Timestamped Output: Automatically creates folders with format YYYY-MM-DDTHH-mm-ss-SSSZ.

Step 3: Verify & Compare

ls -la <workspace>/svg-output/

Use viewfile to compare reference.png with iconpreview.png.

Parameters

Default settings optimized for HIGH color fidelity - preserves original colors, only removes background.

Parameter Default Description
colorMode Color ColorMode.Color or Binary
colorPrecision 8 1-8, higher = more colors (8 = max fidelity)
layerDifference 8 Color layer threshold (lower = less merging)
filterSpeckle 4 Remove noise pixels (lower = more detail)
mode Spline PathSimplifyMode.Spline or Polygon
cornerThreshold 60 Corner detection angle
spliceThreshold 45 Spline angle threshold
