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

bash

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):

bash

# 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):

bash

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

Example:

bash

# 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

bash

ls -la <workspace>/svg-output/

Use

view_file

to compare

reference.png

with

icon_preview.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
