2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Create SVG images and convert them to PNG without external graphics libraries. Use when you need to generate custom illustrations, avatars, or artwork (e.g., "draw a dragon", "create an avatar", "make a logo") or convert SVG files to PNG format. This skill works by writing SVG text directly (no PIL/ImageMagick required) and uses system rsvg-convert for PNG conversion.

SVG Draw

Generate vector graphics and raster images using pure SVG code and system conversion tools.

Quick Start

For new drawings:

Write SVG code directly to a file (use templates in assets/ as starting points)
Convert to PNG using the conversion script
Send via the appropriate channel (DingTalk, Telegram, etc.)

For existing SVG files:

Use the conversion script to convert SVG → PNG
Share the resulting image

Creating SVG Images

Basic Workflow

Choose or create a template
- Check assets/ for existing templates (dragon, lobster, etc.)
- Or write SVG from scratch

Write the SVG file

# Example: Write SVG to file
write('/path/to/output.svg', svg_content)

Convert to PNG

/root/.openclaw/workspace/skills/svg-draw/scripts/svg_to_png.sh input.svg output.png 400 400

SVG Structure Tips

Always include:

<svg> tag with xmlns="http://www.w3.org/2000/svg" and viewBox
Background <rect> (prevents transparent backgrounds)
Appropriate width and height attributes

Common SVG elements:

Shapes: <rect>, <circle>, <ellipse>, <polygon>, <path>
Text: <text> with text-anchor="middle" for centering
Colors: Use hex codes or named colors
Opacity: Add opacity attribute for transparency effects

Example character structure:

Background → Body → Head → Face features → Limbs → Accessories → Name

Converting SVG to PNG

Use the bundled conversion script:

/root/.openclaw/workspace/skills/svg-draw/scripts/svg_to_png.sh <input.svg> <output.png> [width] [height]

Parameters:

input.svg: Source SVG file path
output.png: Destination PNG file path
width: Output width in pixels (default: 400)
height: Output height in pixels (default: 400)

Example:

/root/.openclaw/workspace/skills/svg-draw/scripts/svg_to_png.sh dragon.svg dragon.png 512 512

Available Templates

Dragon Template (`assets/dragon_template.svg`)

Blue dragon with:

Serpentine body with wings
Golden eyes with highlights
Horns and pointed ears
Curved tail
Magical sparkles
Name label: "大龙 🐉"

Customization ideas:

Change fill="#4a90d9" for different body colors
Adjust eye color by modifying fill="#ffcc00"
Add/remove features (scales, fire, etc.)
Change background color

Lobster Template (`assets/lobster_template.svg`)

Red lobster with:

Orange-red shell with segments
Large claws (left and right)
Eight walking legs
Eyes on stalks
Long antennae
Tail fan
Ocean bubbles background
Name label: "大龙虾 🦞"

Customization ideas:

Adjust shell color: fill="#e85d04" (darker red) or fill="#f48c06" (orange)
Change claw size or position
Add more bubbles
Modify background

Design Guidelines

Color Palettes

Friendly/Cute:

Body: #4a90d9 (blue), #f48c06 (orange)
Accents: #ffcc00 (yellow), #ff6b6b (coral)
Background: #1a1a2e (dark blue)

Professional:

Use muted tones
Stick to 2-3 main colors
Add subtle gradients if needed

Character Design Principles

Keep it simple — Too many details look messy at small sizes
Use contrast — Light features on dark backgrounds
Add personality — Eyes, expressions, small details
Include a label — Add name/title at the bottom for context
Test at target size — View at 400x400 to check readability

Common Tasks

Creating an Avatar

Start with a template that matches the vibe (dragon, lobster, etc.)
Modify colors and features
Add personal touches (accessories, expressions)
Add name label at bottom
Convert and send

Making a Logo

Use simple geometric shapes
Limit to 2-3 colors
Consider scalable design
Test at multiple sizes
Export at higher resolution (800x800 or 1024x1024)

Customizing Templates

Change colors: Find fill="#" or stroke="#" attributes and replace the hex codes

Resize elements: Adjust rx, ry (ellipses) or width, height (rectangles)

Reposition: Modify cx, cy (circles/ellipses) or x, y (rectangles)

Add text:

<text x="200" y="370" font-family="Arial, sans-serif" font-size="24" font-weight="bold" fill="#ffcc00" text-anchor="middle">Your Text</text>

Troubleshooting

SVG not rendering:

Check for proper <svg> tag with xmlns attribute
Ensure viewBox is set correctly
Verify all tags are closed

Conversion fails:

Confirm rsvg-convert is installed: which rsvg-convert
Check file paths are correct
Verify SVG syntax is valid

Image looks wrong:

Test SVG in browser first
Check coordinate system (viewBox vs width/height)
Verify element stacking order (later elements draw on top)
