CMS Logo Sprite Sheet

This directory contains tools to build a sprite sheet of monochrome logos for open source platforms.

Quick Start

cd presentations/ca-slides/assets
python3 build-logo-sprite.py

This will:

1. Download logos from the URLs in logo-sources.json
2. Convert them to monochrome (black and white)
3. Create a sprite sheet in cms-logos.svg

Adding New Logos

Edit logo-sources.json and add entries to existing categories or create new ones:

{
  "cms": [
    {
      "name": "New CMS",
      "description": "Description of the platform",
      "url": "https://example.com/logo.svg"
    }
  ]
}

Categories are semantic groups like:

• cms - Traditional content management systems
• headless_cms - Headless/API-first CMS platforms
• static_site_generators - Static site builders
• frameworks - Web frameworks
• social_platforms - Social networking platforms
• learning_platforms - Educational platforms

Removing Logos

Simply delete the entry from logo-sources.json and re-run the script.

Finding Logo URLs

Best sources for open source project logos:

• Wikimedia Commons: https://commons.wikimedia.org/
• Official project websites (look for press/media kits)
• GitHub repositories (often in /docs or /assets)

Make sure to use SVG format when possible for best quality.

File Structure

• logo-sources.json - Configuration with logo URLs

License Considerations
