WeChat Image Generator

Generate beautiful images for WeChat articles with zero token cost and auto-screenshot.

Quick Start

1. Cover Image (封面图)

python3 scripts/generate.py cover \
  --title "我的第一个开源项目" \
  --subtitle "Token 成本降低 90%" \
  --output output/cover.png

2. Comparison Image (对比图)

python3 scripts/generate.py compare \
  --left "# Markdown\n**Bold** text" \
  --right "HTML 渲染结果" \
  --label "1 秒转换" \
  --output output/compare.png

3. Chart Image (数据图)

python3 scripts/generate.py chart \
  --data "Token消耗:8000,650|生成耗时:20,1" \
  --labels "AI生成,预制模板" \
  --output output/chart.png

Workflow

1. Run generator script with parameters
2. Script creates HTML with embedded data
3. Opens in browser via OpenClaw browser tool
4. Auto-screenshot and save to output folder

Design Philosophy

Zero token cost: All templates are pre-built HTML/CSS Auto-screenshot: Integrated with OpenClaw browser tool Customizable: Easy to modify templates for different styles

Token Cost Analysis

Per image generation:

• Read SKILL.md: ~500 tokens (first time only)
• Execute script: ~100 tokens
• Browser screenshot: ~50 tokens

Total: ~650 tokens vs DALL-E/Midjourney ~1000-5000 tokens per image.

Requirements

• Python 3
• OpenClaw browser tool (for auto-screenshot)
