# WeChat Image Generator

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

## Quick Start

### 1. Cover Image (封面图)
```bash
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)
```bash
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)
```bash
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)
