Generate images via multiple mechanisms. Supports: (1) End-to-end AI generation via Gemini/ZenMux — given a prompt, directly output an image. (2) Code-based rendering — generate HTML/React single-file, render to PNG via Playwright. (3) Prompt engineering — generate optimized prompts for external models (nano-banana-pro, etc.).

Image Creator — Multi-Mechanism Framework

Mechanism Selection

Choose the mechanism based on user intent:

Mechanism	When to Use	Output
end-to-end	User wants AI-generated artwork, photos, illustrations	PNG image
code	User wants designed layouts (posters, cards, banners) with editable content	HTML file + PNG
prompt	User wants a prompt for external model (Midjourney, nano-banana-pro, etc.)	Text prompt

If the user doesn't specify, infer from context:

"生成一张猫的图片" → end-to-end
"做一张活动海报" → code
"帮我写一个 Midjourney prompt" → prompt

Mechanism 1: End-to-End (Gemini)

python3 gen_image.py "PROMPT" [-o output.png] [-q low|medium|high] [--ascii]

Generates image directly via Gemini 3 Pro (through ZenMux)
Requires ZENMUX_API_KEY environment variable
First run auto-installs google-genai and Pillow via pip --user (no manual setup)
Display result with Read tool after generation

Mechanism 2: Code-Based Rendering

Step 1: Generate HTML

Write a single self-contained HTML file that includes all styles inline. Use:

React 19 via CDN (https://cdn.jsdelivr.net/npm/react@19/umd/react.production.min.js)
ReactDOM 19 via CDN
Tailwind CSS via CDN (https://cdn.tailwindcss.com)
Google Fonts via <link> for CJK: Noto Sans SC, Noto Serif SC

Template structure:

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <script src="https://cdn.jsdelivr.net/npm/react@19/umd/react.production.min.js"></script>
  <script src="https://cdn.jsdelivr.net/npm/react-dom@19/umd/react-dom.production.min.js"></script>
  <script src="https://cdn.tailwindcss.com"></script>
  <link href="https://fonts.googleapis.com/css2?family=Noto+Sans+SC:wght@300;400;500;700;900&family=Noto+Serif+SC:wght@400;700&display=swap" rel="stylesheet">
  <script>
    tailwind.config = {
      theme: { extend: { /* custom theme */ } }
    }
  </script>
  <style>
    /* Reset & base styles */
    * { margin: 0; padding: 0; box-sizing: border-box; }
    body { width: {{WIDTH}}px; height: {{HEIGHT}}px; overflow: hidden; }
  </style>
</head>
<body>
  <div id="root"></div>
  <script type="text/babel" data-type="module">
    // React component here
    function Poster() {
      return (/* JSX */);
    }
    ReactDOM.createRoot(document.getElementById('root')).render(<Poster />);
  </script>
  <script src="https://cdn.jsdelivr.net/npm/@babel/standalone/babel.min.js"></script>
</body>
</html>

IMPORTANT: Babel standalone script MUST come AFTER the text/babel script block.

Step 2: Render to PNG

python3 scripts/render_to_png.py \
  /path/to/poster.html \
  -o output.png \
  -W 1200 -H 630 \
  --scale 2

Common aspect ratios:

Ratio	Dimensions	Use Case
16:9	1200×675	Social media banner
4:3	1200×900	Presentation
1:1	1080×1080	Instagram post
9:16	1080×1920	Story / mobile poster
3:4	900×1200	Portrait poster
A4	794×1123	Print poster (210mm×297mm @96dpi)

Step 3: Display & Iterate

Use Read to display the PNG
Open with open output.png on macOS
User can request edits → modify the HTML → re-render

Mechanism 3: Prompt Engineering

Generate optimized prompts for external models. Include:

Positive prompt: subject, style, lighting, quality tags
Negative prompt: common defects to avoid

Format output as copyable code block.

Reference Image Support

When user provides a reference image:

End-to-end: describe the style/composition in the prompt
Code: analyze the layout, colors, typography → replicate in HTML/CSS
Prompt: extract style keywords for the external model

Aspect Ratio

Always ask or infer the desired aspect ratio. Map to pixel dimensions using the table above.
