# Nano Banana Pro

Image generation skill powered by Google's Gemini 3 Pro Image model. Enables text-to-image generation, image editing, multi-image composition, and real-time data visualization.

## Requirements

- `GEMINI_API_KEY` environment variable set
- Python packages: `google-genai`, `Pillow`

Install dependencies:
```bash
pip install -r requirements.txt
```

## Quick Start

### Generate an Image

```bash
python scripts/generate_image.py "A cat wearing a wizard hat" cat.png
```

### Edit an Existing Image

```bash
python scripts/edit_image.py photo.png "Add a sunset to the background" edited.png
```

### Compose Multiple Images

```bash
python scripts/compose_images.py "Create a group photo in an office" team.png person1.png person2.png
```

## Available Scripts

| Script | Purpose |
|--------|---------|
| `generate_image.py` | Text-to-image generation |
| `edit_image.py` | Edit/modify existing images |
| `compose_images.py` | Combine up to 14 reference images |
| `chat_image.py` | Interactive multi-turn refinement |
| `search_grounded_image.py` | Generate images with real-time search data |

## Generation Options

### Aspect Ratios
`1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9`, `21:9`

### Resolutions
`1K` (1024px), `2K`, `4K`

### Usage with Options

```bash
python scripts/generate_image.py "Futuristic motorcycle on Mars" mars.png --aspect 16:9 --size 4K
```

## Task Workflows

### Logo Generation

```bash
python scripts/generate_image.py "Clean black-and-white logo with text 'Daily Grind', sans-serif font, coffee bean icon, minimalist style" logo.png --aspect 1:1
```

### Product Mockup

```bash
python scripts/generate_image.py "Studio-lit product photo on polished concrete, 3-point softbox, 45-degree angle, professional e-commerce style" product.png --aspect 4:3 --size 4K
```

### Photorealistic Portrait

```bash
python scripts/generate_image.py "A photorealistic close-up portrait, shot on 85mm lens, golden hour lighting, shallow depth of field, cinematic" portrait.png --size 4K
```

### Stylized Art (Anime/Sticker)

```bash
python scripts/generate_image.py "A kawaii red panda sticker, bold outlines, cel-shading, white background, cute expression" sticker.png
```

### Iterative Design Refinement

Use the chat script for back-and-forth refinement:

```bash
python scripts/chat_image.py
```

Then interact:
```
> Create a logo for 'Acme Corp'
[Image generated]
> Make the text bolder and add a blue gradient
[Refined image]
> save acme_logo.png
```

### Real-Time Data Visualization

Generate infographics with current data:

```bash
python scripts/search_grounded_image.py "Visualize today's weather in Tokyo as an infographic" tokyo_weather.png --aspect 9:16
```

Use cases:
- Live stock-market infographics
- Breaking-news visuals
- Weather dashboards
- Current event visualizations

### Multi-Image Composition

Combine reference images:

```bash
python scripts/compose_images.py "Create a product comparison shot with these items side by side, professional lighting" comparison.png item1.png item2.png item3.png --aspect 16:9
```

Use cases:
- Product comparison shots
- Character sheets
- Team photos
- Style-consistent image series

## Inline Python Usage

For integration in larger scripts:

```python
import os
from google import genai
from google.genai import types

client = genai.Client(api_key=os.environ["GEMINI_API_KEY"])

response = client.models.generate_content(
    model="gemini-3-pro-image-preview",
    contents=["A serene mountain landscape at dawn"],
    config=types.GenerateContentConfig(
        response_modalities=['TEXT', 'IMAGE'],
        image_config=types.ImageConfig(
            aspect_ratio="16:9",
            image_size="2K"
        )
    )
)

for part in response.parts:
    if part.inline_data:
        image = part.as_image()
        image.save("landscape.png")
```

### Editing with Inline Code

```python
from PIL import Image
from google import genai
from google.genai import types

client = genai.Client(api_key=os.environ["GEMINI_API_KEY"])
img = Image.open("input.png")

response = client.models.generate_content(
    model="gemini-3-pro-image-preview",
    contents=["Add dramatic clouds to the sky", img],
    config=types.GenerateContentConfig(
        response_modalities=['TEXT', 'IMAGE']
    )
)
```

## Prompting Tips

**Photorealistic**: Include camera settings, lighting, lens details
```
"Shot on 85mm lens, golden hour lighting, shallow depth of field"
```

**Logos**: Specify style, colors, typography
```
"Clean minimalist logo, sans-serif font, monochrome, vector style"
```

**Product shots**: Describe studio setup
```
"Studio-lit, 3-point softbox, polished surface, 45-degree angle"
```

**Stylized art**: Name the style explicitly
```
"Anime style, cel-shading, bold outlines, vibrant colors"
```
