Image2Prompt

Analyze images and generate detailed, reproduction-quality prompts for AI image generation.

## Workflow

**Step 1: Category Detection**
First, classify the image into one of these categories:
- `portrait` — People as main subject (photos, artwork, digital art)
- `landscape` — Natural scenery, cityscapes, architecture, outdoor environments
- `product` — Commercial product photos, merchandise
- `animal` — Animals as main subject
- `illustration` — Diagrams, infographics, UI mockups, technical drawings
- `other` — Images that don't fit above categories

**Step 2: Category-Specific Analysis**
Generate a detailed prompt based on the detected category.

## Usage

### Basic Analysis

```bash
# Analyze an image (auto-detect category)
openclaw message send --image /path/to/image.jpg "Analyze this image and generate a detailed prompt for reproduction"
```

### Specify Output Format

**Natural Language (default):**
```
Analyze this image and write a detailed, flowing prompt description (600-1000 words for portraits, 400-600 for others).
```

**Structured JSON:**
```
Analyze this image and output a structured JSON description with all visual elements categorized.
```

### With Dimensions Extraction

Request dimension highlights to get tagged phrases for each visual aspect:
```
Analyze this image with dimension extraction. Tag phrases for: backgrounds, objects, characters, styles, actions, colors, moods, lighting, compositions, themes.
```

## Tips for Best Results

1. **High-resolution images** produce more detailed prompts
2. **Clear, well-lit images** yield better category detection
3. **Request structured output** when you need programmatic access to individual elements
4. **Use dimensions extraction** when building prompt databases or training data
5. **Specify word count expectations** for natural language output if needed
