Introduction to Multi-Image Composition
Multi-image composition blends visual assets together to create new visuals. With Nano Banana API and the Gemini multi image endpoint, developers can perform style transfer and merge scenes creatively.
Overview of Nano Banana API and Gemini Multi Image Capabilities
The Nano Banana platform provides robust image processing with style transfer and multi-image merging. Leveraging the Gemini engine, you can process multiple images concurrently.
Official Site: Nano Banana API
Base URL: https://wisdom-gate.juheapi.com/v1
API Features
- Multi-image input support.
- Style transfer using advanced machine learning models.
- Scene merging with layer control.
Core Concepts: Style Transfer and Scene Merging
Style transfer applies one image's visual style to another. Scene merging combines multiple images into a single coherent scene.
Key Difference:
Style transfer modifies pixel characteristics to match the style reference, while scene merging aligns and blends multiple sources to form a composite.
Setting Up Your Environment
Before calling the API, prepare your API key from the Nano Banana dashboard.
Dependencies:
- curl or HTTP client library for your language.
- Image files for source and target.
Style Transfer Walkthrough
Choosing Source and Target Images
Select a source image with the style you desire (e.g., a painted background) and a target image to apply that style to.
API Request Parameters
Send both images as multipart/form-data or encoded references.
Example using curl:
curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--header 'Accept: */*' \
--header 'Host: wisdom-gate.juheapi.com' \
--header 'Connection: keep-alive' \
--data-raw '{
"model":"wisdom-vision-gemini-2.5-flash-image",
"messages": [
{
"role": "user",
"content": "Apply the style of image A to image B"
}
]
}'
Handling Output
The API returns a processed image URL or binary data. Save it or pipe to your CDN.
Scene Merging Walkthrough
Defining Scene Layering Logic
Identify foreground, background, and midground images. Specify their positions and z-order.
Blending Techniques
Use soft masks for natural blend or sharp edges for collage effects.
Fine-Tuning Merged Scenes
Adjust color balance and lighting to match layers for realism.
Creative Use Cases
Game Character Variations
Generate multiple skins for characters by merging base models with thematic styles.
Virtual Scene Composition
Combine real-world images with virtual assets for immersive environments.
Marketing Visuals
Quickly assemble product shots into themed campaigns using style-driven backgrounds.
Performance and Optimization Tips
- Batch process images to reduce API calls.
- Use optimized image sizes to speed up responses.
- Cache style patterns for reuse.
Error Handling and API Limits
- Monitor API quota usage.
- Handle HTTP and application-level errors gracefully.
Deployment Considerations
Integrate image processing workflows into CI/CD pipelines for consistent output quality.
Conclusion
With the Nano Banana API and Gemini multi image capabilities, developers can transform standard visuals into creative compositions for games, marketing, and virtual experiences.
