FAQPage Schema
How do I generate images from text prompts using the Gemini API?

To generate images from text prompts using the Gemini API, you need a valid GOOGLE_API_KEY or GEMINI_API_KEY. The tool processes your text input to produce visual assets like logos or posters, saving the output as PNG files.

What image aspect ratios and formats can I specify for AI image generation?

AI image generation supports multiple aspect ratios including 1:1, 16:9, 9:16, 4:3, and 3:4. The generated visual assets are outputted as PNG files, which are saved to a specified path on your system.

Do I need an API key to create AI art and graphics?

Yes, you need a valid Gemini API key to create AI art and graphics. You must configure either the GOOGLE_API_KEY or GEMINI_API_KEY environment variable to authenticate requests and generate visual assets successfully.

Can I use presets to quickly generate logos and icons?

Yes, you can use built-in presets like fenrir-logo, fenrir-icon, norse-badge, and fenrir-medallion to quickly generate logos and icons. These presets allow for rapid visual concept creation without writing complex prompts.

What should I do if my text-to-image generation encounters an error?

If your text-to-image generation encounters an error, the tool handles it gracefully. Ensure your GOOGLE_API_KEY or GEMINI_API_KEY is valid and check that your specified output path is accessible to resolve common generation failures.

Can I generate multiple images from a single text prompt?

Yes, you can generate multiple images from a single text prompt. The image generation tool supports multiple-image output, allowing you to produce several PNG visual assets simultaneously based on your prompt and aspect ratio settings.
