Problem
Many platforms generate images dynamically (cover images, social previews, banners), but text inside these images is usually static and language-specific.
For multilingual products, this means:
- Creating and maintaining separate images per language
- Repeating design work for the same layout
- Increased storage and manual effort
There is no simple, reusable way to generate images where the embedded text adapts automatically to different languages.
Solution
Build a multi-language cover image generator that renders translated text directly inside images.
The idea is to generate images (SVG-first) where the same layout and styling are reused, but the text adapts based on a language parameter.
How should it work?
A simple image generation endpoint accepts text and a language code.
Example:
/api/cover?text=Build%20Fast&subtitle=Cover%20Image&lang=hi
Flow:
- Input text is translated based on the requested language
- The translated text is rendered directly inside an SVG
- The generated image is returned as a response
This approach avoids storing multiple image assets and keeps everything dynamic.
Visuals
Example output:
- A cover image with a fixed layout and theme
- Title and subtitle rendered in the selected language
- Same image template reused across languages
Workarounds
As a proof of concept, I built a small Express-based SVG image generator that:
- Accepts text and language as query parameters
- Generates cover images dynamically
- Demonstrates how multi-language text can be embedded in images
This validates the idea, but the goal of the community project is to formalize and document this approach so others can reuse it.
