multilingual image text layout: separate generated backgrounds from reviewed language layers
Multilingual image text layout works best when the background and the language layer have independent lifecycles. A scene can be reused across locales while each translation receives its own line breaks, font checks, and approval. Asking an image model to paint every language into the scene makes those corrections harder to control.
Genace provides image generation, not a multilingual typesetting or translation approval system. Generate a suitable background, then compose reviewed copy using your own renderer or editor. Preserve editable language layers until the final export passes review.
Prepare content by locale
Collect approved headline, supporting copy, action text, and any required short labels for each locale. Include language direction and a reviewer who can read the actual wording. Do not estimate layout from an English placeholder when another version may need more space.
Identify text that must remain as live interface text rather than being embedded in a raster image. A promotional background can often stay text-free while the surrounding page supplies accessible, selectable wording.
Create a layout test matrix
| Test | What to inspect | Failure signal |
|---|---|---|
| Font coverage | Every intended character renders | Missing glyph boxes |
| Line breaks | Meaning remains readable | Isolated word or awkward wrap |
| Direction | Alignment and ordering match content | Mixed-direction fragments misplaced |
| Length | All approved copy fits | Clipping or shrinking below readable size |
| Export | Final raster matches preview | Different font or crop |
When using web fonts, review the font loading configuration and fallback behavior described in MDN’s font-face reference. Wait for the intended fonts before capturing a raster export.
Make room before polishing
Reserve a text region large enough for the longest approved version. If one language still fails, adjust its layout deliberately rather than squeezing every locale into identical line breaks. Shared visual identity does not require identical text geometry.
Keep the background’s important subject outside the text region. A generation brief can request empty space, but you still need to verify the selected candidate. If there is no workable region, choose another candidate or crop instead of covering important content.
Use a native-language reviewer to check the final rendered export, not just the translation document. Correct words can become confusing when punctuation, direction, or line breaks change their presentation.
Version each locale independently
Link every export to the common background source, locale content revision, font version, and layout recipe. A correction to one language should create a new derivative for that locale without overwriting every other approved file.
Avoid placing locale names only in folder paths. Keep them in the asset manifest and publishing mapping too, especially when the destination service renames uploaded files.
Acceptance checklist
Inspect every locale at actual display size, verify glyphs and direction, compare wording with the approved source, and check the destination crop. Confirm that no fallback-font capture slipped into delivery and that every language has its own review result.
