Preview and export the picture book

Review the sequence as a reader before exporting. One attractive image does not guarantee a good chapter; movement, character appearance, color, and information density must work across adjacent frames.

Preview the chapter continuously

1. Open the chapter’s Comic workspace and enter continuous preview.
2. Inspect the current image of every active section in order.
3. Look for sudden costume changes, time-of-day jumps, contradictory movement, or repetitive framing.
4. Return to the relevant section to change its storyboard, references, or current candidate, then preview again.

Preview uses the current image of each active section. A generated candidate does not replace the current frame until you make it current.

Understand export readiness

Lumi checks the current snapshot before creating an export:

• Every active section has a ready image: create a complete export directly.
• Some active sections have no image: the dialog shows how many are missing; create a partial export only after explicitly allowing missing images.
• No image is available: export is blocked until at least one current frame is ready.

Export one chapter

1. Open the export dialog from the current chapter.
2. Choose “Original-image ZIP” or “A4 PDF.” Lumi does not preselect a format.
3. If images are missing, return to complete them or explicitly confirm an export containing only the available images.
4. Create the task and wait for progress to complete. You may cancel it while active; retry the original task after failure or cancellation where the dialog offers that control.
5. Download the completed file in its selected format. Lumi does not automatically start a download when the task finishes.

How Lumi lays out an A4 PDF

The PDF is always A4 portrait. Page 1 is a text cover: a project export shows the project name, while a chapter export also shows the chapter code and title. Remaining pages follow the picture-book ratio frozen when the project was created:

• Landscape and interactive picture books place two images vertically on each page.
• Vertical strips place two tall images side by side on each page.
• Square and other portrait picture books place one image on each page.

Every image is centered in full without cropping, rotation, or stretching. A project PDF never combines images from two chapters on one page; every chapter starts on a new page. GIF exports use the first frame.

Export the whole project

Create a project-scoped export from Overview → Exports. It includes active chapters and frames that satisfy the current snapshot. Check readiness for each chapter before allowing any missing images.

Export history is paginated and saved by the service. Download a completed historical item directly instead of regenerating the same snapshot.

Check the downloaded result

Extract a ZIP into a new folder and verify filenames, image count, reading order, and that every image opens correctly. For a PDF, verify the cover, page count, chapter breaks, and that every image remains complete. Do not extract a ZIP inside your only project folder, where delivery files could be confused with project assets.
