Export Pages and Manage Projects

Koharu's workflow is page-based. You import image pages, run the pipeline, review text blocks, and then export either flattened output or a layered handoff file for manual finishing.

Supported page inputs

The current import flow is image-based. Koharu accepts:

  • .png
  • .jpg
  • .jpeg
  • .webp

Folder import recursively scans for supported image files and ignores everything else.

Export rendered output

Koharu can export the current page as a rendered image.

Use this when you want a final flattened result for reading, sharing, or publishing.

Implementation details:

  • rendered export uses the page's original image extension when possible
  • Koharu names the exported file with a _koharu suffix
  • rendered export requires the page to already have a rendered layer

Example output names:

  • page-001_koharu.png
  • chapter-03_koharu.jpg

Export inpainted output

Koharu also keeps an inpainted layer in the pipeline, which is useful when you want a cleaned page without translated lettering.

This is most useful for:

  • external lettering workflows
  • cleanup review
  • batch export of text-removed pages

When exported, Koharu uses an _inpainted filename suffix.

Export layered PSD files

Koharu can also export a layered Photoshop PSD.

PSD export is the handoff format for users who want to keep working in Photoshop or a PSD-compatible editor after the ML pipeline is done.

In the current implementation, PSD export uses editable text layers by default and can include:

  • the original image
  • the inpainted image
  • the segmentation mask
  • the brush layer
  • translated text layers
  • a merged composite image

That makes the PSD much more useful than a flat image when you still need to:

  • tweak wording
  • adjust bubble fit
  • repaint artifacts
  • hide or inspect helper layers

Koharu names PSD exports with a _koharu.psd suffix.

PSD export limitations

Koharu currently writes classic PSD files, not PSB files. That means very large pages can fail to export.

The implementation rejects dimensions above 30000 x 30000.

Manage loaded page sets

Koharu lets you work with multiple loaded pages in one session.

The practical choices are:

  • open images and replace the current set
  • append more images to the current set
  • open a folder and load its supported image files
  • append a folder to the current set

This is the main way to manage a chapter or batch job inside the app today.

When to use each format

Output Best for
Rendered image final delivery, reading copies, simple sharing
Inpainted image external lettering, cleanup review, text-removal workflows
PSD manual cleanup, touch-up, editable translated text

If you care about polish, a good pattern is:

  1. run detection, OCR, translation, and render in Koharu
  2. export a rendered image for quick review
  3. export a PSD when you want editable text and helper layers for final cleanup
