Tools

The Tools category in the left panel gathers page-level utilities.

Clean

Clean lifts a scanned page’s background — coffee stains, shadows, photocopier grey — while preserving the printed text:

1. Tap Clean. Lx1go analyses the page (using the indexed text as a mask) and shows a live preview.
2. Drag the aggressiveness slider until the page looks right — gentle keeps faint pencil marks, aggressive whitens hard.
3. Confirm to save the cleaned image, or cancel to keep the original.

The original image is backed up automatically the first time you clean a page.

Revert

Restores the page’s original imported image, undoing any Clean. Available whenever a backup of the original exists.

Clear Page

Removes every element and drawing from the current page (the page image stays). This goes through the undo stack, so a mistaken clear is one Undo away.

Zoom Save / Zoom Restore

Pins the current zoom and pan to this specific page — see Navigation & Zoom. Zoom Restore re-applies the pinned view, or resets to 100% if none is saved.

Styles

A shortcut to the show’s Styles screen.
