FAQ
How does the curve near the spine get fixed?
Book mode flattens the curve automatically when it splits the spread. If the app cannot detect the page edges clearly, it keeps the image as-is rather than distorting it.
How many pages can I scan in one session?
Up to 50 pages per session. Each captured page is kept at roughly 2400 pixels on its long side.
Can I undo the two-page split after capturing?
Yes. After the spread is split, an undo strip appears so you can merge the two halves back into a single image.
