Deskew the scanned page content

Question: Why does [Automatic] deskew not deskew the page?

Answer:

1. The page cannot be deskewed automatically when the deskew angle is greater than 20

degrees. First do a manual deskew and then an automatic deskew.

2. There is too little information or too many graphics on the page to deskew automatically.

Deskew manually.

3. Due to the skew algorithm, texts that use non-Latin fonts (e.g. Chinese and Japanese) do not

deskew automatically. Deskew manually.

Question: Why is content lost after a deskew at a large angle?

Answer: The content is rotated during the deskew. Content that is rotated beyond the page

boundaries is lost permanently. Click [Undo] to recover the lost content.
