Page proofreading method and apparatus

摘要

The present invention discloses a method and apparatus for page proofreading, the method comprising: splitting a document before modification to at least one single page document file before modification and splitting a document after modification to at least one single page document file after modification; adding the at least one single page document before modification into a first page, adding the at least one single page document after modification into a second page; setting correlativity between each of the single page documents before modification in the first page and each of the single page documents after modification in the second page; comparing pixel elements of the previews of the single page document before modification and the single page document after modification for all of the first pages and the second pages that correlated with each other; if there are different parts, displaying the comparison result by marking the different parts.
