ClonePage(Int32) Method

In This Topic
Clones a page specified by its page number, that means creates exactly the same copy of the specified page, in the currently loaded PDF document. The newly created page is added at the end of the document as the last page and it is automatically selected as the current page.

Just to inform you, that the toolkit offers the adaptive file caching mechanism to significantly reduce memory usage while cloning large documents. The feature is available in both 32-bit and 64-bit mode by default.
