ClonePages Method (GdPicturePDF)

In This Topic

Clones a range of pages located in the specified source PDF document into the currently loaded PDF document. The new pages are added at the end of the current document and the last page 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.

This method is a alternative to GdPicturePDF.ClonePage method in cases where multiple pages need to be cloned together.
