Remarks
On adding pages, checks that the new page is not attached to any other document. The Remove method detaches a page from the document. If it is referenced from anywhere else, it remains a valid stand-alone page.
Well-formed page array may contain any number of null entries. An exception is made for the formats where pages are physically continuous (i.e., PDF). Note that setting a page to null is different from removing a page from the document - the former does not change page count, whereas the latter does.

int pageCount; ImGearDocument igDocument; using (FileStream localFile = new FileStream(localFilePath, FileMode.Open)) { pageCount = ImGearFileFormats.GetPageCount(localFile, ImGearFormats.UNKNOWN); igDocument = ImGearFileFormats.LoadDocument(localFile, 0, pageCount); } //Check pages swap possibility if (pageCount > 1) { ImGearPage igPage = igDocument.Pages[0]; igDocument.Pages.Remove(igPage); igDocument.Pages.Insert(1, igPage); } | |
