Regarding duplicate and blank pages in iOS sdk in Complate reader

1.Does sdk provide Blank page and duplicate page?

Yes, to add a blank


As for duplicating, there is no direct way, but the easiest would be the following.

Page duplicate = doc.PageCreate(source_page.GetCropBox());


Stamper stamper = new Stamper(Stamper.SizeType.e_relative_scale, 1.0, 1.0);
stamper.StampPage(doc, source_page, new PageSet(doc.GetPageCount()));
