i'm currently using the following but it has not effect..
Code:
//Open input document
PdfDocument InputPDFDoc = PdfReader.Open(file, PdfDocumentOpenMode.Import);
//iterate through pages
int count = InputPDFDoc.PageCount;
for (int i = 0; i < count; i++)
{
//Get page from input
PdfPage CurrentPage = new PdfPage();
CurrentPage = InputPDFDoc.Pages[i];
//...and add it to the output
OutputPDFDoc.AddPage(CurrentPage);
XGraphics gfx = XGraphics.FromPdfPage(OutputPDFDoc.Pages[OutputPDFDoc.Pages.Count -1]);
gfx.Transform.TranslateAppend(100, 0);
}
