Hi Bruno,
I've followed your comments and I imported 1 page of an A4 landscape PDF and
created 1 A5 portrait vertically splitted of A4. The C# code:
// source.pdf is A4 Landscape format
PdfReader reader = new PdfReader("source.pdf");
int n = reader.NumberOfPages;
iTextSharp.text.Rectangle psize =
reader.GetPageSize(1);
float width = psize.Width;
float height = psize.Height;
Document document = new Document(PageSize.A5);
// target.pdf is A5 Portrait format
PdfWriter writer =
PdfWriter.GetInstance(document, new
FileStream("target.pdf", FileMode.Create));
document.Open();
PdfContentByte cb = writer.DirectContent;
document.NewPage();
PdfImportedPage page1 =
writer.GetImportedPage(reader, 1);
cb.AddTemplate(page1, 1, 0, 0, 1, 0, 0);
// page1 created - an half of source A4
landscape page
--->Here follows the problem: I want to add second page of source and I
don't know how to setup the offset:
document.NewPage();
cb.AddTemplate(page1, A, B, C, D, E, F);
document.Close();
I'm a bit lost in the transformation matrix... Please, could you tell mi how
to setup the A,B,C,D,E and F values?
Thanks,
Pavol.
