I try to create a multipage pdf document using iTextSharp. I have a object that contains the orientation of itself (landscape or portrait). When The first Object contains informations that it needs landscape mode, i create the document with Document doc = new Document(PageSize.A4.Rotate(), 10f, 10f, 10f, 0f)
. This works pretty good until the next element is in portrait mode! If an element is in portrait mode, i set the pagesize again: doc.SetPageSize(PageSize.A4);
.
At this point the element should be on a portrait A4 page in the PDF document but it is still in landscape mode. It switches pages not until a new object is reached OR a pagebreak is reached within the current element!
Here is my code:
TableObject to_first = myTables.First();
//current object need landscape orientation
if (to_first._orientation == "landscape")
{
//Create an iTextSharp Document which is an abstraction of a PDF but **NOT** a PDF
using (Document doc = new Document(PageSize.A4.Rotate(), 10f, 10f, 10f, 0f))
{
//Create a writer that's bound to our PDF abstraction and our stream
using (PdfWriter writer = PdfWriter.GetInstance(doc, ms))
{
//Open the document for writing
doc.Open();
//writer.CloseStream = false;
//loop all tableobjects inside the document & the instance of PDFWriter itself!
foreach (TableObject to in myTables.ToList())
{
doc.NewPage();
//look for the requested orientation by the current object and apply it
if (to._orientation == "landscape")
{
doc.SetPageSize(PageSize.A4.Rotate());
}
else if (to._orientation == "portrait")
{
doc.SetPageSize(PageSize.A4);
}
currentTable = to;
//Get the data from database corresponding to the current tableobject and fill all the stuff we need!
DataTable dt = getDTFromID(currentTable._tableID);
Object[] genObjects = new Object[5];
genObjects = gen.generateTable(dt, currentTable._tableName, currentTable._tableID.ToString(), currentTable, true);
StringBuilder sb = (StringBuilder)genObjects[1];
String tableName = sb.ToString();
Table myGenTable = (Table)genObjects[0];
String table = genObjects[2].ToString();
using (StringReader srHtml = new StringReader(table))
{
//Parse the HTML
iTextSharp.tool.xml.XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, srHtml);
}
}
//After all of the PDF "stuff" above is done and closed but **before** we
//close the MemoryStream, grab all of the active bytes from the stream
doc.Close();
bytes = ms.ToArray();
}
}
}
How can I ensure that every page is rotated correctly?

doc.SetPageSize
only sets the size used for creating new pages, not for the existing pages. Thus, you should move your
doc.NewPage();
call after the SetPageSize
calls:
//look for the requested orientation by the current object and apply it
if (to._orientation == "landscape")
{
doc.SetPageSize(PageSize.A4.Rotate());
}
else if (to._orientation == "portrait")
{
doc.SetPageSize(PageSize.A4);
}
// After setting the page size, trigger the generation of the new page
doc.NewPage();
