How can I set an A4 document in landscape (horizontal) format in iTextSharp? You can set the page size to a rotated A4. E.g. (assuming PDF, but should apply regardless): iTextSharp.text.Document doc; // ...initialize 'doc'... // Set the page size doc.SetPageSize(iTextSharp.text.PageSize.A4.Rotate()); I've done this with PDF without trouble, haven't tried it with other doc types. Alexei Bondarev You can initialize a new document like that: Document doc = new Document(iTextSharp.text.PageSize.A4.Rotate(), 10, 10, 10, 10); In this mode all pages will be in landscape mode.

Itextsharp text extraction

I'm using itextsharp on vb.net to get the text content from a pdf file. The solution works fine for some files but not for other even quite simple ones. The problem is that the token stringvalue is set to null (a set of empty square boxes) token = New iTextSharp.text.pdf.PRTokeniser(pageBytes) While token.NextToken() tknType = token.TokenType() tknValue = token.StringValue I can meassure the length of the content but I cannot get the actual string content. I realized that this happens depending on the font of the pdf. If I create a pdf using either Acrobat or PdfCreator with Courier (that by

Print PDF Created using itextsharp

问题 My Goal is to print a RDLC report on the client machine without preview. I can not use the ReportViewer print button since it requires the installation of ActiveX object and there are no permissions for that. So, I'm using ITextSharp to create a PDF from the byte array returned from the rendered LocalReport, and add a JavaScript for print. During Debug, I can see that the PDF is generated and has 2 pages, and everything looks OK. I don't receive any errors and the function exits OK, but it

I'd like that the text closed in .. has to be underlined. How could I do that? How could I approch it with HTMLWorker for example? Here's the portion of code where I write my description: for (int i = 0; i < linesDescription.Count; i++) { int count = linesDescription[i].Count(); int countTrim = linesDescription[i].Trim().Count();
