I have a PDF template created in LibreOffice and I'm filling it in using AcroFields. In some rare cases I'd like to hide a particular field, thus I remove it using RemoveField method. It's border however stays in there. From what I've googled it seems it's probably the way LibreOffice creates the forms. What I've came up with so far was to get the rectangle of the field and cover it with white image. Problem however is, customer plans creating templates using background image and/or other background color than white making my current solution almost unusable The question therefore is - is

I would like to add a link to an existing pdf that jumps to a coordinate on another page. I am able to add a rectangle using this code: PdfContentByte overContent = stamper.GetOverContent(1); iTextSharp.text.Rectangle rectangle = new Rectangle(10,10,100,100,0); rectangle.BackgroundColor = BaseColor.BLUE; overContent.Rectangle(rectangle); stamper.Close(); How can I do similar to create a link that is clickable? Thanks. This is explained in chapter 7 of the book "iText in Action - Second Edition" . You can find an example here: http://itextpdf.com/examples/iia.php?id=150 If you need the C#

I am using iTextSharp and trying to extract images with transparency from a PDF. When I extract the image the transparency becomes solid black and is lost. I have found multiple examples of image extraction but all of them seem to have the same issue. The code that I am using is below Another example is from itextpdf.com/examples/iia.php?id=284. This example includes images in the "results" section at the top. If you click Img7.png you will see the black border in the image, however at the bottom of the page there is a link to the original image info.png that shows the transparency the way it

I have underlined "Some text" by var par = new Paragraph(); par.Add(new Chunk("Some text", CreateFont(12, Font.UNDERLINE))); document.Add(par); It is possible underline just "Some text" with dashed line (not the paragraph)? Thanks Chris Haas This answer tells you how to do it but unfortunately doesn't provide any code so I've provided it below. To the best on my knowledge there isn't a direct way to achieve this in iTextSharp by just setting a simple property. Instead, you need to use a PageEvent and manually draw the line yourself. First you need to subclass PdfPageEventHelper : private class

I'm trying to create a pdf document using iTextSharp 5.3.4 using the following Document document = new Document(); FileStream stm = new FileStream(filename, FileMode.Create); PdfWriter writer = PdfWriter.GetInstance(document, stm); I'm getting a System.NullReferenceException with the following stack trace: System.NullReferenceException occurred HResult=-2147467261 Message=La référence d'objet n'est pas définie à une instance d'un objet. Source=itextsharp StackTrace: à iTextSharp.text.Version.GetInstance() InnerException: I've verified that neither document nor stm are null, and if I select

i tryed both, but still not working iTextSharp + FileStream = Corrupt PDF file iTextSharp is producing a corrupt PDF using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream()) { //abre o documento para poder editar document.Open(); //Adiciona os campos de assinatura document.Add(Assinatura()); //fecha o documento ao finalizar a edição document.Close(); //Prepara o download byte[] bytes = memoryStream.ToArray(); memoryStream.Close(); Response.Clear(); Response.ContentType = "image/pdf"; //Response.ContentType = "application/pdf"; Response.AddHeader("Content-Disposition",

At my work sometimes I have to merge from few to few hundreds pdf files. All the time I've been using Writer and ImportedPages classes. But when I have merged all files into one, file size becomes enormous, sum of all merged files sizes, because fonts being attached to every page, and not reused (fonts are embedded to every page, not whole document). Not very long time ago I found out about PdfSmartCopy class, which reuses embedded fonts and images. And here the problem kicks in. Very often, before merging files together, I have to add additional content to them (images, text). For this

I am trying to get a simple list of all the fields in my XFA form. I am using this code: private void ListFieldNames() { string pdfTemplate = @"C:\Projects\iTextSharp\SReport.pdf"; MemoryStream m = new MemoryStream(); // title the form this.Text += " - " + pdfTemplate; // create a new PDF reader based on the PDF template document PdfReader pdfReader = new PdfReader(pdfTemplate); PdfStamper pdfStamper = new PdfStamper(pdfReader, m); AcroFields formFields = pdfStamper.AcroFields; AcroFields form = pdfReader.AcroFields; XfaForm xfa = form.Xfa; StringBuilder sb = new StringBuilder(); sb.Append(xfa

Using iTextSharp , how can I merge multiple PDFs into one PDF without losing the Form Fields and their properties in each individual PDF? (I would prefer an example using streams from a database but file system is ok as well) I found this code that works but it flattens out my PDFs so I can't use it. UPDATE @Mark Storer - This is the code I am using now based on your feedback (see below) but it gives me a corrupt document after the save. I tested each of the code parts separately and it seems to be failing in the MergePdfForms function shown below. I obviously don't want to use the
