Let me give you a couple of things that might help you and then I’ll give you a full working example that you should be able to customize. The first thing is that the PdfPTable has a special method called WriteSelectedRows() that allows you to draw a table at an exact x,y coordinate. It has … Read more
You shouldn’t “guess” for the possible values. You need to use a value that is stored in the PDF. Try the CheckBoxValues example to find these possible values: public String getCheckboxValue(String src, String name) throws IOException { PdfReader reader = new PdfReader(SRC); AcroFields fields = reader.getAcroFields(); // CP_1 is the name of a check box … Read more
We need to write our own ImageTagProcessor to support processing of base 64 images: public class CustomImageTagProcessor : iTextSharp.tool.xml.html.Image { public override IList<IElement> End(IWorkerContext ctx, Tag tag, IList<IElement> currentContent) { IDictionary<string, string> attributes = tag.Attributes; string src; if (!attributes.TryGetValue(HTML.Attribute.SRC, out src)) return new List<IElement>(1); if (string.IsNullOrEmpty(src)) return new List<IElement>(1); if (src.StartsWith(“data:image/”, StringComparison.InvariantCultureIgnoreCase)) { // data:[<MIME-type>][;charset=<encoding>][;base64],<data> … Read more
I’m the original developer of iText, and the problem you’re experiencing is explained in my book. You’re mixing text mode and composite mode. In text mode, you create the PdfPCell with a Phrase as the parameter of the constructor, and you define the alignment at the level of the cell. However, you’re working in composite … Read more
Switch the filestream with a memorystream. MemoryStream memStream = new MemoryStream(); PdfWriter wri = PdfWriter.GetInstance(doc, memStream); … return memStream.ToArray();
As already answered by @Bruno you need to use pageEvents. Please check out the sample code below: private void CreatePDF() { string fileName = string.Empty; DateTime fileCreationDatetime = DateTime.Now; fileName = string.Format(“{0}.pdf”, fileCreationDatetime.ToString(@”yyyyMMdd”) + “_” + fileCreationDatetime.ToString(@”HHmmss”)); string pdfPath = Server.MapPath(@”~\PDFs\”) + fileName; using (FileStream msReport = new FileStream(pdfPath, FileMode.Create)) { //step 1 using (Document … Read more
Have you tried: PdfWriter writer = PdfWriter.GetInstance(doc, memoryStream); // Build pdf code… writer.CloseStream = false; doc.Close(); // Build email memoryStream.Position = 0; mm.Attachments.Add(new Attachment(memoryStream, “test.pdf”)); If my memory serves me correctly, this solved a similar problem in a previous project. See http://forums.asp.net/t/1093198.aspx
The problem is this line: Response.OutputStream.Write(MS.GetBuffer(), 0, MS.GetBuffer().Length) The GetBuffer method returns the entire internal buffer which is larger that the actual content. The bad PDF has about 10kb of garbage content at the end (bytes of zero), the good PDF has only a few garbage bytes. Use the ToArray() method of the memory stream … Read more
This one is a little complicated if you don’t know the internals of the PDF format and iText/iTextSharp’s abstraction/implementation of it. You need to understand how to use PdfDictionary objects and look things up by their PdfName key. Once you get that you can read through the official PDF spec and poke around a document … Read more
If you want to merge source documents using iText(Sharp), there are two basic situations: You really want to merge the documents, acquiring the pages in their original format, transfering as much of their content and their interactive annotations as possible. In this case you should use a solution based on a member of the Pdf*Copy* … Read more
