(I’m mostly working with the Java library iText, not with the .Net library iTextSharp; thus, please ignore some Java-isms here, everything should be easy to translate.) For extracting contents of a page using iText(Sharp), you employ the classes in the parser package to feed it after some preprocessing to a RenderListener of your choice. In … Read more
Yes there is. Check out the text.pdf.parser package, specifically LocationTextExtractionStrategy. Actually, that might not do the trick either. You’ll probably want to write your own TextExtractionStrategy to feed into PdfTextExtractor: MyTexExStrat strat = new MyTexExStrat(); PdfTextExtractor.getTextFromPage(reader, pageNum, strat); // get the strings-n-rects from strat. public class MyTexExStrat implements TextExtractionStrategy { void beginTextBlock() {} void endTextBlock() … Read more
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
This is one of those “sounds easy but is actually really complicated” things. See Mark’s posts here and here. Ultimately you’ll probably be pointed to LocationTextExtractionStrategy. Good luck! If you actually find out how to do it post it here, there several people wondering exactly what you are wondering!
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
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
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
