Can iTextSharp Convert PDF to PDF / A

Question

I can’t find in the FAQ if this functionality exists in the API, although it is mentioned in the book as potentially available. Has anyone had experience implementing this feature?

Answer 1

On This thread (June 2007) Paulo Soares provides code that shows support for PDF / A. Here's the C # code (it also has a Java sample):

private void PdfATest() { Document doc = new Document(PageSize.A4); PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream("C:\\hello_A1-b_cs.pdf", FileMode.Create)); writer.PDFXConformance = PdfWriter.PDFA1B; doc.Open(); PdfDictionary outi = new PdfDictionary(PdfName.OUTPUTINTENT); outi.Put(PdfName.OUTPUTCONDITIONIDENTIFIER, new PdfString("sRGB IEC61966-2.1")); outi.Put(PdfName.INFO, new PdfString("sRGB IEC61966-2.1")); outi.Put(PdfName.S, PdfName.GTS_PDFA1); // get this file here: http://old.nabble.com/attachment/10971467/0/srgb.profile ICC_Profile icc = ICC_Profile.GetInstance("c:\\srgb.profile"); PdfICCBased ib = new PdfICCBased(icc); ib.Remove(PdfName.ALTERNATE); outi.Put(PdfName.DESTOUTPUTPROFILE, writer.AddToBody(ib).IndirectReference); writer.ExtraCatalog.Put(PdfName.OUTPUTINTENTS, new PdfArray(outi)); BaseFont bf = BaseFont.CreateFont("c:\\windows\\fonts\\arial.ttf", BaseFont.WINANSI, true); Font f = new iTextSharp.text.Font(bf, 12); doc.Add(new Paragraph("hello", f)); writer.CreateXmpMetadata(); doc.Close(); } 

The link above contains the download of the ICC_Profile file.

Here's my method for parsing an HTML file and creating a PDF / A document from it, and also for embedding fonts using a stylesheet (to avoid the error: "All fonts must be embedded. T: Helvetica")

Hope this helps someone.

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using iTextSharp.text.pdf; using iTextSharp.text; using System.IO; using iTextSharp.text.html.simpleparser; namespace SaveAsPDF { class HtmlPdfConverter { public void RendererWebForm2PDFArchive(string fileName) { Console.WriteLine("Parsing HTML " + fileName); Document document = new Document(PageSize.A4); try { // we create a writer that listens to the document and directs a XML-stream to a file PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(fileName + ".pdf", FileMode.Create)); //set document as arhive writer.PDFXConformance = PdfWriter.PDFA1A; document.Open(); //apply stylesheet to change font (and embedd it) StyleSheet styles = new StyleSheet(); FontFactory.Register("c:\\windows\\fonts\\verdana.ttf"); styles.LoadTagStyle("body", "face", "Verdana"); //prepare html StreamReader sr = new StreamReader(fileName, Encoding.Default); string html = sr.ReadToEnd(); html = RemoveTag(html, "<title>", "</title>"); //convert string to stream byte[] byteArray = Encoding.UTF8.GetBytes(html); MemoryStream ms = new MemoryStream(byteArray); //parse html HTMLWorker htmlWorker = new HTMLWorker(document); System.Collections.Generic.List<IElement> elements; elements = HTMLWorker.ParseToList(new StreamReader(ms), styles); foreach (IElement item in elements) { document.Add(item); } writer.CreateXmpMetadata(); document.Close(); Console.WriteLine("Done"); } catch (Exception e) { Console.Error.WriteLine(e.Message); Console.Error.WriteLine(e.StackTrace); } }**strong text**
