I have a number of Dynamic XFA PDFs that were created with Livecycle Designer. These PDFs are used as templates for various individuals to complete. When a user requests a template we have to write a submit button with url pointing back to a .net application for processing and update some of the fields with information from the database into the PDF.
Can I use iText(Sharp) with .net to update the dynamic xfa pdf to write into it a submit button and update fields and then use iText(Sharp) to process the returning form.
We are doing this now with Acroforms but need to do the same for Dynamic XFA forms as well. I can’t find any confirmation information that this is possible. If it is possible does anyone have any code that they can share to show me how to do this?
You can also achieve that putting the pdf's content inside an XmlDocument and working as you were working with an XML.
This is the code I use to replace some placeholders written in textboxes.
PdfReader pdfReader = new PdfReader(path_pdf);
using (PdfStamper pdfStamp = new PdfStamper(pdfReader, new FileStream(temp_path, FileMode.Create), '\0', true))
{
pdfStamp.ViewerPreferences = PdfWriter.AllowModifyContents;
XmlDocument xmlDocument = pdfReader.AcroFields.Xfa.DomDocument;
string pdfContent = xmlDocument.InnerXml;
string newpdfContent = pdfContent
.Replace("$CONTENT_TO_REPLACE_1$", "some_content")
.Replace("$CONTENT_TO_REPLACE_2$", "some_other_content")
xmlDocument.InnerXml = newpdfContent;
Stream stream = GenerateStreamFromString(newpdfContent);
pdfStamp.AcroFields.Xfa.FillXfaForm(stream);
pdfStamp.AcroFields.Xfa.DomDocument = xmlDocument;
pdfStamp.Close();
}

I am using grails 2.5.2.
I have created a table which shows all the data from database to gsp page and now i need to save that shown data in a pdf format with a button click.What will be the best way to show them into a PDF and save it to my directory. please Help
You can use itext for converting HTML into pdf using the code below:
public void createPdf(HttpServletResponse response, String args, String css, String pdfTitle) {
response.setContentType("application/force-download")
response.setHeader("Content-Disposition", "attachment;filename=${pdfTitle}.pdf")
Document document = new Document()
Rectangle one = new Rectangle(900, 600)
document.setPageSize(one)
PdfWriter writer = PdfWriter.getInstance(document, response.getOutputStream())
document.open()
ByteArrayInputStream bis = new ByteArrayInputStream(args.toString().getBytes())
ByteArrayInputStream cis = new ByteArrayInputStream(css.toString().getBytes())
XMLWorkerHelper.getInstance().parseXHtml(writer, document, bis, cis)
document.close()
}
Though answering this question late,take a look at grails export plugin.It will be useful if you want to export your data to excel and pdf( useful only if there is no in pre-defined template to export).
Got idea from itext. Used itext 2.1.7 and posted all the values to pdf from a controller method. Used images as background and paragraph and phrase to show values from database.
I'm working to refactor a PDF form web application that is using the Active PDF Toolkit and the FDFToolkit from Adobe. My goal is to use iTextSharp to:
Pre-populate the form fields with data from the database
Allow the user to attach a signature and/or barcode image via FDF
Item #1 is not the problem. Item #2 is the biggest challenge. Let me provide some background:
This is a web application which renders the PDF form once. After the initial load, there are 2 key buttons on the form which submit the PDF form to a URL with an action parameter in the query string. These buttons are called "Save" and "Sign". The Save button takes the FDF field dictionary and saves it to the database. The Sign button looks up the signature for the logged-in user and attaches the signature image to the FDF and writes the FDF to the HTTP Response.
The FDFToolkit supports attaching an image to a field using this method:
FDFSetAP(string bstrFieldName, short whichFace, string bstrFileName, short pageNum)
iTextSharp does not offer a comparable method in the FdfWriter class. I've considered subclassing the FdfWriter class and adding my own method to attach an image, but wanted to reach out here to see if anyone has had the same problem.
I have been able to overlay an image on top of a field using this method, but this is in the underlying PDF and not the FDF.
AcroFields.FieldPosition pos = _Stamper.AcroFields.GetFieldPositions("SIGNATUREFIELD").First();
Image signature = Image.GetInstance("Signature.gif");
image.SetAbsolutePosition(pos.position.Left, pos.position.Bottom);
image.ScaleToFit(pos.position.Width, pos.position.Height);
PdfContentByte pcb = _Stamper.GetOverContent(pos.page);
pcb.AddImage(image);
Thanks!
I've put images on forms by using the PdfStamper and making Pushbutton fields. You can replace your existing field with a Pushbutton field and set the Pushbutton to READ_ONLY so that it can't be pressed and it will look like a static image. This will keep the image you're trying to add as a field annotation instead of adding it to the page content.
using (PdfStamper stamper = new PdfStamper(new PdfReader(inputFile), File.Create(outputFile)))
{
AcroFields.FieldPosition fieldPosition = stamper.AcroFields.GetFieldPositions(fieldName)[0];
PushbuttonField imageField = new PushbuttonField(stamper.Writer, fieldPosition.position, fieldName);
imageField.Layout = PushbuttonField.LAYOUT_ICON_ONLY;
imageField.Image = iTextSharp.text.Image.GetInstance(imageFile);
imageField.ScaleIcon = PushbuttonField.SCALE_ICON_ALWAYS;
imageField.ProportionalIcon = false;
imageField.Options = BaseField.READ_ONLY;
stamper.AcroFields.RemoveField(fieldName);
stamper.AddAnnotation(imageField.Field, fieldPosition.page);
}
I am trying to automate printing of intranet websites. Since this is an application that will be put on a specific user's computer, which will be run on an as-needed basis, I'd like it to be as un-disruptive as possible (in other words, not launching IE for each page). The catch is that I need to print the first page of the website and then print the whole website again, which will produce the first page two times. What is the best way to do this?
I have no problem getting it to loop through the pages that it needs to print, nor do I have a problem opening the page with webbrowser. I do, however, have a problem specifying a print range.
I also tried PrintDocument, but couldn't figure out how to get that to open within the form.
Thanks for any help that can be provided.
To download the pdf file, try this solution using iTextSharp:
ITextSharp HTML to PDF?
Except with one substitution if you want to save directly to a file
private MemoryStream createPDF(string html)
{
MemoryStream msOutput = new MemoryStream();
TextReader reader = new StringReader(html);
// step 1: creation of a document-object
Document document = new Document(PageSize.A4, 30, 30, 30, 30);
// step 2:
// we create a writer that listens to the document
// and directs a XML-stream to a file
PdfWriter writer = PdfWriter.GetInstance(document, new FileStream("c:\\my.pdf", FileMode.Create));
// step 3: we create a worker parse the document
HTMLWorker worker = new HTMLWorker(document);
// step 4: we open document and start the worker on the document
document.Open();
worker.StartDocument();
// step 5: parse the html into the document
worker.Parse(reader);
// step 6: close the document and the worker
worker.EndDocument();
worker.Close();
document.Close();
return msOutput;
}
Once the PDF is set up, try ghostscript to print one page:
Print existing PDF (or other files) in C#
If you start a shell execute of the process, you can use the command line arguments:
gsprint "filename.pdf" -from 1 - to 1
Alternatively, WebBrowser can just print the full page: http://msdn.microsoft.com/en-us/library/b0wes9a3.aspx
I can't find anything referencing that WebBrowser itself can print "From page X to Y" without a print dialog.
Since I'm facing a similar problem, here's an alternate solution:
This open source project turns HTML documents to PDF documents similar to iTextSharp (http://code.google.com/p/wkhtmltopdf/). We ended up not using iTextSharp because of several formatting issues with the way the site we wanted to print was laid out. We send command line arguments to turn the html downloaded using a webclient into a pdf file.
WebClient wc = new WebClient();
wc.Credentials = CredentialCache.DefaultNetworkCredentials;
string htmlText = wc.DownloadString("http://websitehere.com);
Then, after turning to pdf, you can simply print the file:
Process p = new Process();
p.StartInfo.FileName = string.Format("{0}.pdf", fileLocation);
p.StartInfo.Verb = "Print";
p.Start();
p.WaitForExit();
(Apologies for C#, I'm more familiar with it than VB.NET, though it should be a simple conversion)
I am trying to convert a web form to a pdf after a user fills in the fields in the web form. Is this possible? All i can do right now is loop through the form collection and print out the field name and the field value to the pdf. Is there a way to do this and keep the pdf looking like the web form?
I'm using mvc 3 for the web page.
Thanks!
Now I am using the following which converts everything in the form but the form fields.
Document doc = new Document();
String path = "C:\\projects\\pdfs\\";
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(path + "Doc1.pdf", FileMode.Create));
StringReader sr = new StringReader(htmlString);
HTMLWorker worker = new HTMLWorker(doc);
doc.Open();
worker.Parse(sr);
doc.Close();
How do I get the form fields to display in the pdf?
string pdfTemplate = #"Trust App form.pdf";
string newFile = #"Trust App form Completed.pdf";
PdfReader pdfReader = new PdfReader(pdfTemplate);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(
newFile, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
pdfFormFields.SetField("trust.trustee.entityname.line1", "Gulistan-e-Jauhar Karachi");
pdfStamper.FormFlattening = false;
pdfStamper.Close();
I am able to fill pdf forms using Itext sharp pdf.
But problem is this pdf is for .net. I WANT TO USE IT IN SILVERLIGHT.
Is there any alternative? for filling pdf form in silverlight... what i think itext sharp give silverpdf (http://silverpdf.codeplex.com/) but there is pdfstamper and acrofields classes in silverpdf.
SilverPDF looks to be inspired/based-on iTextSharp and PDFSharp, but it doesn't use an identical class layout by any means.
I just poked around in their code a bit (they have no docs that I could find), and it looks like you need to get the field's PdfAcroField object from the PdfAcroForm, which you get from a PdfDocument, which in turn you get from PdfReader.open(...).
When the docs aren't good enough, check the code if at all possible.
