I have the following code to set background color to one of my fields but for some reason I can not control the transparency of the background. Can someone please take a look at it and let me know what I am doing wrong. Thanks.
using (var newFileStream = new FileStream(fileNameNew, FileMode.Create))
{
// Open existing PDF
var pdfReader = new PdfReader(existingFileStream);
// PdfStamper, which will create
var stamper = new PdfStamper(pdfReader, newFileStream);
var form = stamper.AcroFields;
var fieldKeys = form.Fields.Keys;
foreach (string fieldKey in fieldKeys)
{
if (fieldKey.Equals("Title"))
{
form.SetFieldProperty(fieldKey, "bgcolor", new BaseColor(System.Drawing.Color.FromArgb(20,225,160,0)),null);
form.SetField(fieldKey, "Test");
}
else
{
form.SetField(fieldKey, "REPLACED!");
}
}
stamper.FormFlattening = true;
stamper.Close();
pdfReader.Close();
}
Just in case anyone else faces the same problem
var pdfReader = new PdfReader(existingFileStream);
// PdfStamper, which will create
var stamper = new PdfStamper(pdfReader, newFileStream);
var form = stamper.AcroFields;
var fieldKeys = form.Fields.Keys;
PdfContentByte background;
foreach (string fieldKey in fieldKeys)
{
if (fieldKey.Equals("Title"))
{
//form.SetFieldProperty(fieldKey, "bgColor", new BaseColor(System.Drawing.Color.FromArgb(125,225,160,0)),null);
form.SetField(fieldKey, "Test");
IList<AcroFields.FieldPosition> pos = form.GetFieldPositions(fieldKey);
PdfContentByte contentBtye = stamper.GetOverContent(pos[0].page);
contentBtye.SetColorFill(new BaseColor(200, 50, 50));
contentBtye.Rectangle(pos.FirstOrDefault().position.Left, pos.FirstOrDefault().position.Bottom, pos.FirstOrDefault().position.Width, pos.FirstOrDefault().position.Height);
PdfGState state = new PdfGState();
state.FillOpacity = 0.5f;
contentBtye.SetGState(state);
contentBtye.Fill();
}
else
{
form.SetField(fieldKey, "REPLACED!");
}
}

I have an XFA form that I can successfully fill in by extracting the XML modifying and writing back. Works great if you have the full Adobe Acrobat, but fails with Adobe Reader. I have seen various questions on the same thing with answers but they were some time ago so updating an XFA that is readable by Adobe Reader may no longer be doable?
I use this code below and I've utilised the StampingProperties of append as in the iText example but still failing. I'm using iText 7.1.15.
//open file and write to temp one
PdfDocument pdf = new(new PdfReader(FileToProcess), new PdfWriter(NewPDF), new StampingProperties().UseAppendMode());
PdfAcroForm form = PdfAcroForm.GetAcroForm(pdf, true);
XfaForm xfa = form.GetXfaForm();
XElement node = xfa.GetDatasetsNode();
IEnumerable<XNode> list = node.Nodes();
foreach (XNode item in list)
{
if (item is XElement element && "data".Equals(element.Name.LocalName))
{
node = element;
break;
}
}
XmlWriterSettings settings = new() { Indent = true };
using XmlWriter writer = XmlWriter.Create(XMLOutput, settings);
{
node.WriteTo(writer);
writer.Flush();
writer.Close();
}
//We now how to strip an extra xfa line if updating
if(update)
{
string TempXML= CSTrackerHelper.MakePath($"{AppContext.BaseDirectory}Temp", $"{Guid.NewGuid()}.XML");
StreamReader fsin = new(XMLOutput);
StreamWriter fsout = new(TempXML);
string linedata = string.Empty;
int cnt = 0;
while (!fsin.EndOfStream)
{
if (cnt != 3 && linedata != string.Empty)
{
fsout.WriteLine(linedata);
}
linedata = fsin.ReadLine();
cnt++;
}
fsout.Close();
fsin.Close();
XMLOutput = TempXML;
}
xlogger.Info("Populating pdf fields");
//Now loop through our field data and update the XML
XmlDocument xmldoc = new();
xmldoc.Load(XMLOutput);
XmlNamespaceManager xmlnsManager = new(xmldoc.NameTable);
xmlnsManager.AddNamespace("xfa", #"http://www.xfa.org/schema/xfa-data/1.0/");
string[] FieldValues;
string[] MultiNodes;
foreach (KeyValuePair<string, DocumentFieldData> v in DocumentData.FieldData)
{
if (!string.IsNullOrEmpty(v.Value.Field))
{
FieldValues = v.Value.Field.Contains(";") ? v.Value.Field.Split(';') : (new string[] { v.Value.Field });
foreach (string FValue in FieldValues)
{
XmlNodeList aNodes;
if (FValue.Contains("{"))
{
aNodes = xmldoc.SelectNodes(FValue.Substring(0, FValue.LastIndexOf("{")), xmlnsManager);
if (aNodes.Count > 1)
{
//We have a multinode
MultiNodes = FValue.Split('{');
int NodeIndex = int.Parse(MultiNodes[1].Replace("}", ""));
aNodes[NodeIndex].InnerText = v.Value.Data;
}
}
else
{
aNodes = xmldoc.SelectNodes(FValue, xmlnsManager);
if (aNodes.Count >= 1)
{
aNodes[0].InnerText = v.Value.Data;
}
}
}
}
}
xmldoc.Save(XMLOutput);
//Now we've updated the XML apply it to the pdf
xfa.FillXfaForm(new FileStream(XMLOutput, FileMode.Open, FileAccess.Read));
xfa.Write(pdf);
pdf.Close();
FYI I've also tried to set a field directly also with the same results.
PdfReader preader = new PdfReader(source);
PdfDocument pdfDoc=new PdfDocument(preader, new PdfWriter(dest), new StampingProperties().UseAppendMode());
PdfAcroForm pdfForm = PdfAcroForm.GetAcroForm(pdfDoc, true);
XfaForm xform = pdfForm.GetXfaForm();
xform.SetXfaFieldValue("VRM[0].CoverPage[0].Wrap2[0].Table[0].CSID[0]", "Test");
xform.Write(pdfForm);
pdfDoc.Close();
If anyone has any ideas it would be appreciated.
Cheers
I ran into a very similar issue. I was attempting to auto fill an XFA that was password protected while not breaking the certificate or usage rights (it allowed filling). iText7 seems to have made this not possible for legal/practical reasons, however it is still very much possible with iText5. I wrote the following working codeusing iTextSharp (C# version if iText5):
using iTextSharp.text;
using iTextSharp.text.pdf;
string pathToRead = "/Users/home/Desktop/c#pdfParser/encrypted_empty.pdf";
string pathToSave = "/Users/home/Desktop/c#pdfParser/xfa_encrypted_filled.pdf";
string data = "/Users/home/Desktop/c#pdfParser/sample_data.xml";
FillByItextSharp5(pathToRead, pathToSave, data);
static void FillByItextSharp5(string pathToRead, string pathToSave, string data)
{
using (FileStream pdf = new FileStream(pathToRead, FileMode.Open))
using (FileStream xml = new FileStream(data, FileMode.Open))
using (FileStream filledPdf = new FileStream(pathToSave, FileMode.Create))
{
PdfReader.unethicalreading = true;
PdfReader pdfReader = new PdfReader(pdf);
PdfStamper stamper = new PdfStamper(pdfReader, filledPdf, '\0', true);
stamper.AcroFields.Xfa.FillXfaForm(xml, true);
stamper.Close();
pdfReader.Close();
}
}
PdfStamper stamper = new PdfStamper(pdfReader, filledPdf, '\0', true)
you have to use this line.
We have to rework how we're sending emails since we are using Amazon SES. In the past, we were using smtp but can't do that in this case. The class that needs updated has taken in a MailMessage object and used smtp to send it. So I'm trying to rework the method to be able to continue to accept the MailMessage object and convert it to a MimeKit MimeMessage. For the most part it's working fine except when it comes to attachments. In the code I have, the attachment gets added and sent, however, when trying to open it appears it's corrupted or something. In my test case I attached a csv file. I could not open it in excel after receiving the email.
public class EmailAbstraction
{
public virtual void Send(MailMessage mailMessage)
{
sendMessage(mailMessage);
}
private static void sendMessage(MailMessage mailMessage)
{
using (var client = new AmazonSimpleEmailServiceClient(AwsConstants.SESAWSKey, AwsConstants.SESAWSSecret, AwsConstants.RegionEndpoint))
{
foreach (var to in mailMessage.To)
{
using (var messageStream = new MemoryStream())
{
var newMessage = new MimeMessage();
var builder = new BodyBuilder
{
HtmlBody = mailMessage.Body
};
newMessage.From.Add(mailMessage.From == null
? new MailboxAddress(EmailConstants.DefaultFromEmailDisplayName, EmailConstants.DefaultFromEmailAddress)
: new MailboxAddress(mailMessage.From.Address));
newMessage.To.Add(new MailboxAddress(to.DisplayName, to.Address));
newMessage.Subject = mailMessage.Subject;
foreach (var attachment in mailMessage.Attachments)
{
builder.Attachments.Add(attachment.Name, attachment.ContentStream);
}
newMessage.Body = builder.ToMessageBody();
newMessage.WriteTo(messageStream);
var request = new SendRawEmailRequest
{
RawMessage = new RawMessage { Data = messageStream }
};
client.SendRawEmail(request);
}
}
}
}
}
And in my test app, I have this.
internal class Program
{
private static void Main(string[] args)
{
var s = GetFileStream();
var m = new MailMessage();
var sender = new MailAddress("info#ourwebsite.com", "info");
m.From = sender;
m.Sender = sender;
m.Body = "test email";
m.Subject = "test subject";
m.To.Add(myemail);
m.Attachments.Add(new Attachment(s, "test-file.csv"));
new EmailAbstraction().Send(m);
}
private static MemoryStream GetFileStream()
{
var stream = new MemoryStream();
var fileStream = File.Open(#"C:\Users\dev\Desktop\test-file.csv", FileMode.Open);
fileStream.CopyTo(stream);
fileStream.Close();
return stream;
}
}
This is just copied from the MimeKit source code:
static MimePart GetMimePart (System.Net.Mail.AttachmentBase item)
{
var mimeType = item.ContentType.ToString ();
var contentType = ContentType.Parse (mimeType);
var attachment = item as System.Net.Mail.Attachment;
MimePart part;
if (contentType.MediaType.Equals ("text", StringComparison.OrdinalIgnoreCase))
part = new TextPart (contentType);
else
part = new MimePart (contentType);
if (attachment != null) {
var disposition = attachment.ContentDisposition.ToString ();
part.ContentDisposition = ContentDisposition.Parse (disposition);
}
switch (item.TransferEncoding) {
case System.Net.Mime.TransferEncoding.QuotedPrintable:
part.ContentTransferEncoding = ContentEncoding.QuotedPrintable;
break;
case System.Net.Mime.TransferEncoding.Base64:
part.ContentTransferEncoding = ContentEncoding.Base64;
break;
case System.Net.Mime.TransferEncoding.SevenBit:
part.ContentTransferEncoding = ContentEncoding.SevenBit;
break;
//case System.Net.Mime.TransferEncoding.EightBit:
// part.ContentTransferEncoding = ContentEncoding.EightBit;
// break;
}
if (item.ContentId != null)
part.ContentId = item.ContentId;
var stream = new MemoryStream ();
item.ContentStream.CopyTo (stream);
stream.Position = 0;
part.Content = new MimeContent (stream);
return part;
}
I'm using iText 5 to fill existing pdf forms with content and then merge them into a single pdf. I also want to turn on/off layers, but after merging all layers are visible.
This code shows the problem without using existing pdf forms. I would like to hide layer two but it seems not working.
static void Main(string[] args)
{
byte[] pdfPage = CreatePage();
byte[] result = Merge(new byte[][] { pdfPage, pdfPage });
File.WriteAllBytes(#"c:\test1.pdf", result);
}
private static byte[] CreatePage()
{
Document doc = new Document();
MemoryStream ms = new MemoryStream();
PdfWriter writer = PdfWriter.GetInstance(doc, ms);
doc.Open();
PdfLayer layer1 = new PdfLayer("Layer 1", writer);
PdfLayer layer2 = new PdfLayer("Layer 2", writer);
PdfContentByte cb = writer.DirectContent;
cb.BeginLayer(layer1);
ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase("Layertext 1"), 100, 700, 0);
cb.EndLayer();
cb.BeginLayer(layer2);
ColumnText.ShowTextAligned(cb, Element.ALIGN_LEFT, new Phrase("Layertext 2"), 100, 600, 0);
cb.EndLayer();
layer1.On = true;
// turn off layer 2
layer2.On = false;
doc.Close();
return ms.ToArray();
}
private static byte[] Merge(byte[][] pages)
{
Document doc = new Document();
MemoryStream ms = null;
using (ms = new MemoryStream())
{
PdfCopy copy = new PdfCopy(doc, ms);
doc.Open();
foreach (byte[] page in pages)
{
PdfReader reader = new PdfReader(new MemoryStream(page));
PdfImportedPage imp = copy.GetImportedPage(reader, 1);
copy.AddPage(imp);
reader.Close();
}
doc.Close();
}
return ms.ToArray();
}
I want to export razor view to pdf by using the itextsharp library. The problem is that some turkish characters such as İ,ı,Ş,ş etc... are missing in the pdf document. The code used to export the pdf is:
public PdfActionResult(object model)
{
Model = model;
}
public override void ExecuteResult(ControllerContext context)
{
IView viewEngineResult;
ViewContext viewContext;
if (ViewName == null)
{
ViewName = context.RouteData.GetRequiredString("action");
}
context.Controller.ViewData.Model = Model;
var workStream = new MemoryStream();
var document = new Document();
PdfWriter writer = PdfWriter.GetInstance(document, workStream);
writer.CloseStream = false;
document.Open();
viewEngineResult = ViewEngines.Engines.FindView(context, ViewName, null).View;
var sb = new StringBuilder();
TextWriter tr = new StringWriter(sb);
viewContext = new ViewContext(context, viewEngineResult, context.Controller.ViewData,
context.Controller.TempData, tr);
viewEngineResult.Render(viewContext, tr);
CultureInfo ci = new CultureInfo("az-Latn-AZ");
Encoding enc = Encoding.GetEncoding(ci.TextInfo.ANSICodePage);
Stream stream = new MemoryStream(enc.GetBytes(sb.ToString()));
XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, stream, null);
document.Close();
new FileContentResult(workStream.ToArray(), "application/pdf").ExecuteResult(context);
}
}
Then I access it as:
public ActionResult StudentPdf(Guid studentId)
{
var model = _studentRepository.GetByIdGuid(studentId);
return new PdfActionResult(model);
}
Thanks for reply
by this way you can print all turkish character.
String htmlText = html.ToString();
Document document = new Document();
string filePath = HostingEnvironment.MapPath("~/Content/Pdf/");
PdfWriter.GetInstance(document, new FileStream(filePath + "\\pdf-"+Name+".pdf", FileMode.Create));
document.Open();
iTextSharp.text.html.simpleparser.HTMLWorker hw = new iTextSharp.text.html.simpleparser.HTMLWorker(document);
FontFactory.Register(Path.Combine(_webHelper.MapPath("~/App_Data/Pdf/arial.ttf")), "Garamond"); // just give a path of arial.ttf
StyleSheet css = new StyleSheet();
css.LoadTagStyle("body", "face", "Garamond");
css.LoadTagStyle("body", "encoding", "Identity-H");
css.LoadTagStyle("body", "size", "12pt");
hw.SetStyleSheet(css);
hw.Parse(new StringReader(htmlText));
Hope this helps

After a long time of struggling with this not-so-friendly API, I am finally making progress, but now I've come to a really nasty issue.. I have placed "dir" attributes in various places in my html with the value being "rtl".. but the XMLWorker doesn't seem to respect that at all. Does anyone know of a workaround? Here's my method:
public static void Generate<TModel>(string templateFile, TModel model, string outputFile, IEnumerable<string> fonts)
{
string template = System.IO.File.ReadAllText(templateFile);
string result = Razor.Parse(template, model);
using (var fsOut = new FileStream(outputFile, FileMode.Create, FileAccess.Write))
using (var stringReader = new StringReader(result))
{
var document = new Document();
var pdfWriter = PdfWriter.GetInstance(document, fsOut);
pdfWriter.InitialLeading = 12.5f;
document.Open();
var xmlWorkerHelper = XMLWorkerHelper.GetInstance();
var cssResolver = new StyleAttrCSSResolver();
//cssResolver.AddCss(cssFile);
var xmlWorkerFontProvider = new XMLWorkerFontProvider();
foreach (string font in fonts)
{
xmlWorkerFontProvider.Register(font);
}
var cssAppliers = new CssAppliersImpl(xmlWorkerFontProvider);
var htmlContext = new HtmlPipelineContext(cssAppliers);
htmlContext.SetTagFactory(Tags.GetHtmlTagProcessorFactory());
PdfWriterPipeline pdfWriterPipeline = new PdfWriterPipeline(document, pdfWriter);
HtmlPipeline htmlPipeline = new HtmlPipeline(htmlContext, pdfWriterPipeline);
CssResolverPipeline cssResolverPipeline = new CssResolverPipeline(cssResolver, htmlPipeline);
XMLWorker xmlWorker = new XMLWorker(cssResolverPipeline, true);
XMLParser xmlParser = new XMLParser(xmlWorker);
xmlParser.Parse(stringReader);
document.Close();
}
}
I've created a sample to show how to parse and display RTL data using XMLWorker. Download it from here.
