While using pdfSweep, it's redacting more text than it's supposed to. Why is it redacting "JS" as well?
PdfDocument pdfDoc = new PdfDocument(reader, writer);
CompositeCleanupStrategy cleanupStrategy = new CompositeCleanupStrategy();
cleanupStrategy.add(new RegexBasedCleanupStrategy("032016"));
cleanupStrategy.add(new RegexBasedCleanupStrategy("123123123"));
PdfAutoSweep autoSweep = new PdfAutoSweep(cleanupStrategy);
autoSweep.cleanUp(pdfDoc);

PdfReader reader = new PdfReader(sourceXfaPath);
PdfWriter writer = new PdfWriter(exportPdf);
PdfDocument pdfDoc = new PdfDocument(reader, writer, new StampingProperties().UseAppendMode());
PdfAcroForm form = PdfAcroForm.GetAcroForm(pdfDoc, true);
XfaForm xfa = form.GetXfaForm();
xfa.FillXfaForm(new FileStream(exportXfaXml,FileMode.Open));
xfa.Write(pdfDoc);
pdfDoc.Close();
reader.Close();
codes are above:
but it doesn't create pdf document, I'm not sure why it doesn't create it.
I just tried xfa.FillXfaForm(new FileStream(exportXfaXml,FileMode.Open)); to xfa.FillXfaForm(XmlReader.Create(path));
but it shows me same error
public void customGenerate(string sourceFilePath, string destinationtFilePath, string replacementXmlFilePath)
{
PdfReader pdfReader = new PdfReader(sourceFilePath);
using (MemoryStream ms = new MemoryStream())
{
using (PdfStamper stamper = new PdfStamper(pdfReader, ms, '\0', true))
//using (PdfStamper stamper = new PdfStamper(pdfReader, ms))
{
XfaForm xfaForm = new XfaForm(pdfReader);
XmlDocument doc = new XmlDocument();
doc.Load(replacementXmlFilePath);
xfaForm.DomDocument = doc;
xfaForm.Changed = true;
XfaForm.SetXfa(xfaForm, stamper.Reader, stamper.Writer);
stamper.Close();
}
var bytes = ms.ToArray();
System.IO.File.WriteAllBytes(destinationtFilePath, bytes);
ms.Close();
}
pdfReader.Close();
}
This is my code to add Javacript to XFA PDF.
I'm going to add JavaScript[handle button , checkbox] to XFA pdf with avoid signature.
i'm trying to create a pdf using PdfSharpCore for Xamarin Forms but I've run into some issues.
private void CreatePdf(object sender)
{
PdfDocument pdf = new PdfDocument();
PdfPage pdfPage = pdf.AddPage();
XGraphics graph = XGraphics.FromPdfPage(pdfPage);
XFont font = new XFont("Verdana", 20, XFontStyle.Bold);
graph.DrawString("This is my first PDF document", font, XBrushes.Black, new XRect(0, 0, pdfPage.Width.Point, pdfPage.Height.Point), XStringFormats.TopLeft);
string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
string localFilename = "test.pdf";
string localPath = Path.Combine(documentsPath, localFilename);
MemoryStream stream = new MemoryStream();
pdf.Save(stream, false);
byte[] bytes = stream.ToArray();
File.WriteAllBytes(localPath, bytes);
}
This is my function that generate the pdf and save it but when I press the button that invoke it, nothing happens.
I've already add the the permissions on the AndroidManifest.xml file like this:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
I've tried using a library called Xamarin.Forms.SaveOpenPDFPackage. With this library you can
save and open your brand new pdf by doing this:
await CrossXamarinFormsSaveOpenPDFPackage.Current.SaveAndView("myFile1.pdf", "application/pdf", stream, PDFOpenContext.InApp);
It half works: it opens my new pdf but it doesn't save it.
Do you have any tip?
You could try to use Syncfusion.Xamarin.PDF.
Install from NuGet package first.
Creating a PDF document with table:
//Create a new PDF document.
PdfDocument doc = new PdfDocument();
//Add a page.
PdfPage page = doc.Pages.Add();
//Create a PdfGrid.
PdfGrid pdfGrid = new PdfGrid();
//Add values to list
List<object> data = new List<object>();
Object row1 = new { ID = "E01", Name = "Clay" };
Object row2 = new { ID = "E02", Name = "Thomas" };
Object row3 = new { ID = "E03", Name = "Andrew" };
Object row4 = new { ID = "E04", Name = "Paul" };
Object row5 = new { ID = "E05", Name = "Gray" };
data.Add(row1);
data.Add(row2);
data.Add(row3);
data.Add(row4);
data.Add(row5);
//Add list to IEnumerable
IEnumerable<object> dataTable = data;
//Assign data source.
pdfGrid.DataSource = dataTable;
//Draw grid to the page of PDF document.
pdfGrid.Draw(page, new PointF(10, 10));
//Save the PDF document to stream.
MemoryStream stream = new MemoryStream();
doc.Save(stream);
//Close the document.
doc.Close(true);
//Save the stream as a file in the device and invoke it for viewing
Xamarin.Forms.DependencyService.Get<ISave>().SaveAndView("Output.pdf", "application/pdf", stream);
For more details about the ISave, you could get the whole code from Syncfusion official document.
I have been trying to make an application that invokes camera through page rendering. I have used Custom Renderer from Xamarin. My problem is I need to send the picture to the other page/activity in the "Native" after clicking, but currently it is saving the picture in the gallery of the device.
For example: I click the image and then the image gets displayed with the message "Do you want to save it?". This has to be done in native rather than PCL. I have been trying through intent but that doesn't work.
All my code right now doing is saving the image to the gallery.
try
{
var absolutePath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDcim).AbsolutePath;
var folderPath = absolutePath + "/Camera";
var filePath = System.IO.Path.Combine(folderPath, string.Format("photo_{0}.jpg", Guid.NewGuid()));
var fileStream = new FileStream(filePath, FileMode.Create);
await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 100, fileStream);
fileStream.Close();
image.Recycle();
// imageByte = ((byte[])image);
var intent = new Android.Content.Intent(Android.Content.Intent.ActionMediaScannerScanFile);
var file = new Java.IO.File(filePath);
var uri = Android.Net.Uri.FromFile(file);
intent.SetData(uri);
//intent.PutExtra("image", imageByte);
MainActivity.Instances.SendBroadcast(intent);
}
Solved it. Passing bitmap through intent.
Activity 1:
byte[] imageByte;
var image = textureView.Bitmap;
MemoryStream memStream = new MemoryStream();
// ByteArrayOutputStream _bs = new ByteArrayOutputStream();
await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 100, memStream);
imageByte = memStream.ToArray();
Intent i = new Intent(this.Context, typeof(CameraDisplay));
i.PutExtra("image", imageByte);
activity.StartActivity(i);
Activity 2:
byte[] Image = Intent.GetByteArrayExtra("image");
imageView = FindViewById(Resource.Id.imageView1);
Bitmap bitmap = BitmapFactory.DecodeByteArray(Image, 0, Image.Length);
imageView.SetImageBitmap(bitmap);
I need to insert an image into an existing pdf at a specific location. I tried the answer at this question. But whatever different ways I do the image is being inserted at (0,0) position (bottom left corner). I tried another approach where instead of using stream I used Document class in iTextSharp as shown here. Now I am able to place the image at the desired position but this method is creating a new document with just this image. Most of the articles I searched are using PdfReader and PdfStamper so I think this is the recommended way. Any help is appreciated. Posting below code for both the methods I tried.
PdfStamper method
private void AddImage(string filePath)
{
string imageURL = #"ImagePath\Image.jpg";
using (Stream inputPdfStream = new FileStream(filePath, FileMode.Open, FileAccess.Read))
using (Stream inputImageStream = new FileStream(imageURL, FileMode.Open, FileAccess.Read))
using (Stream outputPdfStream = new FileStream(#"ResultingPdfPath\Abcd.pdf", FileMode.Create, FileAccess.ReadWrite))
{
Image image = Image.GetInstance(inputImageStream);
image.ScaleToFit(100, 100);
var reader = new PdfReader(inputPdfStream);
var stamper = new PdfStamper(reader, outputPdfStream);
PdfContentByte content = stamper.GetUnderContent(1);
image.SetAbsolutePosition(100f, 150f);
content.AddImage(image);
stamper.Close();
reader.Close();
}
}
Document class method
private void TestMessage(string filePath)
{
string imageURL = #"ImagePath\Image.jpg";
Document doc = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(filePath, FileMode.Open));
doc.Open();
iTextSharp.text.Image jpg = iTextSharp.text.Image.GetInstance(imageURL);
jpg.ScaleToFit(140f, 120f);
jpg.SetAbsolutePosition(100, 100);
jpg.SpacingBefore = 10f;
jpg.SpacingAfter = 1f;
jpg.Alignment = Element.ALIGN_LEFT;
doc.Add(jpg);
doc.Close();
}
Let me know if you need further information.
I adapted your method to accept variable out paths and positions and tested it with iTextSharp 5.5.7 like this:
[TestFixture]
class TestInsertImage
{
/// iText stamp image on top not always working
/// http://stackoverflow.com/questions/33898280/itext-stamp-image-on-top-not-always-working

public void AddStampToTestPdf()
{
Directory.CreateDirectory(#"C:\Temp\test-results\content\");
AddImage(#"d:\Issues\stackoverflow\iText stamp image on top not always working\Multipage.pdf", #"C:\Temp\test-results\content\Multipage-stamp-Image-100-150.pdf", 100f, 150f);
AddImage(#"d:\Issues\stackoverflow\iText stamp image on top not always working\Multipage.pdf", #"C:\Temp\test-results\content\Multipage-stamp-Image-150-100.pdf", 150f, 100f);
}
private void AddImage(string filePath, string outPath, float x, float y)
{
string imageURL = #"c:\Repo\GitHub\testarea\itext5\src\test\resources\mkl\testarea\itext5\layer\Willi-1.jpg";
using (Stream inputPdfStream = new FileStream(filePath, FileMode.Open, FileAccess.Read))
using (Stream inputImageStream = new FileStream(imageURL, FileMode.Open, FileAccess.Read))
using (Stream outputPdfStream = new FileStream(outPath, FileMode.Create, FileAccess.ReadWrite))
{
Image image = Image.GetInstance(inputImageStream);
image.ScaleToFit(100, 100);
var reader = new PdfReader(inputPdfStream);
var stamper = new PdfStamper(reader, outputPdfStream);
PdfContentByte content = stamper.GetUnderContent(1);
image.SetAbsolutePosition(x, y);
content.AddImage(image);
stamper.Close();
reader.Close();
}
}
}
The results are included below.
As you see, the positioning information clearly are respected, and the image is definitely not always at the bottom left corner.

I have a .pdf file stored in my database, and I have a signature file (.png) stored in my database. I am trying to use iTextSharp to add the signature image to the .pdf file, and display the result to the browser.
Here is my code:
byte[] file = Repo.GetDocumentBytes(applicantApplication.ApplicationID, documentID);
byte[] signatureBytes = Repo.GetSignatureBytes((Guid)applicantApplicationID, signatureID);
iTextSharp.text.Image signatureImage = iTextSharp.text.Image.GetInstance(signatureBytes);
iTextSharp.text.Document document = new iTextSharp.text.Document();
using (System.IO.MemoryStream ms = new System.IO.MemoryStream(file, 0, file.Length, true, true))
{
PdfWriter writer = PdfWriter.GetInstance(document, ms);
document.Open();
signatureImage.SetAbsolutePosition(200, 200);
signatureImage.ScaleAbsolute(200, 50);
document.Add(signatureImage);
document.Close();
return File(ms.GetBuffer(), "application/pdf");
}
The page loads, and there is a .pdf with a signature, but the original document is nowhere to be found. It looks like I'm creating a new .pdf file and putting the image in there instead of editing the old .pdf file.
I have verified that the original .pdf document is being loaded into the "file" variable. I have also verified that the length of the MemoryStream "ms" is the same as the length of the byte[] "file".
I ended up doing something like this in my repository:
using (Stream inputPdfStream = new MemoryStream(file, 0, file.Length, true, true))
using (Stream inputImageStream = new MemoryStream(signatureBytes, 0, signatureBytes.Length, true, true))
using (MemoryStream outputPdfStream = new MemoryStream())
{
var reader = new PdfReader(inputPdfStream);
var stamper = new PdfStamper(reader, outputPdfStream);
var cb = stamper.GetOverContent(1);
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(inputImageStream);
image.SetAbsolutePosition(400, 100);
image.ScaleAbsolute(200, 50);
cb.AddImage(image);
stamper.Close();
return outputPdfStream.GetBuffer();
}
I adapted it from a few other answers on StackOverflow
