List of the following feature

Create new PDF document

This example will demonstrate how you can easily create a new PDF document and add some text and images to it.

  • PdfDocument pdfDocument = new PdfDocument();
  • var page = pdfDocument.AddPage();
  • page.Size = PdfEdit.PageSize.A4;
  • XGraphics gfx = XGraphics.FromPdfPage(page);
  • gfx.DrawString("How deep is the rabbit hole?", new XFont("Ariel", 10), XBrushes.Blue, new PointF(100, 100));
  • XImage image = XImage.FromFile(@"c:\images2\w3c_home.jpg");
  • gfx.DrawImage(image, new Point(300, 300));
  • gfx.Dispose();
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test.pdf");

Add pages to existing PDF document

Here we will take an existing PDF document and append additional pages to it. The newly appended pages will not contain any content.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Modify);
  • var newPage = pdfDocument.AddPage();
  • var newPage2 = pdfDocument.AddPage();
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test.pdf");

Edit existing PDF document

In this case, we take an existing document and insert a watermark on every page. This example uses a text message as the watermark, but you can just as easily insert an image.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Modify);
  • foreach(var page in pdfDocument.Pages)
  • {
  • 	XGraphics gfx = XGraphics.FromPdfPage(page);
  • 	gfx.DrawString("Lets pretend this is a watermark message...", new XFont(this.Font.FontFamily.Name, 10),
                                                                        XBrushes.Red,  new PointF(50, 50));
  • 	XImage image = XImage.FromFile(@"c:\images\w3c_home.bmp");
  • 	gfx.DrawImage(image, new Point(150, 150));
  • 	gfx.Dispose();
  • }
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test.pdf");

Remove pages from PDF document

Now we will open a PDF document, check if it contains at least two pages and if yes remove the second page.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Modify);
  • if (pdfDocument.Pages.Count > 1)
  • 	pdfDocument.Pages.RemoveAt(1); // remove second page
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test.pdf");

Extracts pages from PDF document

Let's try now to extract every second page from an existing document. This code would create a new document which would contain every second page from the original document. The original document would stay unharmed.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Import);
  • PdfDocument newPdfDocument = new PdfDocument();
  • for (int i = 0; i < pdfDocument.Pages.Count; i++)            
  • 	if ((i + 1) % 2 == 0)
  • 		newPdfDocument.AddPage(pdfDocument.Pages[i]);
  • newPdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • newPdfDocument.Save(@"c:\test\test2.pdf");

Protect PDF document and set user access permission

Let's now open an existing document, encrypt it with AES256, change the user access permission and secure it with a username and password. As you can see from the code we, for example, disabled full quality prints and form fills.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Modify);
  • pdfDocument.SecuritySettings.PdfDocumentEncryptionAlgorithm = new EncryptionAlgorithmInfo();
  • pdfDocument.SecuritySettings.PdfDocumentEncryptionAlgorithm.Type = PdfDocumentSecurityLevel.AES_256;
  • // user access permissions
  • pdfDocument.SecuritySettings.OwnerPassword = "ownerPass";
  • pdfDocument.SecuritySettings.UserPassword = "userPass";
  • pdfDocument.SecuritySettings.PermitAccessibilityExtractContent = true;
  • pdfDocument.SecuritySettings.PermitAnnotations = true;
  • pdfDocument.SecuritySettings.PermitAssembleDocument = true;
  • pdfDocument.SecuritySettings.PermitExtractContent = true;
  • pdfDocument.SecuritySettings.PermitFormsFill = false;
  • pdfDocument.SecuritySettings.PermitFullQualityPrint = false;
  • pdfDocument.SecuritySettings.PermitModifyDocument = true;
  • pdfDocument.SecuritySettings.PermitPrint = true;
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test.pdf");        

Fill in a PDF form

Now let's fill in text fields of a PDF form. Changes will be saved into a separate document and the original document will stay unmodified.

  • PdfDocument pdfDocument = PdfReader.Open(@"c:\test\test.pdf", PdfDocumentOpenMode.Modify);
  • var  textField = (pdfDocument.AcroForm.Fields["FieldSubjectType"] as PdfTextField);  // get field by name or index
  • if (!textField.ReadOnly)
  • 	textField.Text = "Top Secret";
  • pdfDocument.SetLicenseInfo("companyName", "licenseKey");
  • pdfDocument.Save(@"c:\test\test2.pdf");
