This example shows how to import an HTML page into a multi-page PDF document.

We first create a Doc object and inset the edges a little so that the HTML will appear in the middle of the page.

[C#]

using (Doc doc = new Doc()) {
  doc.Rect.Inset(72, 144);

Using doc As New Doc()
  doc.Rect.Inset(72, 144)

We set some HTML options to choose the HTML engine and features we are interested in. The defaults assigned here are set up for ease of development and you may wish to change some for release.

[C#]

  doc.HtmlOptions.Engine = EngineType.Chrome86;
  doc.HtmlOptions.UseScript = true; // enable JavaScript
  doc.HtmlOptions.Media = MediaType.Print; // Or Screen for a more screen oriented output
  doc.HtmlOptions.InitialWidth = 800; // In case we have a responsive site which is non-specific on good widths
  //doc.HtmlOptions.RepaintDelay = 500; // Only required if you have AJAX or animated content such as graphs
  //doc.HtmlOptions.IgnoreCertificateErrors = false; // Disabled for ease of debugging
  //doc.HtmlOptions.FireShield.Policy = XHtmlFireShield.Enforcement.Deny; // Disabled for ease of debugging

  doc.HtmlOptions.Engine = EngineType.Chrome86
  doc.HtmlOptions.UseScript = True ' enable JavaScript
  doc.HtmlOptions.Media = MediaType.Print ' Or Screen for a more screen oriented output
  doc.HtmlOptions.InitialWidth = 800 ' In case we have a responsive site which is non-specific on good widths
  'doc.HtmlOptions.RepaintDelay = 500; // Only required if you have AJAX or animated content such as graphs
  'doc.HtmlOptions.IgnoreCertificateErrors = false; // Disabled for ease of debugging
  'doc.HtmlOptions.FireShield.Policy = XHtmlFireShield.Enforcement.Deny; // Disabled for ease of debugging

We add the first page of HTML. We save the returned ID as this will be used to add subsequent pages.

[C#]

  doc.Page = doc.AddPage();
  int theID;
  theID = doc.AddImageUrl("http://www.yahoo.com/");

  doc.Page = doc.AddPage()
  Dim theID As Integer
  theID = doc.AddImageUrl("http://www.yahoo.com/")

We now chain subsequent pages together. We stop when we reach a page which wasn't truncated.

[C#]

  while (true) {
    doc.FrameRect(); // add a black border
    if (!doc.Chainable(theID))
      break;
    doc.Page = doc.AddPage();
    theID = doc.AddImageToChain(theID);
  }

  Do
    doc.FrameRect() ' add a black border
    If Not doc.Chainable(theID) Then
      Exit Do
    End If
    doc.Page = doc.AddPage()
    theID = doc.AddImageToChain(theID)
  Loop

After adding the pages we can flatten them. We can't do this until after the pages have been added because flattening will invalidate our previous ID and break the chain.

[C#]

  for (int i = 1; i <= doc.PageCount; i++) {
    doc.PageNumber = i;
    doc.Flatten();
  }

  For i As Integer = 1 To doc.PageCount
    doc.PageNumber = i
    doc.Flatten()
  Next i

Finally we save.

[C#]

  doc.Save(Server.MapPath("pagedhtml.pdf"));
}

  doc.Save(Server.MapPath("pagedhtml.pdf"))
End Using

We get the following output.

pagedhtml.pdf [Page 1]

pagedhtml.pdf [Page 2]
