Paged HTML Example

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#]
Doc theDoc = new Doc();
theDoc.Rect.Inset(72, 144);
theDoc.HtmlOptions.UseScript = false; // set to true if your layout is JavaScript dependent

[Visual Basic]
Dim theDoc As Doc = New Doc()
theDoc.Rect.Inset(72, 144)
theDoc.HtmlOptions.UseScript = False ' set to true if your layout is JavaScript dependent

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

[C#]
theDoc.Page = theDoc.AddPage();
int theID;
theID = theDoc.AddImageUrl("http://www.yahoo.com/");

[Visual Basic]
theDoc.Page = theDoc.AddPage()
Dim theID As Integer
theID = theDoc.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) {
  theDoc.FrameRect(); // add a black border
  if (!theDoc.Chainable(theID))
    break;
  theDoc.Page = theDoc.AddPage();
  theID = theDoc.AddImageToChain(theID);
}

[Visual Basic]
While True
  theDoc.FrameRect() ' add a black border
  If Not theDoc.Chainable(theID) Then
    Exit While
  End If
  theDoc.Page = theDoc.AddPage()
  theID = theDoc.AddImageToChain(theID)
End While

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 <= theDoc.PageCount; i++) {
  theDoc.PageNumber = i;
  theDoc.Flatten();
}

[Visual Basic]
For i As Integer = 1 To theDoc.PageCount
  theDoc.PageNumber = i
  theDoc.Flatten()
Next

Finally we save.

[C#]
theDoc.Save(Server.MapPath("pagedhtml.pdf"));
theDoc.Clear();

[Visual Basic]
theDoc.Save(Server.MapPath("pagedhtml.pdf"))
theDoc.Clear()


We get the following output.

pagedhtml.pdf [Page 1]

pagedhtml.pdf [Page 2]
