With " target"_blank">PDF .Net, you can get, create, remove or reorder PDF document pages in your C# or VB.NET application.
The pages of a PDF document are accessed through a structure known as the page tree, which defines the ordering of pages in the document. The tree structure allows PDF consumer applications, using only limited memory, to quickly open a
PDF document containing thousands of pages. For more information, see Document Structure help page.
The following example shows how you can create a page tree structure from scratch.
using System
using SautinSoft.Pdf
using System.IO
class Program
{
static void Main()
{
// This property is necessary only for licensed version.
//SautinSoft.Pdf.Serial "XXXXXXXXXXX"
using (var document new PdfDocument())
{
using (var formattedText new PdfFormattedText())
{
// Get a page tree root node.
var rootNode document.Pages
// Set page rotation for a whole set of pages.
rootNode.Rotate 90
// Create a left page tree node.
var childNode rootNode.Kids.AddPages()
// Overwrite a parent tree node rotation value.
childNode.Rotate 0
// Create a first page.
var page childNode.Kids.AddPage()
formattedText.Append("FIRST PAGE")
page.Content.DrawText(formattedText, new PdfPoint(0, 0))
// Create a second page and set a page media box value.
page childNode.Kids.AddPage()
page.SetMediaBox(0, 0, 200, 400)
formattedText.Clear()
formattedText.Append("SECOND PAGE")
page.Content.DrawText(formattedText, new PdfPoint(0, 0))
// Create a right page tree node.
childNode rootNode.Kids.AddPages()
// Set a media box value.
childNode.SetMediaBox(0, 0, 100, 200)
// Create a third page.
page childNode.Kids.AddPage()
formattedText.Clear()
formattedText.Append("THIRD PAGE")
page.Content.DrawText(formattedText, new PdfPoint(0, 0))
// Create a fourth page and overwrite a rotation value.
page childNode.Kids.AddPage()
page.Rotate 0
formattedText.Clear()
formattedText.Append("FOURTH PAGE")
page.Content.DrawText(formattedText, new PdfPoint(0, 0))
}
document.Save("Page Tree.pdf")
}
}
