Create a new 8.5x11 blank page and add it to the end of the document page sequence.
Note that after a page is created, it does not yet belong to the page sequence of the document. In order for the page to become "visible," it must be placed within the page sequence; PagePushBack() inserts page x at the last page position in the document.
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())
{
// Create a new page
var page = document.Pages.Add();
document.PagePushBack(x);
}
document.Save("Empty.pdf");
}
}
To create a new page, use the document.Pages.Add (media_box) method. Pages.Add() takes an optional Rect argument that can be used to specify page size. This Rect is called a media box.
The media box is a rectangle, represented in default user space units, that defines the boundaries of the physical medium on which the page will be displayed or printed. The user space unit is 1/72 inch; if media_box is not specified, the default dimensions of the page are 8.5 x 11 inches (or 8.5*72, 11*72 units).
To split a PDF document into multiple pages.

using System.IO;

int page_num = doc.GetPageCount();
for (int i = 1; i <= page_num; ++i)
{
var new_document = new PdfDocument();
new_document.InsertPages(0, document, i, i, PdfDocument.InsertFlag.e_none);
new_document.Save(output_filename + "_split_page_" + i + ".pdf", SaveOptions.e_linearized);
}
}
}

Reverse the order of pages and rearrange pages in a PDF document. Given the page copy and delete operations described in other sections, rearranging and reordering pages is straightforward.
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";
PdfDocument doc = new PdfDocument(filename);
int page_num = doc.GetPageCount();
for (int i=1; i<=page_num; ++i)
{
PageIterator itr = doc.GetPageIterator(i);
Page page = itr.Current();
doc.PageRemove(itr);
doc.PagePushFront(page);
}
}
}
To remove pages from a PDF document.
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";
PdfDocument doc = new PdfDocument(filename);
// Remove the fifth page from the page sequence.
doc.PageRemove(doc.GetPageIterator(5));
// Remove the third page.
PageIterator i = doc.GetPageIterator();
i.Next();
i.Next();
doc.PageRemove(i);
}
}
To crop a page in a PDF document.
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";
PdfDocument doc = new PdfDocument(filename);
// Access a PDF page
Page page = doc.GetPage(page_num);
// Crop the page
page.SetCropBox(new Rect(0, 0, 500, 600));
}
}
The crop box defines the region to which the contents of the page are to be clipped (cropped) when displayed or printed. Unlike other types of boxes, the crop box has no defined meaning in terms of physical page geometry or intended use; it merely imposes clipping on the page contents. The default value is the page's media box. A new crop box can be imposed on a page with Page.SetCropBox().
To rotate a page in a PDF document.
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";
PdfDocument doc = new PdfDocument(filename);
// Rotate the first page 90 degrees clockwise.
Page page = doc.GetPage(1);
Page.Rotate originalRotation = page.GetRotation();
Page.Rotate rotation;
switch (originalRotation)
{
case Page.Rotate.e_0: rotation = Page.Rotate.e_90; break;
case Page.Rotate.e_90: rotation = Page.Rotate.e_180; break;
case Page.Rotate.e_180: rotation = Page.Rotate.e_270; break;
case Page.Rotate.e_270: rotation = Page.Rotate.e_0; break;
default: rotation = Page.Rotate.e_0; break;
}
page.SetRotation(rotation);
}
}
