Adding a new page to the document

The following code sample explains you on how to add a PdfPage in a PDF document. When multiple pages are added, the new page is always added to the end of the document.

//Create a new PDF document.
PdfDocument document = new PdfDocument();
//Add a page.
PdfPage page = document.Pages.Add();
//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;

//Create a solid brush.
PdfBrush brush = new PdfSolidBrush(Syncfusion.Drawing.Color.Black);
//Set the font.
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 14);
//Draw the text.
graphics.DrawString("Hello world!", font, brush, new Syncfusion.Drawing.PointF(20, 20));

//Creating the stream object.
MemoryStream stream = new MemoryStream();
//Save the document as stream.
document.Save(stream);
//Close the document.
document.Close(true);
//Create a new PDF document.
PdfDocument document = new PdfDocument();
//Add a page.
PdfPage page = document.Pages.Add();
//Create PDF graphics for the page.
PdfGraphics graphics = page.Graphics;

//Create a solid brush.
PdfBrush brush = new PdfSolidBrush(Color.Black);
//Set the font.
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 14);
//Draw the text.
graphics.DrawString("Hello world!", font, brush, new PointF(20, 20));

//Save and close the document.
document.Save("Output.pdf");
document.Close(true);
'Create a new PDF document.
Dim document As New PdfDocument()
'Add a page.
Dim page As PdfPage = document.Pages.Add()
'Create PDF graphics for the page.
Dim graphics As PdfGraphics = page.Graphics

'Create a solid brush.
Dim brush As PdfBrush = New PdfSolidBrush(Color.Black)
'Set the font.
Dim font As PdfFont = New PdfStandardFont(PdfFontFamily.Helvetica, 14)

Splitting a PDF file to individual pages

Essential PDF allows to split the pages of an existing PDF document into multiple individual PDF documents using Split method of PdfLoadedDocument class. The following code snippet explains the same.

//Due to platform limitations, Essential PDF supports splitting a PDF file into individual pages only in Windows Forms, WPF, ASP.NET, and ASP.NET MVC platforms. However this can be achieved by using the following code snippet. 

//Load the PDF document
FileStream docStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read);
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream);
for (int i=0;i<loadedDocument.PageCount;i++)
{
//Creates a new document
PdfDocument document = new PdfDocument();
//Imports the pages from the loaded document
document.ImportPage(loadedDocument, i);

Span a text element to multiple pages and draw the next element

The ‘PdfLayoutFormat’ class helps to allow the text to flow across pages. The ‘PdfLayoutResult’ class provides the rendered bounds of the previously added text, which can be used to place successive elements without overlapping.
The ‘Syncfusion PDF library’ provides ‘PageAddedEventArgs’ to get the current Page details, and we can draw the next new text element from where the last text element ends.
The following code example illustrates the same.

//Create a PDF document instance.
PdfDocument document = new PdfDocument();
//Add the event.
document.Pages.PageAdded += Pages_PageAdded;
//Create a new page and add it as the last page of the document.
PdfPage page = document.Pages.Add();
PdfGraphics graphics = page.Graphics;

//Read the long text from the text file.
FileStream inputStream = new FileStream("Input.txt", FileMode.Open, FileAccess.Read);
StreamReader reader = new StreamReader(inputStream, Encoding.ASCII);
string text = reader.ReadToEnd();
reader.Dispose();
const int paragraphGap = 10;
//Create a text element with the text and font.
PdfTextElement textElement = new PdfTextElement(text, new PdfStandardFont(PdfFontFamily.TimesRoman, 14));
PdfLayoutFormat layoutFormat = new PdfLayoutFormat();
layoutFormat.Layout = PdfLayoutType.Paginate;
layoutFormat.Break = PdfLayoutBreakType.FitPage;
//Draw the first paragraph.
PdfLayoutResult result = textElement.Draw(page, new RectangleF(0, 0, page.GetClientSize().Width / 2, page.GetClientSize().Height), layoutFormat);
//Draw the second paragraph from the first paragraph’s end position.
result = textElement.Draw(result.Page, new RectangleF(0, result.Bounds.Bottom + paragraphGap, page.GetClientSize().Width / 2, page.GetClientSize().Height), layoutFormat);

//Creating the stream object.
MemoryStream stream = new MemoryStream();
//Save the document into memory stream.
document.Save(stream);
//Close the document.
document.Close(true);

//Event handler for PageAdded event.
void Pages_PageAdded(object sender, PageAddedEventArgs args)
{
PdfPage page = args.Page;
page.Graphics.DrawRectangle(PdfPens.Black, new RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height));
}
//Create a new PDF document.
PdfDocument document = new PdfDocument();
//Add the event.
document.Pages.PageAdded += Pages_PageAdded;
//Create a new page and add it as the last page of the document.
PdfPage page = document.Pages.Add();
PdfGraphics graphics = page.Graphics;

//Read the long text from the text file.
StreamReader reader = new StreamReader(@"input.txt", Encoding.ASCII);
string text = reader.ReadToEnd();
reader.Close();
const int paragraphGap = 10;
//Create a text element with the text and font.
PdfTextElement textElement = new PdfTextElement(text, new PdfStandardFont(PdfFontFamily.TimesRoman, 14));
PdfLayoutFormat layoutFormat = new PdfLayoutFormat();
layoutFormat.Layout = PdfLayoutType.Paginate;
layoutFormat.Break = PdfLayoutBreakType.FitPage;

//Draw the second paragraph from the first paragraph’s end position.

//Save and close the document.
document.Save("Sample.pdf");
document.Close(true);

//Event handler for PageAdded event.
void Pages_PageAdded(object sender, PageAddedEventArgs args)
{
PdfPage page = args.Page;
page.Graphics.DrawRectangle(PdfPens.Black, new RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height));
}
'Create a new PDF document.
Dim document As New PdfDocument()
'Add the event.
AddHandler document.Pages.PageAdded, AddressOf Pages_PageAdded
'Create a new page and add it as the last page of the document.
Dim page As PdfPage = document.Pages.Add()
Dim graphics As PdfGraphics = page.Graphics

'Read the RTL text from the text file.

Inserting duplicate pages in the existing pdf document

The Syncfusion PDF library enables users to duplicate existing pages and insert them at various locations within a document. This functionality is especially valuable for creating templates, replicating forms, and expanding content without the need to manually recreate each page. The Insert method in the PdfLoadedPageCollection facilitates the creation of duplicate pages.

Refer to the following code example for creating duplicate page in a PDF document.

//Load the PDF document. 
FileStream docStream = new FileStream("Input.pdf", FileMode.Open, FileAccess.Read); 
PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream); 
//Gets the page 
PdfLoadedPage loadedPage= loadedDocument.Pages[0] as PdfLoadedPage; 
//Inserts the duplicate page in the beginning of the document. 
loadedDocument.Pages.Insert(0, loadedPage); 
//Creating the stream object. 
MemoryStream stream = new MemoryStream(); 
//Save the document as stream. 
loadedDocument.Save(stream); 
//Close the document. 
loadedDocument.Close(true);
//Load the PDF document. 
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf"); 
//Gets the Page 
PdfLoadedPage loadedPage= loadedDocument.Pages[0] as PdfLoadedPage; 
//Inserts the duplicate page in the beginning of the document. 
loadedDocument.Pages.Insert(0, loadedPage); 
//Save and close the document. 
loadedDocument.Save("Output.pdf"); 
//Close the document.
loadedDocument.Close(true);
'Load the PDF document. 
Dim loadedDocument As New PdfLoadedDocument("Input.pdf") 
'Gets the page. 
Dim page As PdfPageBase = TryCast(loadedDocument.Pages(0), PdfPageBase)  
'Inserts the duplicate page in the beginning of the document. 
loadedDocument.Pages.Insert(0, page) 
'Save and close the document. 
loadedDocument.Save("Output.pdf") 
'Close the document.
loadedDocument.Close(True)
