C#
//Create a new PDF document
PdfDocument doc = new PdfDocument();
//Load the image from the disk
PdfImage image = new PdfBitmap("Autumn Leaves.jpg");
for (int i = 0; i < 5; i++)
{
//Add a page to the document
PdfPage page = doc.Pages.Add();
//Create PDF graphics for the page
PdfGraphics graphics = page.Graphics;
//Draw an image
graphics.DrawImage(image, new RectangleF(0, 0, page.GetClientSize().Width, page.GetClientSize().Height));
}
//Save the document
doc.Save("Sample.pdf");
//Close the document
doc.Close(true); //This will open the PDF file so, the result will be seen in default PDF viewer System.Diagnostics.Process.Start("Sample.pdf");
VB.NET
