How to merge multiple TIFF images to a single PDF using C# and VB.NET?
Syncfusion Essential® PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can merge multiple TIFF images to a single PDF using C# and VB.NET.
Steps to merge multiple TIFF images to a single PDF programmatically:
- Create a new C# console application project.
- Install the Syncfusion.Pdf.WinForms NuGet package as reference to your .NET Framework application from NuGet.org.
- Use the following namespaces in the Program.cs file.
C#
using Syncfusion.Pdf; using Syncfusion.Pdf.Graphics; using System.Drawing; using System.IO;
VB.NET
Imports Syncfusion.Pdf Imports Syncfusion.Pdf.Graphics Imports System.Drawing Imports System.IO
- Use the following code snippet to merge multiple TIFF images to a single PDF.
C#
//Create a new PDF document
PdfDocument document = new PdfDocument();
//Get the directory information
DirectoryInfo directory = new DirectoryInfo(path);
FileInfo[] fileInfo = directory.GetFiles("*.tif*");
foreach (FileInfo file in fileInfo)
{
//Load the image
PdfBitmap image = new PdfBitmap(file.FullName);
//Add a page to the document
PdfPage page = document.Pages.Add();
//Draw the image
page.Graphics.DrawImage(image,new PointF(0,0), new SizeF(page.GetClientSize().Width,page.GetClientSize().Height));
}
//Save the document
document.Save("Sample.pdf");
//Close the document
document.Close(true);
//This will open the PDF file so, the result will be seen in default PDF viewer
Process.Start("Sample.pdf");
VB.NET
'Create a new PDF document
Dim document As PdfDocument = New PdfDocument()
'Get the directory information
Dim directory As DirectoryInfo = New DirectoryInfo(path)
Dim fileInfo As FileInfo() = directory.GetFiles("*.tif*")
For Each file As FileInfo In fileInfo
'Load the image
Dim image As PdfBitmap = New PdfBitmap(file.FullName)
'Add a page to the document
Dim page As PdfPage = document.Pages.Add()
'Draw the image
page.Graphics.DrawImage(image, New PointF(0, 0), New SizeF(page.GetClientSize().Width, page.GetClientSize().Height))
Next
'Save the document
document.Save("Sample.pdf")
'Close the document
document.Close(True)
'This will open the PDF file so, the result will be seen in default PDF viewer
Process.Start("Sample.pdf")
