C#/VB.NET: Convert ODP to PDF

An ODP file is an OpenDocument Presentation file consisting of slides containing images, text, media, and transition effects. Since ODP files can only be opened by specified programs such as OpenOffice Impress, LibreOffice Impress, and Microsoft PowerPoint, if you want your ODP files to be viewable on more devices, you can convert them to PDF. In this article, you will learn how to programmatically convert a ODP file to PDF using Spire.Presentation for .NET.

Install Spire.Presentation for .NET

To begin with, you need to add the DLL files included in the Spire.Presentation for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

PM> Install-Package Spire.Presentation

Convert OpenDocument Presentation to PDF

The detailed steps are as follows:

• Create a Presentation instance.
• Load an ODP file using Presentation.LoadFromFile() method.
• Save the ODP file to PDF using Presentation.SaveToFile(String, FileFormat) method.

using Spire.Presentation;

namespace ODPtoPDF
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a Presentation instance
            Presentation presentation = new Presentation();

            //Load an ODP file
            presentation.LoadFromFile("Sample.odp", FileFormat.ODP);

            //Convert the ODP file to PDF
            presentation.SaveToFile("OdptoPDF.pdf", FileFormat.PDF);

        }
    }
}

Imports Spire.Presentation

Namespace ODPtoPDF
    Class Program
        Private Shared Sub Main(ByVal args As String())

            'Create a Presentation instance
            Dim presentation As Presentation = New Presentation()

            'Load an ODP file
            presentation.LoadFromFile("Sample.odp", FileFormat.ODP)

            'Convert the ODP file to PDF
            presentation.SaveToFile("OdptoPDF.pdf", FileFormat.PDF)
        End Sub
    End Class
End Namespace
