NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

    //Open the existing PowerPoint presentation.
    using (IPresentation pptxDoc = Presentation.Open(fileStream))
    {
        //Initialize the PresentationRenderer to perform image conversion.
        pptxDoc.PresentationRenderer = new PresentationRenderer();
        //Convert PowerPoint slide to image as stream.
        Stream stream = pptxDoc.Slides[0].ConvertToImage(Syncfusion.Presentation.ExportImageFormat.Jpeg);
        //Reset the stream position.
        stream.Position = 0;
        //Create the output image file stream.
        using (FileStream fileStreamOutput = File.Create(Path.GetFullPath("Data/PPTXToImage.jpeg")))
        {
            //Copy the converted image stream into created output stream.
            stream.CopyTo(fileStreamOutput);

Step 2: Install Syncfusion.Presentation.WinForms NuGet package as a reference to your Windows Forms application from the NuGet.org.

Install Syncfusion.Presentation.WinForms NuGet package

NOTE

  1. The Syncfusion.Presentation.WinForms is a dependency for Syncfusion Windows Forms GUI controls and is named with the suffix “WinForms”. It contains platform-independent .NET Framework assemblies (compatible with versions 4.0, 4.5, 4.5.1, and 4.6) for the PowerPoint library and does not include any Windows Forms-related references or code. Therefore, we recommend using this package for .NET Framework Console applications.
  2. Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 3: Include the following namespaces in Program.cs file.

using Syncfusion.Presentation;

//Open an existing PowerPoint Presentation.
using (IPresentation pptxDoc = Presentation.Open("Data/Input.pptx"))
{
    //Convert the first slide into image.
    Image image = pptxDoc.Slides[0].ConvertToImage(Syncfusion.Drawing.ImageType.Metafile);
    //Save the image file.
    image.Save("PPTXtoImage.Jpeg");
}
