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.

Step 4: Include the following Namespaces in the Program.cs file.

C#

using Syncfusion.Presentation;
using Syncfusion.PresentationRenderer;

Step 5: Add the following code snippet in Program.cs file to convert a PowerPoint to image in .NET Core application on macOS.

C#

//Open the file as Stream.
 using (FileStream fileStreamInput = new FileStream("Data/Input.pptx", FileMode.Open, FileAccess.Read))
 {
     //Open the existing PowerPoint presentation with loaded stream.
     using (IPresentation pptxDoc = Presentation.Open(fileStreamInput))
     {
         //Initialize the PresentationRenderer to perform image conversion.
         pptxDoc.PresentationRenderer = new PresentationRenderer();
         //Convert PowerPoint slide to image as stream.
         using (Stream stream = pptxDoc.Slides[0].ConvertToImage(ExportImageFormat.Jpeg))
         {
             //Reset the stream position.
             stream.Position = 0;
             //Create FileStream to save the image file.
             using (FileStream outputStream = new FileStream("PPTXtoImage.Jpeg", FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
             {
                 //Save the image file.
                 stream.CopyTo(outputStream);
             }
         }
     }
