Syncfusion PowerPoint is a .NET Core PowerPoint library used to create, read, edit and convert PowerPoint presentation programmatically without Microsoft PowerPoint or interop dependencies. Using this library, you can convert a PowerPoint to image in .NET Core application on macOS.

Steps to convert PowerPoint to Image programmatically

Step 1: Create a new C# .NET Core console application.

Step 2: Select the project version.

Step 3: Install the Syncfusion.PresentationRenderer.Net.Core NuGet package as reference to your .NET Standard applications from NuGet.org.

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);
             }
         }
     }
 }
