Convert PowerPoint to Image using .NET Core and Latest

• Visual Studio
• Visual Studio Code
• JetBrains Rider

Step 1: Create a new .NET Core console application project.

Step 2: Install the Syncfusion.PresentationRenderer.Net.Core NuGet package as a reference to your project from NuGet.org.

1. If you’re deploying the application in a Linux environment, refer to the documentation for the required additional NuGet packages.
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.

C#

using Syncfusion.Presentation;
using Syncfusion.PresentationRenderer;

Step 4: Include the below code snippet in Program.cs to convert PowerPoint to image.

C#

//Open the existing PowerPoint presentation.
using (IPresentation pptxDoc = Presentation.Open("Data/Input.pptx"))
{
    //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(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);

Convert PowerPoint to Image in .NET Framework

• Visual Studio
• JetBrains Rider

Prerequisites:

• Visual Studio 2022.
• Install .NET desktop development workload with necessary .NET Framework SDK.

Step 1: Create a new .NET Framework console application project.

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

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.
