Syncfusion PowerPoint is a .NET 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 Windows Forms.

Steps to convert PowerPoint to Image programmatically

Step 1: Create a new C# Windows Forms application project.

Step 2: Install the Syncfusion.Presentation.WinForms 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 3: Include the following namespaces in the Form1.cs file.

C#

using Syncfusion.Presentation;

Step 4: Add a new button in Form1.Designer.cs file.

C#

private Button btnCreate;
private Label label;
private void InitializeComponent()
{
     label = new Label();
     btnCreate = new Button();
     //Label
     label.Location = new System.Drawing.Point(0, 40);
     label.Size = new System.Drawing.Size(426, 35);
     label.Text = "Click the button to Convert PowerPoint to Image.";
     label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;

     //Button
     btnCreate.Location = new System.Drawing.Point(180, 110);
     btnCreate.Size = new System.Drawing.Size(85, 36);
     btnCreate.Text = "Convert";
     btnCreate.Click += new EventHandler(btnConvert_Click);

     //Create PowerPoint
     ClientSize = new System.Drawing.Size(450, 150);
     Controls.Add(label);
     Controls.Add(btnCreate);
     Text = "Convert PowerPoint to Image";
}

Step 5: Add the following code in btnConvert_Click to convert a PowerPoint to image in Windows Forms.

C#

//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");
}
