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");
}
