Step 3: Add a new button in the MainWindow.xaml as shown below.

<Window x:Class="Convert_PowerPoint_Presentation_to_Image.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:Convert_PowerPoint_Presentation_to_Image"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button Click="btnConvert_Click" VerticalAlignment="Center" Height="19" BorderBrush="LightBlue" HorizontalAlignment="Center" Width="130">
            <Button.Background>
                <LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
                    <GradientStop Color="#FFD9E9F7" Offset="0"/>
                    <GradientStop Color="#FFEFF8FF" Offset="1"/>
                </LinearGradientBrush>
            </Button.Background>
            <StackPanel Orientation="Horizontal" Height="20" VerticalAlignment="Center" HorizontalAlignment="Left" Width="150">
                <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
                <TextBlock Text="Convert PPTX to Image" Height="19" Width="125" />
            </StackPanel>
        </Button>
    </Grid>
</Window>

Step 4: Include the following namespaces in the MainWindow.xaml.cs file.

using Syncfusion.Presentation;

Step 5: Add the following code in btnConvert_Click to convert PowerPoint to image in WPF.

//Open a PowerPoint Presentation.
using (IPresentation pptxDoc = Presentation.Open("Data/Input.pptx"))
{
    //Converts the first slide into image.
    System.Drawing.Image image = pptxDoc.Slides[0].ConvertToImage(Syncfusion.Drawing.ImageType.Metafile);
    //Save the image as jpeg.
    image.Save("PPTXtoImage.Jpeg");
}
