Syncfusion PowerPoint is a UWP 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 UWP.

Steps to convert PowerPoint to Image programmatically

Step 1: Create a new C# UWP application project.

Step 2: Install the Syncfusion.Presentation.UWP 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: Add a new button in the MainPage.xaml as shown below.

C#

<Page
    x:Class="Convert_PowerPoint_Presentation_to_Image.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Convert_PowerPoint_Presentation_to_Image"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid>
        <Button x:Name="button" Content="Convert PPTX to Image" Click="OnButtonClicked" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
</Page>

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

C#

using Syncfusion.OfficeChartToImageConverter;

Step 5: Include the below code snippet in the click event of the button in MainPage.xaml.cs to convert the PowerPoint to image in UWP.

C#

//Load the presentation file using open picker.
FileOpenPicker openPicker = new FileOpenPicker();
openPicker.FileTypeFilter.Add(".pptx");
StorageFile inputFile = await openPicker.PickSingleFileAsync();
using (IPresentation pptxDoc = await Presentation.OpenAsync(inputFile))
{
    //Initialize the ‘ChartToImageConverter’ instance to convert the charts in the slides.
    pptxDoc.ChartToImageConverter = new ChartToImageConverter();
    //Pick the folder to save the converted images.
    FolderPicker folderPicker = new FolderPicker
    {
        ViewMode = PickerViewMode.Thumbnail
    };
    folderPicker.FileTypeFilter.Add("*");
    StorageFolder storageFolder = await folderPicker.PickSingleFolderAsync();
    StorageFile imageFile = await storageFolder.CreateFileAsync("PPTXtoImage.jpg", CreationCollisionOption.ReplaceExisting);
    ISlide slide = pptxDoc.Slides[0];
    //Convert the PPTX to image.
    await slide.SaveAsImageAsync(imageFile);
}
