2 Dec 20243 minutes to read

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);
}
