Export Entire Presentation to Images

Call the Presentation.ExportToImages method to export presentation slides to images. This method returns an array of DXImage objects. Each array element in an exported slide.

The following code snippet exports all slides from a presentation as PNG images and saves them to a specified directory:

C#

using DevExpress.Docs.Presentation;
using DevExpress.Drawing;

namespace PresentationApiSample;

public class Program {
    public static async Task Main(string[] _) {

        // Load the presentation from a file
        Presentation presentation = new Presentation(File.ReadAllBytes(@"D:\presentation_to_export.pptx"));

        // Export all slides to images
        DXImage[] images = presentation.ExportToImages();

        // Create an output directory
        string outputDir = @"D:\presentation_as_images";
        Directory.CreateDirectory(outputDir);

        // Save each image to a file
        for (int i = 0; i < images.Length; i++) {
            images[i].Save(Path.Combine(outputDir, $"{i}.png"), DXImageFormat.Png);
        }
    }
}

VB.NET

Imports DevExpress.Docs.Presentation
Imports DevExpress.Drawing
Imports System.IO

Namespace PresentationApiSample

    Public Class Program
        Public Shared Async Function Main(ByVal _ As String()) As Task

            ' Load the presentation from a file
            Dim presentation As Presentation = New Presentation(File.ReadAllBytes("D:\presentation_to_export.pptx"))

            ' Export all slides to images
            Dim images As DXImage() = presentation.ExportToImages()

            ' Create an output directory
            Dim outputDir As String = "D:\presentation_as_images"
            Directory.CreateDirectory(outputDir)

            ' Save each image to a file
            For i As Integer = 0 To images.Length - 1
                images(i).Save(Path.Combine(outputDir, $"{i}.png"), DXImageFormat.Png)
            Next            
        End Function
    End Class
End Namespace

You can call the DXImage.Save method to save DXImage objects in different formats. The DXImageFormat class contains all supported image formats:

• BMP
• EMF
• GIF
• Icon
• JPEG
• PNG
• SVG
• TIFF
• WMF

Image Export Options

Pass ImageExportOptions to the Presentation.ExportToImages method to specify image export settings. You can specify the following options:

Rasterize

If set to false (default), slides are exported as vector images (EMF/SVG). If set to true, slides are exported as raster images (DXBitmap). If an image is rasterized, the Resolution option specifies the image size and the resolution value written to the image metadata.

Resolution

Specifies the resolution of exported raster images, in DPI. The default value is 96 DPI.

C#

using DevExpress.Docs.Presentation;
using DevExpress.Drawing;

    DXImage[] images = presentation.ExportToImages(new ImageExportOptions { Rasterize = true, Resolution = 300 });

VB.NET

Imports DevExpress.Docs.Presentation
Imports DevExpress.Drawing
Imports System.IO

    Dim images As DXImage() = presentation.ExportToImages(New ImageExportOptions With {.Rasterize = True, .Resolution = 300})

Export Specific Slides to Images

Pass an array of zero-based slide indexes to the Presentation.ExportToImages method to export specific slides from a presentation:

C#

using DevExpress.Docs.Presentation;
using DevExpress.Drawing;

    DXImage[] images = presentation.ExportToImages([0, 2]);

VB.NET

Imports DevExpress.Docs.Presentation
Imports DevExpress.Drawing
Imports System.IO

    Dim images As DXImage() = presentation.ExportToImages({0, 2})
