DevExpress PowerPoint Presentation API

The DevExpress Presentation API is a cross-platform .NET library that allows you to manage Microsoft PowerPoint presentation files. Use available APIs to create, edit, read, merge, split, print, export, and digitally sign presentations. All this functionality is available in your .NET applications without Microsoft Office dependencies.

Code Example - Create a New Presentation from Scratch

using DevExpress.Docs.Presentation;
//...
// Create a presentation with a single empty slide
Presentation presentation = new Presentation();
// Configure Slide Master
SlideMaster slideMaster = presentation.SlideMasters[0];
slideMaster.Background = new CustomSlideBackground(new SolidFill(Color.FromArgb(194, 228, 249)));

// Add a new slide with content
presentation.Slides.Clear();
Slide slide1 = new Slide(slideMaster.Layouts.Get(SlideLayoutType.Title));
foreach (Shape shape in slide1.Shapes) {
    if (shape.Placeholder.Type is PlaceholderType.CenteredTitle) {
        TextArea textArea = new TextArea();
        TextParagraph paragraph = new TextParagraph();
        paragraph.Runs.Add(new TextRun { Text = "Daily Testing Status Report" });
        textArea.Paragraphs.Add(paragraph);
        shape.TextArea = textArea;
    }
    if (shape.Placeholder.Type is PlaceholderType.Subtitle) {
        TextArea textArea = new TextArea();
        TextParagraph paragraph = new TextParagraph();
        paragraph.Runs.Add(new TextRun { Text = $"{DateTime.Now: dddd, MMMM d, yyyy}" });
        textArea.Paragraphs.Add(paragraph);
        shape.TextArea = textArea;
    }
}
