GitHub - DevExpress-Examples/presentation-api-get-started: Creates a presentation with slides and saves it to PPTX and PDF. (original) (raw)

This example creates a new presentation, adds three slides, and populates slides with content.

Slide #1

Slide #2

Slide #3

Implementation Details

• Use the Presentation() parameterless constructor to create a new presentation.
  Presentation presentation = new Presentation();
• A newly created presentation contains a single default slide master. The Slide Master is a top-level template slide that you can use as a base for other slides. Slide masters store content, layouts and settings that you can share among derived slides. The default slide master goes first in the Presentation.SlideMasters collection.
  SlideMaster slideMaster = presentation.SlideMasters[0];
• To create a slide, initialize a Slide object and add it to the Presentation.Slides collection. For each slide, specify the layout type as a constructor parameter. In this example, slides use predefined layouts stored in the slide master. To obtain a layout from SlideMaster.Layouts, call the Get or GetOrCreate method.
  Slide slide1 = new Slide(slideMaster.Layouts.Get(SlideLayoutType.Title));
  //...
  presentation.Slides.Add(slide1);
• Layouts add placeholder shapes to slides. Use the Slide.Shapes collection to access placeholder shapes and populate them with content.
  foreach (Shape shape in slide1.Shapes) {
  if (shape.PlaceholderSettings.Type is PlaceholderType.CenteredTitle) {
  shape.TextArea = new TextArea("Daily Testing Status Report");
  }
  if (shape.PlaceholderSettings.Type is PlaceholderType.Subtitle) {
  shape.TextArea = new TextArea($"{DateTime.Now: dddd, MMMM d, yyyy}");
  }
  }
• You can save the resulting presentation to a PPTX file and export it to a PDF file:
  FileStream outputStream = new FileStream(@"......\data\my-presentation.pptx", FileMode.Create);
  presentation.SaveDocument(outputStream);
  outputStream.Dispose();
  presentation.ExportToPdf(new FileStream(@"......\data\exported-document.pdf", FileMode.Create));
