 Console.WriteLine(slide.GetAllText());

// Add a slide with a text box
using Unchained.Ooxml;

var newSlide = doc.Slides.AddBlank(layout);
newSlide.Shapes.AddTextBox(
 Emu.FromInches(1), Emu.FromInches(1),
 Emu.FromInches(8), Emu.FromInches(2),
 "Hello, Unchained!");

// Save
await processor.SaveAsync(doc, "output.pptx");
