IronPPT.Examples

Runnable C# examples for IronPPT, a .NET library for creating, reading, and editing PPTX presentations without Microsoft PowerPoint or Office Interop.

Install

dotnet add package IronPPT

Quickstart

using IronPPT;
using IronPPT.Models;

// Create a new presentation
var document = new PresentationDocument();

// Add a slide with text
var slide = new Slide();
slide.AddText("Hello from IronPPT!");
document.AddSlide(slide);

document.Save("hello.pptx");

To edit an existing deck, use new PresentationDocument("existing.pptx") and access slides through the Slides collection — for example, document.Slides[0].TextBoxes[0].AddText("Updated title"). Images, shapes, and styled paragraphs follow the same pattern: construct, configure, add to a slide.

For production use, set a license key via License.LicenseKey = "YOUR-KEY". Without one, presentations include a watermark.

What's in this repo

Each folder contains a self-contained .NET project you can open and run:

• examples/ — focused snippets demonstrating individual features
• get-started/ — minimal first projects including license-key setup
• how-to/ — task-oriented guides for specific presentation operations
• quickstart/ — end-to-end project scaffolds
• tutorials/ — longer walkthroughs (including the slide-element tutorial covering text boxes, paragraphs, images, and shapes)

Common tasks covered

• Creating and loading PPTX files
• Adding slides, text boxes, and styled paragraphs
• Text styling: font family, size, color, bold, italic, underline, alignment
• Inserting images with positioning, scaling, and sizing
• Adding shapes with fill color, outline, rotation, and shape type (rectangle, triangle, ellipse, cloud, and more)
• Slide layout: size, orientation, background color
• Reading text and structural content from existing decks
• Bullet and numbered lists with custom indentation

Current scope

IronPPT supports programmatic creation and editing of .pptx files. Rendering presentations to PDF or images, and slideshow playback, are not currently supported — for PDF output from a presentation, generate the PPTX with IronPPT and convert it separately.

Platform support

.NET 10, 9, 8, 7, 6, 5, .NET Core 3.1, .NET Standard 2 and 2.1, and .NET Framework 4.6.2+. Windows, macOS, Linux, Docker, Azure, and AWS. See the installation docs for environment-specific notes.
