Applying License Key

To use IronPPT, apply a valid license or trial key by setting the LicenseKey property. Add the following code immediately after the import statement and before calling any IronPPT methods:

/// <summary>
/// This code sets the license key for the IronPPT library.
/// Ensure you have the correct namespace access by installing the IronPPT NuGet package
/// and adjust the license key appropriately for your use case.
/// </summary>

using System; // Required for Console output
using IronPPT; // Ensure the IronPPT library is referenced in your project.

namespace IronPPTApplication

    class Program
    {
        public static void Main(string[] args)
        {
            // Calling the method to set the IronPPT license key.
            SetIronPPTLicense();
        }

        /// <summary>

Code Examples

Let's explore some code examples and the features available.

Create PowerPoint File

Create the PowerPoint presentation by instantiating the PresentationDocument class using one of its constructors. Use the AddSlide and AddText methods to add slides and text, respectively. After that, use the Save method to export the PowerPoint presentation.

using IronPPT;

// This code demonstrates the creation of a PowerPoint presentation and saving it as a file.

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

// Create a new slide object
var slide = new Slide();

// Add text content to the slide
slide.AddText("Hello!");

// Add the newly created slide with text to the document
document.AddSlide(slide);

// Export the PowerPoint presentation to a file named "output.pptx"
document.Save("output.pptx");

using IronPPT;

// This code demonstrates the creation of a PowerPoint presentation and saving it as a file.

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

// Create a new slide object
var slide = new Slide();

// Add text content to the slide
slide.AddText("Hello!");

// Add the newly created slide with text to the document
document.AddSlide(slide);

// Export the PowerPoint presentation to a file named "output.pptx"
document.Save("output.pptx");

Imports IronPPT

' Create a new PowerPoint presentation document
Private document = New PresentationDocument()

' Create a new slide object
Private slide = New Slide()

' Add text content to the slide
slide.AddText("Hello!")

' Add the newly created slide with text to the document
document.AddSlide(slide)

' Export the PowerPoint presentation to a file named "output.pptx"
document.Save("output.pptx")

Imports IronPPT

slide.AddText("Hello!")

' Add the newly created slide with text to the document
document.AddSlide(slide)

' Export the PowerPoint presentation to a file named "output.pptx"
document.Save("output.pptx")

Add Shape

You can use the AddShape method from a slide object to add shapes. Various shape properties can be configured, such as fill color, outline color, position, angle, type, and more.

using IronPPT;
using IronPPT.Drawing; // Assuming this namespace contains `Shape` and `Color` classes
using IronPPT.Enums; // Assuming this namespace contains the `ShapeType` enum

// Load a PowerPoint presentation from the specified file
var document = new PresentationDocument("output.pptx");

// Create and configure a new shape, in this case, a triangle
Shape shape = new Shape
{
    Name = "triangle",             // Assign a name to the shape
    Type = ShapeType.Triangle,     // Set the shape type to Triangle
    Width = 100,                   // Set the width of the shape
    Height = 100,                  // Assumed height for the shape, should be set for visibility
    FillColor = new Color("#444444"), // Set the fill color of the shape
    OutlineColor = Color.Black,    // Set the outline color to black
    Position = new System.Drawing.Point(200, 200) // Set the position of the shape
};

// Ensure that the slides array has at least one slide to add the shape to
if (document.Slides.Count > 0)
{
    // Add the shape to the first slide
    document.Slides[0].AddShape(shape);
}
else
{
    // If there are no slides, handle the error or add a slide
    document.Slides.Add(new Slide()); // Assuming there's a way to add new slides
    document.Slides[0].AddShape(shape); // Add the shape to the newly added slide
}

// Export the PowerPoint presentation to a new file
document.Save("addShape.pptx");

using IronPPT;
using IronPPT.Drawing; // Assuming this namespace contains `Shape` and `Color` classes
using IronPPT.Enums; // Assuming this namespace contains the `ShapeType` enum

// Load a PowerPoint presentation from the specified file
var document = new PresentationDocument("output.pptx");

// Create and configure a new shape, in this case, a triangle
Shape shape = new Shape
{
    Name = "triangle",             // Assign a name to the shape
    Type = ShapeType.Triangle,     // Set the shape type to Triangle
    Width = 100,                   // Set the width of the shape
    Height = 100,                  // Assumed height for the shape, should be set for visibility
    FillColor = new Color("#444444"), // Set the fill color of the shape
    OutlineColor = Color.Black,    // Set the outline color to black
    Position = new System.Drawing.Point(200, 200) // Set the position of the shape
};

// Ensure that the slides array has at least one slide to add the shape to
if (document.Slides.Count > 0)
{
    // Add the shape to the first slide
    document.Slides[0].AddShape(shape);
}
else
{
    // If there are no slides, handle the error or add a slide
    document.Slides.Add(new Slide()); // Assuming there's a way to add new slides
    document.Slides[0].AddShape(shape); // Add the shape to the newly added slide
}

// Export the PowerPoint presentation to a new file
document.Save("addShape.pptx");

End If

' Export the PowerPoint presentation to a new file

Add Image

Adding an image to any slide is also a simple task. The code example below adds an image to the first slide, modifies the image's properties such as position, angle, name, width, and height, and then saves the updated presentation as a .pptx file.

using IronPPT;
using System.Drawing;

// This code demonstrates creating a new PowerPoint presentation, adding an image to it,
// modifying the image's properties, and exporting the presentation.

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

// Ensure there's at least one slide in the presentation
// Create the first slide if it doesn't exist yet
if (document.Slides.Count == 0)
{
    document.Slides.Add();
}

// Initialize an Image object
// Load an image from a file specified by the file path
// Ensure that "sample.png" exists at the specified path
Image image = new Image(); 
image.LoadFromFile("sample.png");

// Add the image to the first slide of the presentation
var newImage = document.Slides[0].AddImage(image);

// Edit the image's properties
// Set the position of the image using X and Y coordinates
newImage.Position = new Point(200, 200);

// Set the rotation angle of the image in degrees
newImage.Angle = 45;

// Set a name for the image, which can be useful for identification
newImage.Name = "new image";

// Set the dimensions of the image
newImage.Width = 150;
newImage.Height = 150;

// Export the PowerPoint presentation with the new image
document.Save("addImage.pptx");

using IronPPT;
using System.Drawing;

// This code demonstrates creating a new PowerPoint presentation, adding an image to it,
// modifying the image's properties, and exporting the presentation.

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

// Ensure there's at least one slide in the presentation
// Create the first slide if it doesn't exist yet
if (document.Slides.Count == 0)
{
    document.Slides.Add();
}

// Initialize an Image object
// Load an image from a file specified by the file path
// Ensure that "sample.png" exists at the specified path
Image image = new Image(); 
image.LoadFromFile("sample.png");

// Add the image to the first slide of the presentation
var newImage = document.Slides[0].AddImage(image);

// Edit the image's properties
// Set the position of the image using X and Y coordinates
newImage.Position = new Point(200, 200);

// Set the rotation angle of the image in degrees
newImage.Angle = 45;

// Set a name for the image, which can be useful for identification
newImage.Name = "new image";

// Set the dimensions of the image
newImage.Width = 150;
newImage.Height = 150;

// Export the PowerPoint presentation with the new image
document.Save("addImage.pptx");
