IronPPT est une bibliothèque PowerPoint robuste conçue pour aider les développeurs .NET C# à intégrer de manière transparente la possibilité de créer, lire et modifier des présentations PowerPoint dans leurs applications. Dans le contexte d'une présentation PowerPoint, les diapositives sont les éléments fondamentaux qui structurent et organisent le contenu.

Quickstart : Insérer du texte dans une nouvelle diapositive ou une diapositive existante

Cet exemple montre comment vous pouvez ajouter du texte à une diapositive sans effort avec IronPPT. En quelques lignes seulement, insérez dans la première diapositive si elle existe ou créez-en une, puis enregistrez.

Install IronPPT with NuGet Package Manager

PM > Install-Package IronPPT

Copy and run this code snippet.

var doc = new IronPPT.PresentationDocument();
var text = doc.Slides.Count > 0 ? doc.Slides[0].AddText("Quick Option") : doc.Slides.Add(new IronPPT.Models.Slide()).AddText("Quick Option");
doc.Save("quick.pptx");

Set Styling

La mise en forme du texte permet de personnaliser son apparence visuelle en définissant des attributs tels que la taille de la police, la couleur, le style, le barré et le souligné. L'application de ces styles améliore la présentation du texte et l'aspect général du document.

:path=/static-assets/ppt/content-code-examples/tutorials/slide-element-text-style.cs

using IronPPT;
using IronPPT.Models; // Ensure the library is available

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

// Define and customize the text style
var textStyle = new TextStyle
{
    IsBold = true,                      // Text is bold
    IsItalic = true,                    // Text is italic
    Color = Color.Blue,                 // Text color is blue
    Strike = StrikeValue.SingleStrike,  // Text is single struck-off
    Outline = true,                     // Text has an outline
    NoProof = true,                     // Disables proofing for the text
    Spacing = 10.0,                     // Text spacing is set to 10
    Underline = new Underline 
    {
        LineValue = UnderlineValues.Single,   // Single underline
        Color = Color.Red                     // Underline color is red
    },
    Languages = "en-US",               // Text language is set to U.S. English

};

// Create text content and apply the defined style
var text = new Text("Hello World");   // Instantiate text with a string
text.TextStyle = textStyle;           // Apply the defined style to the text

// Add a new slide if none exist
if (document.Slides.Count == 0)
{
    document.Slides.Add(new Slide());   // Add a new slide to the document
}

// Add the styled text to the first slide

Ajouter des images

Ajustez les paramètres de l'image pour un affichage optimal. Une configuration adéquate permet de s'assurer que les images sont visuellement attrayantes et adaptées à leur contexte.

using IronPPT;

using System.Drawing;

// This script demonstrates the creation of a PowerPoint presentation using the IronPPT library.
// An image is added to the presentation, its properties are modified, and then the presentation is saved.

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

// Create a new Image object and load an image file.
var image = new Image();
image.LoadFromFile("sample.png");

// Add the image to the first slide (index 0) of the presentation.
var newImage = document.AddImage(image, 0);

// Set the properties of the added image.
// Position property is set using a Point object, which holds X and Y coordinates.
newImage.Position = new Point(200, 200); // Set image position on the slide
newImage.Angle = 45; // Set the rotation angle of the image
newImage.Name = "new image"; // Assign a descriptive name to the image
newImage.Width = 150; // Set the width of the image in pixels
newImage.Height = 150; // Set the height of the image in pixels

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

Ajouter des formes

Ajoutez et personnalisez facilement des formes dans votre présentation en définissant leur type, leurs dimensions (largeur et hauteur), leurs couleurs de remplissage et de contour, ainsi que leur position sur la diapositive.

:path=/static-assets/ppt/content-code-examples/tutorials/slide-element-add-shape.cs

using IronPPT;
using IronPPT.Models;
using IronPPT.Enums;

// Load a PowerPoint presentation.
// The PresentationDocument is assumed to represent an entire PPTX file loaded from disk.
var document = new PresentationDocument("output.pptx");

// Configure a new shape.
// Shape is assumed to be a model object representing drawable elements on a slide.
Shape shape = new Shape
{
    Name = "triangle",
    Type = ShapeType.Triangle,
    Width = 100,
    FillColor = new Color("#444444"),
    OutlineColor = Color.Black,

    // Position is set via assumed X and Y positioning properties.
    // It's important that these properties are set to valid coordinates for display on the slide.
    XPosition = 200,
    YPosition = 200
};

// Add the shape to the first slide in the presentation.
// Slides[0] refers to the first slide in the collection. Ensure a slide exists at this index.
document.Slides[0].AddShape(shape);

// Export the modified PowerPoint presentation.
// Saves the changes to a new file, ensuring the original presentation is not overwritten.
document.Save("addShape.pptx");
