IronPPTは、.NET C#開発者がPowerPointプレゼンテーションを作成、読み込み、編集する機能をアプリケーションにシームレスに統合できるように設計された堅牢なPowerPointライブラリです。 PowerPointのプレゼンテーションでは、スライドはコンテンツを構成し、整理する基本的な要素です。

クイックスタート: 新規または既存のスライドにテキストを挿入する

この例では、IronPPTでいかに簡単にスライドにテキストを追加できるかを示しています。 わずか2、3行で、最初のスライドに挿入するか、スライドを作成し、保存します。

テキストコンテンツ

新しいプレゼンテーションを作成する場合でも、既存のプレゼンテーションを編集する場合でも、テキスト管理ツールを使用すると、テキストの配置や書式を完全に制御できるため、メッセージを明確かつプロフェッショナルに伝えるスライドをデザインできます。

using IronPPT;
using IronPPT.Models;

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

// Ensure there is at least one slide to work with
if (document.Slides.Count == 0)
{
    document.Slides.Add(new Slide());
}

// Add text to the first slide
var text = document.Slides[0].AddText("Hello");

// Append text to the existing text on the slide
text.Content += " There!";

// Check if there is any text element to remove from the first slide
if (document.Slides[0].Texts.Count > 0)
{
    document.Slides[0].Texts[0].Remove();
}

// Export the PowerPoint presentation with the specified file name

スタイル設定

テキストのスタイリングでは、フォントサイズ、色、スタイル、取り消し線、下線などの属性を定義することで、テキストの視覚的な外観をカスタマイズできます。これらのスタイルを適用することで、テキストの体裁を整え、文書全体の見栄えを向上させることができます。

: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
    SpecVanish = false,                // Text does not vanish when special formatting is applied
};

// 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
document.Slides[0].AddText(text);      // Add the newly created text object to the first slide

// Save the presentation document to a file
document.Save("textStyle.pptx");        // Save the document with the filename "textStyle.pptx"

// 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.

// 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.
