C# スライド要素チュートリアル – IronPPT
IronPPT は、.NET C# 開発者が PowerPoint プレゼンテーションの作成、読み取り、編集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強力な PowerPoint ライブラリです。 PowerPoint プレゼンテーションのコンテキストでは、スライドはコンテンツを構造化して整理する基本要素です。
クイックスタート: 新しいスライド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 を使用してスライドにテキストを簡単に追加できる方法を示します。 わずか数行で、最初のスライドがある場合はそこに挿入するか、新しいスライドを作成して保存します。セットアップが速く、手間が最小限です。

テキストを追加
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、テキストの配置と書式設定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。

テキストのスタイル設定では、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して、テキストの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、テキストの見栄えが向上し、ドキュメント全体の見栄えが向上します。
