行の改行を決定する

次のコードスニペットは、Aspose.PDF.Drawingライブラリでも機能します。

マルチラインTextFragmentの行の改行を追跡する

Aspose.PDF for .NETは、テキスト追加シナリオにおけるマルチラインテキストフラグメントの行の改行のバックグラウンド処理（トラッキング）を提供します。テキストフラグメントの行の改行を追跡するには、PageクラスのGetNotifications()メソッドを次のように使用できます。

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void DetermineLineBreak()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_Text();

    // Create PDF document
    using (var document = new Aspose.Pdf.Document())
    {
        // Enable notification logging
        document.EnableNotificationLogging = true;

        Aspose.Pdf.Page page = document.Pages.Add();

        for (int i = 0; i < 4; i++)
        {
            var text = new Aspose.Pdf.Text.TextFragment("Lorem ipsum \r\ndolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

            text.TextState.FontSize = 20;
            page.Paragraphs.Add(text);
        }

        // Save PDF document
        document.Save(dataDir + "DetermineLineBreak_out.pdf");

        string notifications = document.Pages[1].GetNotifications();
        File.WriteAllText(dataDir + "notifications_out.txt", notifications);
    }
}
