跟踪多行 TextFragment 的换行

Aspose.PDF for .NET 提供了多行文本片段在文本添加场景中的日志（跟踪）后台处理（换行）。您可以使用 Page 类的 GetNotifications() 方法，如下所示，以跟踪文本片段的换行：

.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. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.");
            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);
    }
}

.NET 8

// 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.

        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);
}
