Determine Line Break

The following code snippet also work with Aspose.PDF.Drawing library.

Track Line Breaking of Multi-Line TextFragment

Aspose.PDF for .NET offers logging (tracking) background processing (line breaking) of multi-line text fragments in text adding scenarios. You can use the GetNotifications() method of Page class as follows, in order to track line breaking of text fragment:

.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.

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);
