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:

// For complete examples and data files, please go to https://github.com/aspose-pdf/Aspose.PDF-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_AsposePdf_Text();

Document document = new Document();
Page page = document.Pages.Add();

for (int i = 0; i < 4; i++)
{
    TextFragment text = new 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);
}
document.Save(dataDir + "DetermineLineBreak_out.pdf");

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