确定 TextFragment 中的换行符

跟踪多行 TextFragment 的换行

Aspose.PDF for C++ 提供了在文本添加场景中对多行文本片段的后台处理（换行）的记录（跟踪）。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：

using namespace System;
using namespace Aspose::Pdf;
using namespace Aspose::Pdf::Text;

void LineBreakDemo() {

    String _dataDir("C:\\Samples\\");

    auto document = MakeObject<Document>();
    auto page = document->get_Pages()->Add();

    for (int i = 0; i < 4; i++)
    {
        auto text = MakeObject<TextFragment>(u"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->get_TextState()->set_FontSize(20);
        page->get_Paragraphs()->Add(text);
    }

    document->Save(_dataDir + u"DetermineLineBreak_out.pdf");

    String notifications = page->GetNotifications();
    Console::WriteLine(notifications);
    System::IO::File::WriteAllText(_dataDir + u"notifications_out.txt",notifications);
}
