java - ICEpdf 查看器无法正确渲染字体

Question

我有一门课程可以在 JFrame 中使用 ICEpdf 6.2.2（maven 存储库中的最新版本）测试 ICEpdf 查看器。当我打开 PDF 时，我试图在 Ubuntu 的默认 PDF 查看器中呈现它，它显示正确，但是，当在 ICEpdf 查看器中显示时，字体间距错误，实际字体被替换为无衬线字体。这是我的ICEpdf 查看器和默认的 Ubuntu PDF 查看器中的GCC 手册的屏幕截图。我曾经收集手册中使用的字体是什么。在我的代码中，我设置为，这并没有解决问题。我的代码如下：pdffontsorg.icepdf.core.awtFontLoadingtrue

public class TestPDF {

    JFrame mainFrame;
    final Dimension SCREEN_SIZE = Toolkit.getDefaultToolkit().getScreenSize();

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    TestPDF window = new TestPDF();
                    window.mainFrame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    public TestPDF() {
        mainFrame = new JFrame();
        mainFrame.setTitle("Test");
        mainFrame.setSize(new Dimension((int) (SCREEN_SIZE.getWidth() / 2), (int) (SCREEN_SIZE.getHeight() / 2)));
        try {
             UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (ClassNotFoundException | InstantiationException | IllegalAccessException e) {
            e.printStackTrace();
        }
        PropertiesManager properties = new PropertiesManager(System.getProperties(), new Properties() {
            {
                setProperty("application.showLocalStorageDialogs", "false");
                setProperty("org.icepdf.core.awtFontLoading", "true");
            }
        }, ResourceBundle.getBundle(PropertiesManager.DEFAULT_MESSAGE_BUNDLE)) {
            {
                setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_ANNOTATION, Boolean.FALSE);
                setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_FORMS, Boolean.FALSE);
                setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_UTILITY, Boolean.FALSE);
                setBoolean(PropertiesManager.PROPERTY_SHOW_TOOLBAR_ROTATE, Boolean.FALSE);
            }
        };
        SwingController controller = new SwingController();
        SwingViewBuilder factory = new SwingViewBuilder(controller, properties);
        JPanel viewerComponentPanel = factory.buildViewerPanel();
        controller.getDocumentViewController().setAnnotationCallback(
                new org.icepdf.ri.common.MyAnnotationCallback(controller.getDocumentViewController()));

        try {
            File pdf = new File(this.getClass().getResource("/pdfTest/gcc.pdf").toURI());
            controller.openDocument(pdf.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
        mainFrame.add(viewerComponentPanel);
    }
}
