Question

我编写了一个打印JFrame内容的Java程序。它在框架中的标签中与英语完美配合，但当我在其中使用马拉雅拉姆语unicode字符串时出错。

import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Frame; 
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.print.PageFormat;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.awt.print.PrinterJob;
import javax.swing.JLabel;

public class MalayalamPrintingSSCCE {

private static Frame frame;

public static void main(String[] args) {

    frame = new Frame();
    frame.setLayout(new FlowLayout());
    frame.add(new JLabel("Vishnu1"));
    frame.add(new JLabel("\u0D35\u0D3F\u0D37\u0D4D\u0D23\u0D41"));//വിഷ്ണു
    frame.add(new JLabel("\u0D35\u0D3F\u0D37\u0D4D\u0D23\u0D41"));//വിഷ്ണു
    frame.add(new JLabel("\u0D35\u0D3F\u0D37\u0D4D\u0D23\u0D41"));//വിഷ്ണു
    frame.add(new JLabel("Vishnu4"));
    frame.setVisible(true);
    frame.pack();

    PrinterJob pj = PrinterJob.getPrinterJob();
    pj.setJobName(" Print Component ");

    pj.setPrintable(new Printable() {
        public int print(Graphics pg, PageFormat pf, int pageNum) {
            if (pageNum > 0) {
                return Printable.NO_SUCH_PAGE;
            }
            Dimension dim = frame.getSize();
            double cHeight = dim.getHeight();
            double cWidth = dim.getWidth();

            // get the bounds of the printable area
            double pHeight = pf.getImageableHeight();
            double pWidth = pf.getImageableWidth();

            double pXStart = pf.getImageableX();
            double pYStart = pf.getImageableY();

            double xRatio = pWidth / cWidth;
            double yRatio = pHeight / cHeight;

            Graphics2D g2 = (Graphics2D) pg;
            g2.translate(pXStart, pYStart);
            g2.scale(xRatio, xRatio);
            frame.paint(g2);
            return Printable.PAGE_EXISTS;
            }
        });

        try {
            if (pj.printDialog()) {
                    pj.print();
                }
            } catch (PrinterException ex) {
            // handle exception
            }
        }
    }

英文打印机输出： Print output with english 使用马拉雅拉姆语输出打印机 print output with malayalam 但是，框架渲染正确如下： enter image description here 我怎样才能解决这个问题？有没有更好的方法呢？

Answer 1

您可以将font添加到label，然后在Frame

上打印马拉雅拉姆语

以下显示了一个在malayalam中打印我姓名的简单代码：

import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JLabel;

    /**
     * @author Rakesh KR
     */

public class SimpleGUI1 {



    public static void main(String[] args) {
        SimpleGUI1 gUI = new SimpleGUI1();
        gUI.action();
    }

    void action(){
        JFrame  frame  = new JFrame();
        JLabel label = new JLabel("രാകേഷ്");
        // Can also use unicode 
        //JLabel label= new JLabel("\u0d30\u0d3e\u0d15\u0d47\u0d37\u0d4d");
        Font font = new Font("Arial Unicode MS", Font.PLAIN, 12);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        label.setFont(font);
        frame.add(label);
        frame.setSize(100,100);
        frame.setVisible(true);

    }


}

输出

修改

通过使用上面frame（添加的字体），我们还可以打印马拉雅拉姆语。

import java.awt.Font; import javax.swing.JFrame; import javax.swing.JLabel; /** * @author Rakesh KR */ public class SimpleGUI1 { public static void main(String[] args) { SimpleGUI1 gUI = new SimpleGUI1(); gUI.action(); } void action(){ JFrame frame = new JFrame(); JLabel label = new JLabel("രാകേഷ്"); // Can also use unicode //JLabel label= new JLabel("\u0d30\u0d3e\u0d15\u0d47\u0d37\u0d4d"); Font font = new Font("Arial Unicode MS", Font.PLAIN, 12); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); label.setFont(font); frame.add(label); frame.setSize(100,100); frame.setVisible(true); PrinterJob pj = PrinterJob.getPrinterJob(); pj.setJobName(" Print Component "); pj.setPrintable(new Printable() { public int print(Graphics pg, PageFormat pf, int pageNum) { if (pageNum > 0) { return Printable.NO_SUCH_PAGE; } Dimension dim = frame.getSize(); double cHeight = dim.getHeight(); double cWidth = dim.getWidth(); // get the bounds of the printable area double pHeight = pf.getImageableHeight(); double pWidth = pf.getImageableWidth(); double pXStart = pf.getImageableX(); double pYStart = pf.getImageableY(); double xRatio = pWidth / cWidth; double yRatio = pHeight / cHeight; Graphics2D g2 = (Graphics2D) pg; g2.translate(pXStart, pYStart); g2.scale(xRatio, xRatio); frame.paint(g2); return Printable.PAGE_EXISTS; } }); try { if (pj.printDialog()) { pj.print(); } } catch (PrinterException ex) { } } } }

输出： Pdf保存打印页面的格式
单个标签上的
编辑 结果还可以。但是有两种语言的多个标签，就会发生错误 为此，您需要在JPanel中添加JFrame，然后在JPanel添加所需的组件，例如JLabel。

final JFrame frame = new JFrame(); JPanel panel = new JPanel(); JLabel label = new JLabel("രാകേഷ്"); JLabel label1 = new JLabel("Rakesh"); JLabel label2 = new JLabel("\u0d30\u0d3e\u0d15\u0d47\u0d37\u0d4d"); JLabel label3 = new JLabel("Rakesh"); Font font = new Font("Arial Unicode MS", Font.PLAIN, 12); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); label.setFont(font); label1.setFont(font); label2.setFont(font); label3.setFont(font); panel.add(label); panel.add(label1); panel.add(label2); panel.add(label3); frame.add(panel); frame.setSize(300,300); frame.setVisible(true); frame.pack();

输出：

JFrame：打印不使用malayalam文本
