Question

我正在将.txt文件转换为.bmp（图片）。该.txt文件也可能包含不同语言的单词。当我使用java的BufferedImage转换它时，它会正确转换英文单词而不是其他语言的单词，图像显示其他语言单词的特殊字符。如何启用我的代码将.txt文件转换为.bmp（图像）？

我的.txt文件

**我的代码**

import java.awt.Color;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.image.BufferedImage;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import javax.imageio.ImageIO;

public class TextToGraphics {

    public static void main(String[] args) {
        try {
            int imgWid = 300;
            int imgHei = 300;

            String text = "Hello\nlklkj";
            String storeData = "";
            String data = "";
            File f = new File("/home/vipul/Desktop/123.txt");
            BufferedReader br = new BufferedReader(new FileReader(f));
            int nextLinePosition=100;
            int fontSize = 24;
            BufferedImage img = new BufferedImage(1, 1, BufferedImage.TYPE_3BYTE_BGR);
            Graphics2D g2d = img.createGraphics();
            Font font = new Font("Arial", Font.PLAIN, fontSize);
            g2d.setFont(font);

            FontMetrics fm = g2d.getFontMetrics();
            int width =imgWid;
            int height =imgHei;
            g2d.dispose();

            img = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR);
            g2d = img.createGraphics();
            g2d.setPaint(new Color(255, 255, 255));
            g2d.fillRect(0, 0, img.getWidth(), img.getHeight());
            System.out.println(img.getWidth() + " " + img.getHeight());
            g2d.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY);
            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            g2d.setRenderingHint(RenderingHints.KEY_COLOR_RENDERING, RenderingHints.VALUE_COLOR_RENDER_QUALITY);
            g2d.setRenderingHint(RenderingHints.KEY_DITHERING, RenderingHints.VALUE_DITHER_ENABLE);
            g2d.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS, RenderingHints.VALUE_FRACTIONALMETRICS_ON);
            g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
            g2d.setRenderingHint(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
            g2d.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
            g2d.setFont(font);
            fm = g2d.getFontMetrics();

            g2d.setColor(Color.BLACK);
            while ((data = br.readLine()) != null) {
                 g2d.drawString(data, 0, nextLinePosition);

                nextLinePosition=nextLinePosition+fontSize;

            } 
            g2d.dispose();

            ImageIO.write(img, "bmp", new File("/home/vipul/Desktop/123.bmp"));

        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }

}

是否有任何选项可以通过更改代码来打印图像中的不同语言单词，或者我必须启用任何字体支持？

请咨询。在此先感谢!!

您可能使用错误的编码读取了文件。

尝试替换

        Reader reader = new InputStreamReader(new FileInputStream("/home/vipul/Desktop/123.txt"), "utf-8");
        BufferedReader br = new BufferedReader(reader);

通过

LocalBroadcastManager

（或使用任何编码而不是utf-8）。
