OpenJDK has bug on DBCS fonts’ support: it can’t support to render text with rotation for the fonts like: MingLiu, HeiT, MS PGothic, MS PMincho, Batang and Gulim.

Because I am not able to enter bug in the offical OpenJDK website, I am entering bug here to see if you could help to help to redirect this problem to a proper guy to handle it. Thanks a lot!

Below is the sample code to reproduce the problem:

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;

import javax.imageio.ImageIO;

public class TestFontRender {

private static final String IMAGE_TYPE="png";
// You may need to change the filepath below in order to save the image in proper path.
private static final String IMAGE_FILEPATH="c:\fontRender_openjdk.png";

/**
 * @param args
 */
public static void main(String[] args) {

    TestFontRender code = new TestFontRender();
    BufferedImage bufferImage = code.getImage();
    code.saveImage(bufferImage, IMAGE_TYPE, IMAGE_FILEPATH);
}

public BufferedImage getImage() {
    int width = 800;
    int height = 600;
    int degree = -90;
    BufferedImage image = new BufferedImage(width, height,
            BufferedImage.TYPE_INT_RGB);

    Graphics g = image.getGraphics();

    Color background = new Color(255, 255, 255);
    g.setColor(background);
    g.fillRect(0, 0, width, height);

    g.setColor(getColor());
    g.drawRect(0, 0, width - 1, height - 1);

    Color textColor = new Color(255, 0, 0);
    g.setColor(textColor);

    //"MS PGothic" font
    String text = "Height (日本平均)アイウ MS PGothic angle=0";
    Font textFont = new Font("MS PGothic",Font.PLAIN,14);
    g.setFont(textFont);
    Graphics2D g2d_1 = (Graphics2D) g.create();
    g2d_1.translate(20, 20);
    g2d_1.drawString(text, 0, 0);

    g2d_1.translate(20, 300);
    g2d_1.rotate(degree * Math.PI / 180);
    text = "Height (日本平均)アイウ MS PGothic angle=-90";
    g2d_1.drawString(text, 0, 0);

    //"MS PMincho" font
    text = "Height (日本平均)アイウ MS PMincho angle=0";
    textFont = new Font("MS PMincho",Font.PLAIN,14);
    g.setFont(textFont);
    Graphics2D g2d_2 = (Graphics2D) g.create();
    g2d_2.translate(85, 55);
    g2d_2.drawString(text, 0, 0);

    g2d_2.translate(55, 300);
    g2d_2.rotate(degree * Math.PI / 180);
    text = "Height (日本平均)アイウ MS PMincho angle=-90";
    g2d_2.drawString(text, 0, 0);


    //"Gulim" font
    text = "Height (Korea) Gulim angle=0";
    textFont = new Font("Gulim",Font.PLAIN,14);
    g.setFont(textFont);
    Graphics2D g2d_3 = (Graphics2D) g.create();
    g2d_3.translate(145, 85);
    g2d_3.drawString(text, 0, 0);

    g2d_3.translate(85, 300);
    g2d_3.rotate(degree * Math.PI / 180);
    text = "Height (Korea) Gulim angle=-90";
    g2d_3.drawString(text, 0, 0);


    //"HeiT" font
    text = "Height (平均) HeiT angle=0";
    textFont = new Font("HeiT",Font.PLAIN,14);
    g.setFont(textFont);
    Graphics2D g2d_4 = (Graphics2D) g.create();
    g2d_4.translate(200, 115);
    g2d_4.drawString(text, 0, 0);

    g2d_4.translate(115, 300);
    g2d_4.rotate(degree * Math.PI / 180);
    text = "Height (平均) HeiT angle=-90";
    g2d_4.drawString(text, 0, 0);


    g.dispose();
    return image;
}

private Color getColor() {
    int R = (int) (Math.random() * 255);
    int G = (int) (Math.random() * 255);
    int B = (int) (Math.random() * 255);
    return new Color(R, G, B);
}

public void saveImage(BufferedImage image, String format, String filePath) {
    try {
        ImageIO.write(image, format, new File(filePath));
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}
