Write text onto image in Java
提问by n002213f
Is there a Java library to write text to images, same as PHP's GD library.
是否有一个 Java 库可以将文本写入图像，与 PHP 的GD 库相同。

Sure. First load the image, probably using a method of ImageIO. Then, using a Graphicsobject representing the image itself, call the drawStringmethod.
当然。首先加载图像，可能使用ImageIO. 然后，使用Graphics表示图像本身的对象，调用该drawString方法。

Try the below code
试试下面的代码
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
public class Testing {
public static void main(String arg[]) throws IOException {
String key = "Sample";
BufferedImage bufferedImage = new BufferedImage(170, 30,
BufferedImage.TYPE_INT_RGB);
Graphics graphics = bufferedImage.getGraphics();
graphics.setColor(Color.LIGHT_GRAY);
graphics.fillRect(0, 0, 200, 50);
graphics.setColor(Color.BLACK);
graphics.setFont(new Font("Arial Black", Font.BOLD, 20));
graphics.drawString(key, 10, 25);
ImageIO.write(bufferedImage, "jpg", new File(
"C:/Users/admin/desktop/image.jpg"));
System.out.println("Image Created");
}
}
