import java.awt.Color;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
public class ConvertImageFile {
public static void main(String[] args) {
BufferedImage bufferedImage;
try {
// read image file
bufferedImage = ImageIO.read( new File( "c:\\java.png" ));
// create a blank, RGB, same width and height, and a white
// background
BufferedImage newBufferedImage = new BufferedImage(
bufferedImage.getWidth(), bufferedImage.getHeight(),
BufferedImage.TYPE_INT_RGB);
// TYPE_INT_RGB:创建一个RBG图像,24位深度,成功将32位图转化成24位
newBufferedImage.createGraphics().drawImage(bufferedImage, 0 , 0 ,
Color.WHITE, null );
// write to jpeg file
ImageIO.write(newBufferedImage, "jpg" , new File( "c:\\java.jpg" ));
System.out.println( "Done" );
} catch (IOException e) {
e.printStackTrace();
}
}
}

希望本文所述对大家java程序设计有所帮助。
