【转】图片读取

(利用imageio类的读写函数)

importjavax.imageio.ImageIO;
importjava.io.File;
importjava.io.IOException;
importjava.awt.image.BufferedImage;

publicclassChangeImageStyle...{

publicstaticvoidmain(Stringargs[])throwsIOException...{

FileinputFile=newFile("test.bmp");
BufferedImageinput=ImageIO.read(inputFile);

//转换为gif格式的图片
FileoutputFile=newFile("test.gif");
ImageIO.write(input,"GIF",outputFile);

//转换为jpg格式的图片
outputFile=newFile("test.jpg");
ImageIO.write(input,"JPG",outputFile);

//转换为png格式的图片
outputFile=newFile("test.png");
ImageIO.write(input,"PNG",outputFile);
}
}
