Java批量将BMP转换为JPG
public static void main(String[] args) throws Exception{
//前提是文件夹内都是bmp文件,无论层级transfImg(new File("C:\\Users\\Desktop\\111"));
}
private static void transfImg(File file) throws Exception{
if(file.isDirectory()){
for (File listFile : file.listFiles()) {
transfImg(listFile);
}
}else {
Image img = ImageIO.read(file);
BufferedImage tag = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
tag.getGraphics().drawImage(img.getScaledInstance(img.getWidth(null), img.getHeight(null), Image.SCALE_SMOOTH), 0, 0, null);
String path = file.getAbsolutePath();
FileOutputStream out = new FileOutputStream(path.substring(0,path.length()-4)+".jpg");
// JPEGImageEncoder可适用于其他图片类型的转换
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(tag);
out.close();
//不保留源文件(可选)file.delete();
}
}
