读取24位BMP图像并生成JPG缩略图(一)

读取24位BMP图像并生成JPG缩略图(一)(5)      int height=image.getHeight(null);                                  //得到源图长
     BufferedImage tag=new BufferedImage(wideth/2,height/2,BufferedImage.TYPE_INT_RGB);
     tag.getGraphiCS().drawImage(image,0,0,wideth/2,height/2,null);     //绘制缩小后的图
     FileOutputStream out=new FileOutputStream("/newfile.jpg");         //输出到文件流
     JPEGImageEncoder encoder=JPEGCodec.createJPEGEncoder(out);     
     encoder.encode(tag);                                               //进行JPEG编码
     out.close();       //关闭输出流                     
 }catch (Exception e){
     System.out.println(e);
        }
        return result;
