java将图片分割为几个部分示例

以下代码使用java将图片分割为几个部分，大家参考使用吧

public class segmentationimage{

   public static icon segmentation(string imagename,int width,int height,int height,int width) throws exception{
  // 准备分割图片

     bufferedimage img1=imageio.read(new file(imagename));
     int half_w=img1.getwidth();
   int rgb[]=new int[half_w*img1.getheight()];
   img1.getrgb(0, 0, half_w, img1.getheight(), rgb, 0, half_w);
   bufferedimage img_half=new bufferedimage(half_w, img1.getheight(), bufferedimage.type_int_argb);
   img_half.setrgb(width,height,height,img1.getheight(), rgb,width,half_w);
   icon returnicon = new imageicon(img_half);
      return returnicon;
}
}
