如何克隆BufferedImage [英] How do you clone a BufferedImage

问题描述

Hi我有一个对象，其中有很多的缓冲图像，我想创建一个新的对象复制所有的缓冲图像到新的对象，但这些新的图像可能会改变，我不想改变原始对象图像

这是可能的，任何人都可以建议好的方法来做呢？
我已经考虑过getSubImage，但是在某处读取对子图像的任何更改都会返回到父图像。

我只想要能够获得新的完全独立的副本或克隆的BufferedImage

解决方案

这样的东西？

  static BufferedImage deepCopy（BufferedImage bi）{
 ColorModel cm = bi.getColorModel 
 boolean isAlphaPremultiplied = cm.isAlphaPremultiplied（）; 
 WritableRaster raster = bi.copyData（null）; 
 return new BufferedImage（cm，raster，isAlphaPremultiplied，null）; 
} 
  

Hi I have an object which has many bufferedimages in it, I want to create a new object copying all the bufferedimages into the new object, but these new images may be altered and i dont want the original object images to be altered by altering the new objects images.

is that clear?

Is this possible to do and can anyone suggest a good way to do it please? I have thought of getSubImage but read somewhere that any changes to the subimage are relected back to the parent image.

I just want to be able to get a fresh entirely seperate copy or clone of a BufferedImage

解决方案

Something like this?

static BufferedImage deepCopy(BufferedImage bi) {
 ColorModel cm = bi.getColorModel();
 boolean isAlphaPremultiplied = cm.isAlphaPremultiplied();
 WritableRaster raster = bi.copyData(null);
 return new BufferedImage(cm, raster, isAlphaPremultiplied, null);
}
