如何克隆 BufferedImage
我有一个包含许多缓冲图像的对象，我想创建一个新对象，将所有缓冲图像复制到新对象中，但是这些新图像可能会被更改，我不希望原始对象图像被更改通过更改新对象图像.
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 don't want the original object images to be altered by altering the new objects images.
清楚吗?
这是可能的吗?有人可以提出一个好的方法吗?我曾考虑过 getSubImage，但在某处读到，对子图像的任何更改都会被反射回父图像.
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.
我只是希望能够获得一个全新的、完全独立的 BufferedImage 副本或克隆
I just want to be able to get a fresh entirely separate copy or clone of a BufferedImage
推荐答案
像这样?
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);
}
