Java的BufferedImage类是Image类的一个子类,它的主要作用是将一副图片加载到内存中并对其进行操作。通过BufferedImage,我们可以方便地对图片进行大小变换、变灰、设置透明度等修改操作。在Java中,可以使用ImageIO类的read方法将一副图片加载到内存中,生成一个BufferedImage对象。例如,可以使用以下代码加载一副图片到内存中:
```
BufferedImage bufferedImage = ImageIO.read(new FileInputStream(filePath));
```
另外,也可以使用以下代码加载一副GIF图片到内存中的BufferedImage对象:
```
BufferedImage image = ImageIO.read(new File("1.gif"));
```
通过BufferedImage类,我们可以很方便地对加载到内存中的图片进行各种操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
