如何在Java中裁剪图像？ [英] How do I crop an image in Java?

问题描述

我想用鼠标手动裁剪图像。

假设图像有一些文字，我想从图像中选择一些文字，然后
为此我想要使用鼠标裁剪该区域。

I want to crop an image manually using the mouse.
Suppose the image has some text, and I want to select some text from an image, then for that purpose I want to crop that area by using the mouse.

推荐答案

我发现裁剪缓冲图像最有用的解决方案是使用getSubImage（x，y，w，h）;

The solution I found most useful for cropping a buffered image uses the getSubImage(x,y,w,h);

我的裁剪程序最终看起来像这样：

My cropping routine ended up looking like this:

  private BufferedImage cropImage(BufferedImage src, Rectangle rect) {
      BufferedImage dest = src.getSubimage(0, 0, rect.width, rect.height);
      return dest; 
   }
