用Java怎么从一个图片中提取出部分的图像
我不想用PhotoShop, 或 inkscape, 原因是前者没有， 后者不会用。

如下图，

怎么把这10个图像用java分离成单独的图像， 或怎么设定访问固定的区域， 求解？

用Windows自带的画笔多好。。。

假设你原始图片是：Image source;

BufferedImage img = new BufferedImage(50, 50);
Graphics g = img.getGraphics();
g.drawImage(source, dx1, dy1, dx2, dy2, sx1, sy1, sx2, sy2, null);

img图片左上右下坐标位置：
dx1 - the x coordinate of the first corner of the destination rectangle.
dy1 - the y coordinate of the first corner of the destination rectangle.
dx2 - the x coordinate of the second corner of the destination rectangle.
dy2 - the y coordinate of the second corner of the destination rectangle.
source图片左上右下坐标位置：
sx1 - the x coordinate of the first corner of the source rectangle.
sy1 - the y coordinate of the first corner of the source rectangle.
sx2 - the x coordinate of the second corner of the source rectangle.
sy2 - the y coordinate of the second corner of the source rectangle.
