如何将超链接插入BuffereImage（java）的指定区域？

我在绘图面板上显示了一个java BuffereImage。可以说，我如何“激活”该图像的特定区域，使其成为一个可点击区域，并附加一个特定的超链接？谢谢。

您有很多选择

使用“地图图像”定义图像的可单击位置。这将需要第二个图像的大小与第一个图像的大小相同，并带有可在运行时识别的绘制区域，以确定它们是否可单击

定义一系列表示可单击位置的“形状”。这些区域可以命名并保存到文件中，从而能够独立于代码定义这些区域

下面的示例使用这两种方法

“大师”形象

“地图”图像

将鼠标/运动监听器添加到

绘图窗格中

，当鼠标移过/单击相关区域时，执行一些任务…首先，感谢您花费大量精力编写这些内容。不幸的是，那个代码对我来说有点太多了。如果您能帮助理解，我们将不胜感激。你的代码不仅仅是建立一个可点击的区域吗？有没有办法把它归结为一些简单的东西，比如识别像素位置，画框，用特定的超链接使框可以点击？谢谢
