我正在尝试使用 Java 将几个图像组合成一个更大的图像。传入的图像都是 127 x 宽 293 的高度。想法是将许多图像传递给该方法,该方法获取图像并将它们构建成另一个更大的图像。将有一个较大图像的布局,其中总共 12 个可能的图像可以输入到较大的图像中,均匀分布(2 行,每行 6 个图像,不重叠)。如果传入的图像少于 12 个,则仅填充第一个(但有很多空格),图像的其余部分将是白色的,因为背景将是白色的。当我运行程序时,它会打印更大的图像,但它只会填充显示左上角第一张图像的第一个空间,而不管传入多少张图像。背景也是粉红色,而不是预期的白色背景。我只是 Java 的初学者,所以我正在努力解决其中的一些学习难题。关于如何解决我的问题的任何建议?(代码复制如下以供参考)谢谢!
