我正在尝试做的是我正在尝试拍摄图像并将其设为平铺图像。起始图像应如下所示。 http://i1146.photobucket.com/albums/o525/walroid/letter_Q_grayscale_zpsd3b567a7.jpg 然后图像变成瓷砖然后应该是这样的：http: //i1146.photobucket.com/albums/o525/walroid /replicate_example_zps5e5248e8.jpg 在我的代码中，图片被保存到一个数组中，该数组被调用到该方法中。我想要做的是复制该数组，然后将其放入另一个将复制图像的数组中。我怎么做？这是我的整个代码：
