我正在开发一个程序，将图像转换为适用于Minecraft基岩和Java版本的.mcfunction文件。在我的程序中，我使用for循环插入image.getpixel中的x和y坐标。但是，整整一晚我都被错误困住了
TypeError：getpixel（）带有2个位置参数，但给出了3个
，不确定是什么原因造成的。我以前没有这个问题，但是最近我添加了一个功能，该功能可以旋转图像预览，并且突然之间就开始发生这种情况。这是我的程序：

答案 0 :(得分：0)
好的，因此错误即将到来，因为您已经写了
imgfcalc.getpixel(i,j)
并且根据错误，方法getpixel仅采用两个位置参数 但是给定i，j是两个位置参数，一个位置参数是imgfcalc（self）。因此，您总共给出了3个参数 并且您需要删除一个参数。 函数可能使用元组/列表中的i，j参数 尝试将参数设为（i，j）而不是i，j
