Pop!_OS 20.10 当我尝试启动 Lutris 时，它卡在“Lutris 正在启动”屏幕上。那是启动时的错误。

如何将输入图像转换为 3D 图像格式

我正在尝试用 C 编写图像旋转代码。

 int width, height, channels;
 unsigned char *img = stbi_load("butterfly.jpg", &width, &height, &channels, 0);

我正在阅读所见的图像。我想将这些图像数据转换为 3D（行、列、通道）数组格式，以便能够做到这一点：

if (Xprime >= 1 && Yprime >= 1 && Xprime <= height && Yprime <= width)
            {
                pixel = img[Xprime][Yprime];
        }
        returnedOutImage[i][j] = pixel;
    }
