图标的像素原始图像格式

Question

我开始使用SDL 2库开发游戏并遇到问题：我在Visual Studio中指定了图标，但SDL_Window的图标没有改变。我在SDL wiki上找到了这段代码：

SDL_Surface *surface;     // Declare an SDL_Surface to be filled in with pixel data from an image file
        Uint16 pixels[16 * 16] = {  // ...or with raw pixel data:
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,
            0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff, 0x0fff,

            0x1767, 0x5aaa, 0xf013, 0xf001, 0xf000, 0x0fff, 0x7fff, 0xf124,
            0x0fff, 0x089a, 0x0578, 0x0fff, 0x089a, 0x0013, 0x0245, 0x0eff,

            0x5356, 0x2246, 0x0346, 0x0356, 0x0467, 0x0356, 0x0467, 0x0467,

        };
        surface = SDL_CreateRGBSurfaceFrom(pixels, 16, 16, 16, 16 * 2, 0x0f00, 0x00f0, 0x000f, 0xf000);

        // The icon is attached to the window pointer
        SDL_SetWindowIcon(wind, surface);

        // ...and the surface containing the icon pixel data is no longer required.
        SDL_FreeSurface(surface);

我的问题是“ Uint16像素到底包含什么，如何从图像（.ico，.bmp）获取此数据？”
