看看 SDL_image 库.它提供了类似IMG_LoadPNG的功能，可以将图片作为" SDL_Surface加载. 由于您已经在使用SDL，因此它应该非常适合您的程序.

Have a look at the SDL_image library. It offers functions like IMG_LoadPNG that load your picture "as an" SDL_Surface. Since you already work with SDL this should fit quite well in your program.

摘录自 SDL_image文档:

// Load sample.png into image
SDL_Surface* image = IMG_Load("sample.png");
if (image == nullptr) {
    std::cout << "IMG_Load: " << IMG_GetError() << "\n";
}
