Thread: photo in program

I'd imagine you'd want to use a graphics API like DirectX or OpenGL to handle that.

Displaying images is hard. Looking at your recent threads, you probably wouldn't be up to the task at the moment. I mean, you could try it if you wanted, but it would involve a lot of code. Here's a simple SDL program that displays an image.

Code:

#include "SDL.h"

int main(int argc, char *argv[]) {
    SDL_Surface *image;
    SDL_Event event;
    int quit = 0;

    if(SDL_Init(SDL_INIT_VIDEO) < 0) return 1;

    image = SDL_LoadBMP("file.bmp");
    if(!image) return 1;

    if(!SDL_SetVideoMode(image->w, image->h, 0, SDL_SWSURFACE)) return 1;

    while(!quit) {
        SDL_BlitSurface(image, 0, SDL_GetVideoSurface(), 0);

        while(SDL_WaitEvent(&event)) {
            switch(event->type) {
            case SDL_QUIT:
            case SDL_KEYDOWN:
                quit = 1;
            }
        }
    }

    SDL_FreeSurface(image);
    return 0;
}

I just typed that into the quick reply box, so there's no guarantee it will work. But you can see how complicated things can be with images . . . .
