    Let me assume for a second that you are using dos mode 13h. If you want to get a pixel then do something like:
    Code:
    //screen_buffer will be the buffer where I could find pixels
    //SCREE_WIDTH will be the horizonal resolution of the screen.
    unsigned char pixelAt(int x, int y){
        return screen_buffer[y*SCREEN_WIDTH + x];   
    }
