Graph an image of a two-dimensional array

I am passing an image to a one-dimensional array. This must be passed to another two-dimensional array from which I must graph the saved image. the image has its beginning in 1078 and ends in 3078 , the problem that I have is to graph the image since it is running graph. This is the function that I have.

void pasoArreglo(FILE* Archivo) {

char datos[3078];
fread(datos, 1, 3078, Archivo);
char dimenciones[80][25];
for (int y = 0; y < 25; y++) {
    for (int x = 0; x < 80; x++) {
        dimenciones[x][y] = datos[1078 + ((y * 2) + x)];
    }
}

char Rcolor = 0, Gcolor = 0, Bcolor = 0;

for (int y = 24; y >= 0; y--) {
    for (int x = 0; x < 80; x++) {

        if (dimenciones[x][y] & 0x1) { Rcolor = FOREGROUND_RED; }
        if (dimenciones[x][y] & 0x2) { Gcolor = FOREGROUND_GREEN; }
        if (dimenciones[x][y] & 0x4) { Bcolor = FOREGROUND_BLUE; }

        gotoxy(x, y);
        setColor(Rcolor | Gcolor | Bcolor);
        printf("%c", 219);



        Rcolor = 0;
        Gcolor = 0;
        Bcolor = 0;
    }       
  }
}
