Tugas 5

Program di bawah ini merupakan program utama dari program untuk pengenalan angka dari 0 - 9 :

//Konversi dari data pixel ke RGB dan dari data RGB ke data Pixel:
void WarnaToRGB(long int warna,int *Red, int *Green, int *Blue)
{
*Red = warna & 0x000000FF;
*Green = (warna & 0x0000FF00) >> 8;
*Blue = (warna & 0x00FF0000) >> 16;
