示例1: main

//Declare Images buffer
Image input1, input2;
Image output;
//Reading a greyscale image
input2.Load("./img/background_image.pgm");
input1.Load("./img/input_image.pgm");
// allocate the output_image
output.Build(input1.width, input1.height, input1.bpp);
//copia dell'immagine, copiando i buffer
for (int j=1; j<input1.height; ++j){
for (int i=1; i<input1.width; ++i){
int index = i + j * input1.width;
