Hi everyono, I am using CImg library, and have a problem. I constructed 48*32 grayscale imag with:

CImg<double> image(48,32,1,1,0);

After that if, for instance i want to put some pixel to values 126, i use:

for(int i=0;i<48;i++){
for(int j=0;j<3;j++){
image(i,j)=126;}}

and than try to display that by:

CImgDisplay display(image);

All i get is black and white image, and i want to get a grayscale image, Can somebody tell what am i doing wrong.
Thanks in advance
