hello guys.
I want to have a algo or c-program that can save image pixel values in a matrix similar like we do in MATLAB
I have a bmp image which black and white only that its pixel values is only 0 or 255 (black or white)
Now I want to save all that pixel values in a 2D matrix in a c-program
so, is there any way to this?

What I have tried:

I used Cimg and imagemagick they are very slow.
