How to get CImg pixel value?

Hi all,

I am new to CImg. I would like to know how to obtain a pixel value on a specific coordinate.


Thank in advance to all

I have never heard of CImg before, however it took me 2 minutes of reading the documentation to discover which method to use.

If you want to use a library reading the libraries documentation (admittedly if it exists) is a good place to start.

Maybe you could share your knowledge. If you can be bothered to look up the documentation for CImg and then reply, why not point us to the answer.

You can set the pixel data like you would elements of an array
see T& operator()
