        {
            CalcThresh();
        }




    }
}

Heres the first image i used

It works fine like this for example :

But for other image it crash whenever i picked a mode :

This one of the pic that made my program crashed :

This how the form deisgn looks like :

Im studying this for test so if someone can help me find the problem i really

appreciate it.

Thx Before

Answer 1

Replace this:

Image<Gray, byte> temp = new Image<Gray, Byte>(edited.Height, edited.Width);

With this:

Image<Gray, byte> temp = new Image<Gray, byte>(edited.Width, edited.Height);
