Why PictureBox. It's not a picture or a bitmap. Anyway, why asking about it? Now, save where? What did you try?

I understand about picture, my concern is PictureBox; most likely, you don't need it.

Solution 1

You should be using bitmaps. You can copy a rectangle region of a bitmap in this way:

That's all you need. And you can save new bitmap the way you want.
