Parameter is not valid - Bitmap constructor error

Question

I am trying to initiate a new Image object here:

Bitmap image = new Bitmap(21241,21241);

The overloaded constructor that i intend to use is this one:

public Bitmap(
    int width,
    int height
)

I do understand that the value 21241 is a bit but still under the int range than why it says invalid parameter?

Already check this answers:
