GetPixel(ScreenWidth, ScreenHeight) throws exception

Question

I have a 1080P monitor. Doing

int j Screen.PrimaryScreen.Bounds.Width;
int k = Screen.PrimaryScreen.Bounds.Height;
_Bitmap.GetPixel(j, k).GetBrightness();

(_Bitmap size is equal to my screen bounds), it throws an exception saying "Parameter must be positive and < height".

Answer 1

Width and Height start counting at 1, the indexes used in GetPixel() start at 0. So when trying to acces the Pixel at (Width,Height) nothing is found

To correct the error change the code to (for example):

int width = Screen.PrimaryScreen.Bounds.Width;
int height = Screen.PrimaryScreen.Bounds.Height;

_Bitmap.GetPixel(width-1,height-1).GetBrightness();
