An Exception is Thrown when reading a pixel at a negative position. #1
Description
Basically, I have two screens, one in the center, and one on my left. When I attempt to pick a pixel on my left screen, the program throws an exception indicating that it cannot take a negative input.
The coordinates provided for the mouse's position are incorrect and provide negative positions. This is a pretty minor problem in practice, because the 'BitmapSource' object indicates that my full desktop is captured.
With that said, a related issue that you (Or I) should fix is in 'ColorConverter.GetColor'. You are currently allocating one byte per-pixel on the active row of the screen, then using the first four elements. What you're looking for is the number of channels, not the height of the screen.
