Inverts a rectangle in a window by performing a logical NOT operation on the color values for each pixel
#include <WinAPIGdi.au3>
_WinAPI_InvertRect ( $hDC, $tRECT )
| $hDC | Handle to the device context. |
| $tRECT | $tagRECT structure that contains the logical coordinates of the rectangle to be inverted. |
| Success: | True |
| Failure: | False |
On monochrome screens, the _WinAPI_InvertRect() makes white pixels black and black pixels white. On color screens,
the inversion depends on how colors are generated for the screen. Calling _WinAPI_InvertRect() twice for the same
rectangle restores the display to its previous colors.
