The InvertRect function inverts a rectangle in a window by performing a logical NOT operation on the color values for each pixel in the rectangle’s interior.
BOOL InvertRect(
HDC hDC, |
// handle of device context |
CONST RECT *lprc |
// address of structure with rectangle |
); |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
On monochrome screens, InvertRect makes white pixels black and black pixels white. On color screens, the inversion depends on how colors are generated for the screen. Calling InvertRect twice for the same rectangle restores the display to its previous colors.
