Gdi::InvertRect_I (Windows Embedded CE 6.0)
1/6/2010
This method inverts a rectangle in a window by performing a logical NOT operation on the color values for each pixel in the interior of the rectangle.
Syntax
static WINUSERAPI BOOL WINAPI InvertRect_I(
HDC hdc,
const RECT* lprc
);
Parameters
- hdc
[in] Handle to the device context.
- lprc
[in] Pointer to a RECT structure that contains the logical coordinates of the rectangle to be inverted.
Return Value
Nonzero indicates success.
Zero indicates failure.
To get extended error information, call GetLastError.
Remarks
On monochrome screens, Gdi::InvertRect_I makes white pixels black and black pixels white.
On color screens, the inversion depends on how colors are generated for the screen.
Calling Gdi::InvertRect_I twice for the same rectangle restores the display to its previous colors.
