The InvertRgn
function inverts the colors in the specified region.
BOOL InvertRgn(
|
HDC hdc, |
// handle of device
context |
|
HRGN hrgn |
// handle of region
to be inverted |
|
); |
|
Parameters
hdc
Identifies
the device context.
hrgn
Identifies
the region for which colors are inverted. The region s coordinates are presumed
to be logical coordinates.

function fails, the return value is zero.
Remarks
On monochrome
screens, the InvertRgn function makes white pixels black and black
pixels white. On color screens, this inversion is dependent on the type of
technology used to generate the colors for the screen.
