<h5 id="C1_Framework_Drawing_Gdi_DeviceContexts_DeviceContext_InvertRectangle_System_Drawing_Rectangle__remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>On monochrome screens, InvertRectangle makes white pixels black and black pixels white. On color screens,
the inversion depends on how colors are generated for the screen. Calling InvertRectangle twice
for the same rectangle restores the display to its previous colors.</p>
