In This Topic

)

Parameters

rectangle: A System.Drawing.Pointstructure that contains the logical coordinates of the rectangle to be inverted.

Exceptions

Exception	Description
C1.Framework.SystemErrorException	Defines an exception class to handle the system error.

Remarks

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.
