A shallow copy of the image that also has a region that contains the removed inverted text.
If InvertedTextCommandFlags.SingleRegion| InvertedTextCommandFlags.LeadRegion has been set in the Flags property, then when InvertedTextCommand returns, this property is updated with a shallow copy of the image that also has a region that contains the removed inverted text. So set the InvertedTextCommandFlags.SingleRegion| InvertedTextCommandFlags.LeadRegion flags. Dispose of the region when it is no longer needed.
Run the InvertedTextCommand on an image.
