AddInvertRegion Method of the ImageModification Object
This method adds a new inversion region to the internal array of inversion regions of the ImageModification object. To remove all the inversion regions previously added call the IImageModification::ClearInvertRegions method. If the modification must be applied to a single color (or gray) plane of the image, coordinates of the region should be specified on this color (gray) plane. If the modification must be to the whole ImageModification, the coordinates should be specified on the deskewed black-and-white image plane.
