Parameters

rect: Rectangular region of the image to invert.

Remarks

This method performs immediate inversion of the color of each pixel within the specified rectangular region of the image. For example, white becomes black, and black becomes white. This method ignores the image inversion mode setting (ImGearOCRPreprocessingSettings.InversionMode property). The inverted image replaces the original one and is available to the recognition engine and the application.
