| AUTO | This has an effect on grayscale or 24-bit color images: a B/W image is created in Engine's memory. An automatic adaptive thresholding algorithm is applied for the binarization of the image. Use ImGearOCRPreprocessingSettings.ReductionBrightness property to fine tune the threshold calculation. | 
| GLOBAL | This has an effect on grayscale or 24-bit color images: a bitonal image is created 
            internally. An automatic thresholding algorithm with a page-level global threshold value is 
            applied for the binarization of the image. | 
| NO | There is no conversion while loading the image. The image is loaded without any conversion 
            (i.e. a color image retains its color attributes). | 
| SET | This has an effect on grayscale or 24-bit color images: a bitonal image is created internally. Thresholding with a user defined threshold value, set by ImGearOCRPreprocessingSettings.ReductionThreshold property. |
