| Member | Value | Description |
|---|---|---|
| AUTO | 0 | 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 | 3 | 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 | 2 | 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 | 1 | 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. |
