| 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 ImGearRecPreprocessingSettings.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. |
| GRAY | 4 | For a color image: a grayscale image is created internally. For a bitonal or grayscale image: no reduction is performed while loading 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 ImGearRecPreprocessingSettings.ReductionThreshold property. |
Remarks
These values specify how the different image types will be converted either
during the primary image conversions or during the secondary image conversions.
