Identifies image conversion modes to be applied for conversions from grayscale or 24-bit color image sources.

Member | Description |
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 ImGearRecPreprocessingSettings.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. |
GRAY | 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 | 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 ImGearRecPreprocessingSettings.ReductionThreshold property. |
