    ImGearOCRReductionMode Enumeration
    In This Topic
    Identifies image conversion modes to be applied for conversions from grayscale or 24-bit color image sources.
    Syntax
    'Declaration

    'Usage

    MemberValueDescription
    AUTO0This 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.
    GLOBAL3This 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.
    NO2There is no conversion while loading the image. The image is loaded without any conversion (i.e. a color image retains its color attributes).
    SET1This 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.
    Remarks
    These values specify how the different image types will be converted either during the primary image conversions or during the secondary image conversions.
