Types

BinarizationFilterPreset

enum BinarizationFilterPreset : Enum<BinarizationFilterPreset>

Preset of parameters for custom binarization filter.

BrightnessFilter

data class BrightnessFilter(var brightness: Double = 0.0) : ParametricFilter, Parcelable

Brightness adjustment filter.

ColorDocumentFilter

ImageProcessor

interface ImageProcessor

Interface for ImageProcessor API. See class documentation for more details.

LegacyFilter

data class LegacyFilter(var filterType: Int = 0) : ParametricFilter, Parcelable

Deprecated. Returns the input image unchanged.

OutputMode

enum OutputMode : Enum<OutputMode>

Output mode of binarization filter.

PageBinarization

enum PageBinarization : Enum<PageBinarization>

Binarization behavior to apply when adding a page to a PDF/TIFF.

ParametricFilter

sealed class ParametricFilter : Parcelable

Base class for all parametric filters.

ScanbotBinarizationFilter

data class ScanbotBinarizationFilter(var outputMode: OutputMode = OutputMode.BINARY) : ParametricFilter, Parcelable

Automatic binarization filter. This filter is a good starting point for most use cases.

ScanbotSdkImageProcessor

class ScanbotSdkImageProcessor : SelfDisposable, ImageProcessor

API for image processing.

WhiteBlackPointFilter

data class WhiteBlackPointFilter(var blackPoint: Double = 0.0, var whitePoint: Double = 1.0) : ParametricFilter, Parcelable

Maps image value channel so that all the pixels darker than the black point are set to 0, all the pixels brighter than the white point are set to 255, and the pixels in between are linearly scaled.
